If a mark goes just after another mark then replace the old mark rather than add the new. * jit/jit-cache.c (_jit_cache_get_bytecode) (_jit_cache_get_native): fix offset for the last bytecode mark. 2007-11-13 Aleksey Demakov * tools/Makefile.am (noinst_HEADERS): add gen-apply-macosx.h 2007-11-08 Aleksey Demakov * include/jit/jit-plus.h, jitplus/jit-plus-function.cpp (new_label): add c++ wrapper for jit_function_reserve_label. * include/jit/jit-plus.h (clear_recompilable): fix a typo. 2007-10-07 Aleksey Demakov * jit/jit-rules-x86.ins (JIT_OP_JUMP_TABLE): fix jump table code generation. * include/jit/jit-function.h: * jit/jit-function.c (jit_function_reserve_label): add new function to create labels for jump tables. 2007-06-11 Aleksey Demakov * jit/jit-insn.c (accumulate_relative_offset): remove. * jit/jit-insn.c (find_base_insn, jit_insn_load_relative) (jit_insn_store_relative, jit_insn_add_relative): add find_base_insn function that should finally optimize relative instructions correctly. 2007-06-10 Aleksey Demakov * tools/gen-rules-parser.y (gensel_output_clauses): alter selection logic so that "reg" rules are chosen over "local" in case the value is used again in the same basic block. * jit/jit-rules-x86.ins: tweak COPY rules for bytes, shorts, and ints. * jit/jit-live.c (forward_propagation, backward_propagation) (is_copy_insn): do not perform copy propagation if JIT_OP_COPY_INT is used for byte and short values. 2007-05-28 Aleksey Demakov * jit/jit-live.c (forward_propagation, backward_propagation): do not optimize addressable and volatile values. 2007-05-28 Aleksey Demakov * jit/jit-live.c (_jit_function_compute_liveness) (forward_propagation, backward_propagation): add simple copy propagation that works only within basic blocks. * jit/jit-value.c (jit_value_ref): do not set the live flag here as this is done in jit-live.c now. 2007-05-26 Klaus Treichel * jit/jit-intrinsic.c: Fix conversion from ulong to nfloat for values greater that jit_max_long. 2007-05-26 Aleksey Demakov * jit/jit-insn.c (jit_insn_store): remove incorrect optimization that eliminates intermediate value without knowledge of its later use. 2007-04-04 Aleksey Demakov * jit/jit-reg-alloc.c (commit_output_value): fix compilation for archs without register stack (thanks Klaus). 2007-03-04 Aleksey Demakov * configure.in: update working version to "0.1.1". 2007-03-03 Aleksey Demakov * include/jit/Makefile.am: add jit-arch.h to BUILT_SOURCES. * doc/Makefile.am: add extract-docs.sh, mkhtml.sh, mkpdf.sh to EXTRA_DIST. * configure.in: bump version to 0.1.0. * NEWS: update news for the 0.1.0 release. 2007-02-25 Aleksey Demakov * jit/jit-reg-alloc.c (adjust_assignment, _jit_regs_gen): the ops that have dest value on x87 stack but have no x87 input values need the dest register to be adjusted after spilling too. (is_register_occupied, clobbers_register): undo is_register_occupied logic introduced 2007-02-12. 2007-02-14 Aleksey Demakov * jit/jit-function.c (compile_block): check if cache is full and exit if so. 2007-02-13 Aleksey Demakov * doc/texinfo.tex: remove an ancient file version from the tree. automake --add-missing as well as auto_gen.sh add an up-to-date version of it. * jit/jit-insn.c, jit/jit-rules-interp.c: * jitplus/jit-plus-value.cpp, jitplus/jit-plus-function.cpp: fix texinfo comments. 2007-02-12 Aleksey Demakov * jit/jit-dump.c (jit_dump_function): flush the output stream upon dumping the function. * jit/jit-function.c (cleanup_on_restart, reset_value): add new functions to clean up the compilation state on restart. (compile): replace the code that did cleanup on restart with a call to cleanup_on_restart() which does this job more thoroughly. * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: remove _jit_regs_abort() function as the new cleanup-on-restart code makes it superflows. * jit/jit-reg-alloc.c (is_register_occupied): add new function; (clobbers_register, spill_clobbered_register, _jit_regs_gen): fix a problem that shows up with the new cleanup method. * tools/gen-rules-parser.y (gensel_output_clauses): the conditions for the local and frame patterns are changed. If the value is used before it is defined then both in_frame and in_register flags are clear. This situation is perfectly valid if there is a backward branch form a point after the definition to a point before the use. So if the value is not a constant and it is not in a register assume that it is on the stack even if the in_frame flag is not set. 2007-02-10 Klaus Treichel * jit/jit-function.c: Use the on-demand compilation driver in jit_function_apply too. Return the functions' entry point if the function is allready compiled in jit_function_compile_entry. 2007-02-04 Aleksey Demakov * include/jit/jit-common.h, include/jit/jit-context.h, * include/jit/jit-function.h, jit/jit-internal.h, jit/jit-context.c, * jit/jit-function.c: provide for user defined on-demand compilation driver and delayed function entry point setup. 2007-01-28 Aleksey Demakov * jit/jit-reg-alloc.c (_jit_regs_gen, set_regdesc_flags): fix bugs introduced 2006-12-30 with loading registers for ternary ops and handling input register thrash. 2007-01-26 Aleksey Demakov * include/jit/jit-arch-x86.h (_JIT_ARCH_GET_CURRENT_FRAME): tweak gcc version of the macro. * jit/jit-apply-x86.c (_jit_create_redirector): redirector does not use stack frame so remove frame set up and restore instructions. 2007-01-23 Aleksey Demakov * jit/jit-internal.h, jit/jit-function.c: remove the closure_entry field from jit_function_t. Find this value on the fly in jit_function_to_closure() and jit_function_to_vtable_pointer() to be equal either to entry_point or indirector fields. * jit/jit-rules-alpha.ins, jit/jit-rules-x86.ins: use jit_function_to_closure() instead of the closure_entry field. 2007-01-17 Aleksey Demakov * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: complete special x87 arithmetic support, for other x87 instructions reverse the order of arguments on the stack. * jit/jit-rules-x86.ins: take advantage of regalloc's x87 arithmetic support. Also do not clobber the entire x87 stack for atan, sin, and cos rules. 2007-01-12 Heiko Weiss * jit/jit-function.c: Fix a typo in jit_function_from_vtable_pointer which breaks the build if libjit is built in interpreter mode. 2007-01-04 Thomas Cort * jit/jit-rules-alpha.c: register class should not include FIXED registers. * .cvsignore, tools/.cvsignore, tutorial/.cvsignore: updated the .cvsignore files to ignore some generated files. 2007-01-03 Thomas Cort * jit/jit-rules-alpha.c: initialize alpha register classes. Fix signed-ness warnings. 2007-01-02 Aleksey Demakov * jit/jit-rules-x86.ins: add JIT_OP_IMIN_UN rule (based on the patch #5540 by Kirill Kononenko). * jit/jit-reg-alloc.c (set_regdesc_value, set_regdesc_register) (choose_output_register): handle EARLY_CLOBBER flag for dest value. 2006-12-30 Aleksey Demakov * jit/jit-reg-class.c, jit/jit-reg-class.h, jit/Makefile.am: add register classes. * jit/jit-rules-x86.c (_jit_init_backend): initialize x86 register classes. * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: specify register class for each value and scratch register. Clean up interface. * tools/gen-rules-scanner.l, tools/gen-rules-parser.y: add register class declaration; "reg", "lreg", "freg" are not keywords anymore. "scratch" requires register class specification. "clobber" accepts register class which means all registers in the class are clobbered. Remove "only", "spill_before", "unary", and "binary" keywords. Replace "unary_note" and "binary_note" with "note". Also replace "unary_branch" and "binary_branch" with "branch". * jit/jit-rules-alpha.ins, jit/jit-rules-x86.ins: update according to the new rule syntax. 2006-12-20 Aleksey Demakov * jit/jit-thread.h, jit/jit-thread.c: add _jit_global_lock mutex. * jit/jit-init.c (jit_init): make sure that initialization is done only once. 2006-12-17 Klaus Treichel * include/jit/jit-function.h, jit/jit-function.c: Add the function jit_function_from_vtable_pointer to convert a vtable pointer back to the jit_function_t. 2006-11-29 Aleksey Demakov * jit/jit-reg-alloc.c (save_value): fix bug freeing stack register that is not on the stack top. 2006-11-27 Kirill Kononenko * jit/jit-rules-x86.c (throw_builtin): * jit/jit-rules-x86.ins (JIT_OP_THROW, JIT_OP_LOAD_PC): directly use the inst variable to get current PC value for the position-dependent code case (patch #5503). 2006-11-27 Aleksey Demakov * include/jit/jit-context.h: add JIT_OPTION_POSITION_INDEPENDENT option. * jit/jit-internal.h (struct _jit_builder): add position_independent field. * jit/jit-function.c (_jit_function_ensure_builder): initialize position_independent field. * jit/jit-rules-x86.c (throw_builtin): * jit/jit-rules-x86.ins (JIT_OP_ADDRESS_OF_LABEL, JIT_OP_JUMP_TABLE) (JIT_OP_THROW, JIT_OP_LOAD_PC): add position_independent check and stub missing cases. 2006-11-26 Kirill Kononenko * jit/jit-rules-x86.ins: if JIT_USE_SIGNALS is defined do not emit explicit division by zero check (patch #5278). 2006-11-26 Aleksey Demakov * jit/jit-reg-alloc.c (choose_output_register): fix global register use cost computation. * jit/jit-rules-x86.ins: mark as commutative JIT_OP_IADD, JIT_OP_IMUL, JIT_OP_LADD, JIT_OP_IAND, JIT_OP_IOR, JIT_OP_IXOR, JIT_OP_LAND, JIT_OP_LOR, JIT_OP_XOR rules. 2006-11-25 Aleksey Demakov * jit/jit-reg-alloc.c (exch_stack_top, free_value): fix freeing stack registers. 2006-11-25 Kirill Kononenko * jit/jit-rules-x86.ins: add JIT_OP_ISIGN and JIT_OP_LSIGN rules (patch #5533), optimize JIT_OP_LNEG rule (patch #5555). [with some modifications by Aleksey Demakov.] 2006-11-11 Aleksey Demakov * jit/jit-rules-x86.ins: add JIT_OP_IABS and JIT_OP_LABS rules. 2006-11-04 Aleksey Demakov * jit/jit-rules-x86.ins: make comparison opcodes use three-address patterns. 2006-11-01 Aleksey Demakov * jit/jit-reg-alloc.c (commit_input_value, commit_output_value): do not increment/decrement the top of the register stack in case of fp-value coalescing. 2006-10-23 Aleksey Demakov * jit/jit-rules-x86.ins: JIT_OP_EXPAND_INT and JIT_OP_EXPAND_UINT rules were broken for local byte or short values. Fixed by removing the local pattern altogether as the reg pattern produces the same code but without the bug. 2006-10-18 Aleksey Demakov * jit/jit-reg-alloc.c (clobbers_register, bind_value): enable coalescing of the destination value of a copy operation with the source value in a single register. * jit/jit-rules-x86.ins: tag COPY rules with the "copy" keyword and change patterns of TRUNC rules to have a separate destination register. 2006-10-16 Aleksey Demakov * jit/jit-interp.h, jit/jit-interp.c (_jit_run_function): * jit/jit-opcode.c, jit/jit-rules-interp.c (_jit_gen_insn): Repair struct handling broken since the last interpreter reorganization, remove unused interpreter opcodes. * jit/jit-rules-interp.c (_jit_gen_start_block): check if the fixup position is before the cache end. This prevents segmentation fault when the end of cache block is reached and jit_function_compile() attempts to generate more code (it checks for the cache end way too late). 2006-10-14 Aleksey Demakov * jit/jit-rules-interp.c (_jit_create_call_return_insns): fix return code in case of no return value or struct returned via pointer (this is just like 2006-02-20 fix for x86). * jit/jit-cfg.c (create_value_entry): an uninitialized value was used (thanks Klaus for spotting). 2006-10-02 Klaus Treichel * jit/jit-intrinsic.c: Fix a copy bug in jit_ulong_mul (replace - by *). 2006-09-25 Aleksey Demakov * include/jit/jit-arch-x86.h, include/jit/jit-arch-generic.h: add headers for architecture-specific definitions. (_JIT_ARCH_GET_CURRENT_FRAME): add macro to find the stack frame pointer. * include/jit/Makefile.am: create jit-arch.h as a symlink to one of the jit-arch-*.h files depending on the JIT_ARCH value. * configure.in: set JIT_ARCH according to the system architecture. * include/jit/jit-walk.h (jit_get_current_frame): * jit/jit-walk.c (jit_get_starting_frame): * tools/gen-apply.c (find_return_offset, detect_frame_offsets): use _JIT_ARCH_GET_CURRENT_FRAME macro if available. This resolves the problem with gcc 4.1.* where __builtin_frame_address() function is broken (thanks Klaus for identifing the problem). 2006-09-15 Radek Polak * include/jit/jit-insn.h, jit/jit-insn.c, jit/jit-debugger.c: new instruction jit_insn_mark_breakpoint_variable. 2006-09-14 Aleksey Demakov * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: remove "old" register allocation code. * configure.in: remove --enable-new-reg-alloc option. * jit/jit-rules-x86.ins: simplify JIT_OP_RETURN_LONG rule, lift code from load_small_struct() function to JIT_OP_RETURN_SMALL_STRUCT rule. * jit/jit-rules-x86.c: remove load_small_struct() function. 2006-09-09 Aleksey Demakov * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: * tools/gen-rules-parser.y: add _JIT_REGS_CLOBBER_STACK flag and use it in the code generated for "only" rules instead of the explicit stack top check followed by the _jit_regs_spill_all() call. 2006-09-02 Aleksey Demakov * jit/jit-interp.c (_jit_run_function): * jit/jit-rules-interp.c (_jit_gen_insn): remove last traces of register allocation from the interpreter. 2006-08-31 Klaus Treichel * configure.in: Replace the deprecated AM_PROG_LIBTOOL with the current AC_PROG_LIBTOOL. * jitdynamic/Makefile.am, jitplus/Makefile.am: Add -no-undefined to the LDFLAGS to enable building cygwin/mingw dlls. 2006-08-31 Aleksey Demakov * tools/gen-rules-scanner.l, tools/gen-rules-parser.y: add "frame" keyword that is just like "local" but forces the value out from the register into the stack frame. * jit/jit-rules-x86.ins: rewrite JIT_OP_COPY_STORE_BYTE, JIT_OP_ADDRESS_OF, and JIT_OP_COPY_STORE_SHORT rules using the "frame" keyword. * jit/Makefile.am, jit/jit-rules-x86.c: remove all references to jit-rules-x86.sel and jit-rules-x86.slc. * jit/jit-rules-x86.c: remove mov_memindex_reg_byte() and widen_byte() functions. 2006-08-30 Aleksey Demakov * jit/jit-interp.h, jit/jit-interp.c, jit/jit-opcode.c, jit/jit-rules-interp.h, jit/jit-rules-interp.c: major change in the internal interpreter instruction set. Now the stack is used only for function arguments. There are three pseudo-registers used instead of the stack for operands. One is used for the destination value, two others are used for the source values. The destination register is spilled after each instruction. This scheme obviates the need for register allocation for the interpreter backend. * jit/jit-function.c (jit_function_compile, compile_block): do not make register allocator calls if JIT_BACKEND_INTERP is defined. 2006-08-29 Aleksey Demakov * jit/jit-function.c (jit_function_from_pc): fix problem with wrong exception handler address for interpreter. * jit/jit-insn.c (jit_insn_return, jit_insn_return_ptr): do not pop the setjmp context for the interpreter backend because it takes care of this by itself. * jit/jit-rules.h, jit/jit-rules-alpha.c, jit/jit-rules-arm.c, * jit/jit-rules-interp.c, jit/jit-rules-x86.c, jit/jit-reg-alloc.c: move part of the _jit_gen_exch_top() functionality into a separate _jit_gen_move_top() function. * include/jit/jit-opcode.h: * jit/jit-opcode.c: add JIT_OPCODE_IS_JUMP_TABLE flag to mark the JIT_OP_JUMP_TABLE opcode. * jit/jit-dump.c (jit_dump_insn, dump_interp_code): add jump table dumping. 2006-08-28 Klaus Treichel * dpas/Makefile.am, jit/Makefile.am, tests/Makefile.am: Add missing sources to fix creation of tarballs (make dist). 2006-08-25 Yan Burman * jitdynamic/jit-cpp-mangle.c (mangle_type_gcc3): fix typo in is_unsigned usage (patch #5324) 2006-08-23 Thomas Cort * jit/jit-apply-alpha.c jit/jit-apply-alpha.h: Fix jit_redirector_size. alpha_call is 6 instructions, not 1. 5 to load the addr, 1 to call. * jit/jit-gen-alpha.h: add macros for fp sign copy and arithmetic. * jit/jit-rules-alpha.c: remove TODO() from unused functions. 2006-08-23 Aleksey Demakov * jit/jit-internal.h (struct _jit_function): change the type of redirector and indirector fields from char array to pointer. * jit/jit-function.c (jit_function_create): allocate the redirector and indirector buffers in the code cache. Call jit_flush_exec on these buffers. This fixes problems on alpha and some x86 linux distros. [This one is based on the initial solution suggested by Kirill Kononenko ]. * jit/jit-rules-x86.c (_jit_gen_redirector): ifdef out as this function is not used with the x86 backend. * jit/jit-reg-alloc.c: improve handling of three-address op codes. Now the dest register may re-use one of the input registers while previously it was always assigned to a separate register. Also restructure the code that will be used for better selection of x87 instructions (this code was not used before and still is not but this is about to change). * jit/jit-rules-x86.ins: rewrite all LOAD_RELATIVE and LOAD_ELEMENT ops for x86 as three-address. Adjust IREM ops so that they work correctly together with the latest allocator changes. 2006-08-22 Klaus Treichel * jit/jit-alloc.c: Use mmap and munmap to allocate executable memory where available because memory allocated with malloc is not executable on some archs/distros. 2006-08-21 Thomas Cort * jit/jit-rules-alpha.c jit/jit-gen-alpha.h: Add macros for int to fp and fp to int conversions. Use _jit_pad_bufer. 2006-08-20 Thomas Cort * jit/jit-apply-alpha.c jit/jit-apply-alpha.h jit/jit-rules-alpha.h jit/jit-rules-alpha.ins jit/jit-rules-alpha.c jit/jit-gen-alpha.h: Remove unnecessary code from the prolog, epilog, redirector, and closure. Implement > and >= opcodes for signed and unsigned values. 2006-08-19 Aleksey Demakov * jit/jit-reg-alloc.c (set_regdesc_flags): fix a problem with the clobber flag being ignored. The problem was introduced by the patch from 2006-06-17. 2006-08-15 Thomas Cort * jit/jit-rules-alpha.c jit/jit-rules-alpha.h jit/jit-rules-alpha.ins Add a TODO() macro to print unimplemented warnings. Fix some casting warnings. Implement _jit_gen_redirector(...). Fix JIT_CDECL_WORD_REG_PARAMS to use the correct parameter registers. Add some stack push and pop instructions. 2006-08-15 Kirill Kononenko * configure.in: add --enable-signals option; * jit/Makefile.am: add jit/jit-signal.c; * jit/jit-signal.c, jit/jit-internal.h: add _jit_signal_init(); * jit/jit-init.c: call _jit_signal_init() if JIT_USE_SIGNALS is defined. (patch #5278.) 2006-08-11 Thomas Cort * jit/jit-rules-alpha.c jit/jit-rules-alpha.ins Properly handle fixups on alpha. Implement JIT_OP_CALL_EXTERNAL for alpha. 2006-07-29 Aleksey Demakov * jit/jit-reg-alloc.c (use_cheapest_register): allow a register that contains an input value to be used as a scratch register. The input value in this case is copied to another register. This resolves the problem with JIT_OP_IREM rule that failed to allocate a scratch reg in a very specific case (all EBX, ESI, EDI regs are used as global, dividend is initially in ECX and copied to EAX:EDX pair where x86 idiv expects it to be). * jit/jit-reg-alloc.c (set_regdesc_flags): fix a bug. 2006-07-23 Thomas Cort * jit/jit-apply-alpha.c jit/jit-apply-alpha.h jit/jit-apply-func.h jit/jit-gen-alpha.h jit/jit-rules-alpha.c jit/jit-rules-alpha.h jit/jit-rules-alpha.ins Implement the redirector for alpha. Continue to implement more functions in jit/jit-rules-alpha.c. 2006-07-15 Thomas Cort * jit/jit-apply-alpha.c jit/jit-gen-alpha.h jit/jit-rules-alpha.h jit/jit-rules-alpha.c: Implement closure for alpha. Use jsr instead of bsr in alpha_call. Clean up prolog and epilog generation for alpha to be more readable. 2006-07-13 Thomas Cort * jit/jit-gen-alpha.h jit/jit-rules-alpha.c jit/jit-rules-alpha.h: Added trap barrier macro alpha_trapb. Implemented _jit_gen_prolog and _jit_gen_epilog for alpha. 2006-07-12 Aleksey Demakov * jit/jit-insn.c (jit_insn_move_blocks_to_start): fix problem with wrong order of blocks that were moved from the position just after the init_block and with disappearance of blocks after the empty init_block. 2006-07-12 Thomas Cort * README.alpha jit/Makefile.am jit/jit-apply-alpha.c jit/jit-apply-alpha.h jit/jit-elf-defs.h jit/jit-gen-alpha.h jit/jit-rules-alpha.c jit/jit-rules-alpha.h jit/jit-rules-alpha.ins /jit/jit-rules.h: Initial import of the code for the alpha port. 2006-07-06 Aleksey Demakov * jit/jit-rules-x86.ins: fix division by power of two. 2006-07-05 Aleksey Demakov * configure.in: make new register allocator the default. * jit/jit-reg-alloc.c (is_register_alive, compute_spill_cost): fix problem with destroying the end register of a long pair. 2006-07-03 Aleksey Demakov * jit/jit-rules-x86.ins: add JIT_OP_LOW_WORD, JIT_OP_EXPAND_INT, JIT_OP_EXPAND_UINT, JIT_OP_INT_TO_NFLOAT, JIT_OP_UINT_TO_NFLOAT, JIT_OP_LONG_TO_NFLOAT, JIT_OP_ULONG_TO_NFLOAT and rewrite JIT_OP_TRUNC_SBYTE, JIT_OP_TRUNC_UBYTE, JIT_OP_LOAD_PC rules. * jit/jit-rules-x86.c (_jit_opcode_is_supported): include .inc file instead of .slc if USE_NEW_REG_ALLOC is defined. 2006-06-28 Aleksey Demakov * tools/gen-rules-parser.y (gensel_output_code): * jit/jit-rules-x86.ins: use $1 for dest register instead of $0 for consistency. 2006-06-27 Aleksey Demakov * jit/jit-insn.c (accumulate_relative_offset): add function that accumulates JIT_OP_ADD_RELATIVE offsets. (jit_insn_store_relative, jit_insn_load_relative) (jit_insn_add_relative): use accumulate_relative_offset() instead of previous_relative() to find the offset from the original address and do not replace the accumulated instructions with JIT_OP_NOP as it was before. The old approach is problematic because it is unknown at this point if the values we accumulated are dead or they will be used by instructions added later. The dead code elimination pass removes unused values just as well but with enough knowledge to be safe. The new code also does not move JIT_OP_ADDRESS_OF towards the relative instructions that uses the address. Supposedly such move may be used by the code generator as a hint. However currently the code generator does not use such a hint. The old code is kept for reference #ifdefed out. 2006-06-17 Aleksey Demakov * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: implement support of the JIT_REGS_FREE_DEST flag for 3-argument instructions. Tweak reg alloc API. * tools/gen-rules-parser.y: adjust for reg alloc API changes. Use '$0' pattern element to refer to destination register in 3-argument instructions. * jit/jit-rules-x86.ins: rewrite JIT_OP_IDIV, JIT_OP_IDIV_UN, JIT_OP_IREM, JIT_OP_IREM_UN, JIT_OP_ADDRESS_OF_LABEL, JIT_OP_LOAD_RELATIVE_FLOAT32, JIT_OP_LOAD_RELATIVE_FLOAT32, JIT_OP_LOAD_RELATIVE_NFLOAT, JIT_OP_LOAD_ELEMENT_FLOAT32, JIT_OP_LOAD_ELEMENT_FLOAT64, JIT_OP_LOAD_ELEMENT_NFLOAT rules. 2006-06-16 Aleksey Demakov * jit/jit-rules-x86.sel, jit/jit-rules-x86.ins: fix JIT_OP_IDIV and JIT_OP_IREM rules for the divisor value of -1. 2006-06-09 Aleksey Demakov * jit/jit-rules-x86.ins: rewrite JIT_OP_STORE_RELATIVE_BYTE, JIT_OP_STORE_RELATIVE_SHORT, JIT_OP_STORE_RELATIVE_LONG, JIT_OP_STORE_RELATIVE_FLOAT32, JIT_OP_STORE_RELATIVE_FLOAT64, JIT_OP_STORE_RELATIVE_NFLOAT, JIT_OP_STORE_ELEMENT_LONG, JIT_OP_STORE_ELEMENT_NFLOAT rules to use regular pattern syntax instead of manual. 2006-06-03 Aleksey Demakov * jit/jit-rules-x86.ins: remove _jit_regs_free_reg() call from JIT_OP_RETURN_FLOAT32, JIT_OP_PUSH_FLOAT32, JIT_OP_RETURN_FLOAT64, JIT_OP_RETURN_NFLOAT, JIT_OP_PUSH_FLOAT64, and JIT_OP_PUSH_NFLOAT rules. With new ``gen-rules'' tool it frees wrong register and the right register is anyway freed automatically by the new allocator. * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c (_jit_regs_abort): add function to unbind values from registers if the code generation failed. This is required because new allocator may temporary bind constants to registers and if neither _jit_regs_commit() nor _jit_regs_abort() is called the constant value will be left in inconsistent state. The problem shows up when the end of a cache block has been reached and the compilation is restarted with a new block. * jit/jit-reg-alloc.c (_jit_regs_begin, _jit_regs_end): add convenience functions. * tools/gen-rules-parser.y (gensel_output_clauses): make generated code more readable by using _jit_regs_begin() and _jit_regs_end() where appropriate. * jit/jit-reg-alloc.c: allow to load the second part of a register pair to a global register. This is because x86 long arithmetics use 4 registers at once: EAX:EDX and ECX:EBX. At the same time EBX is the global register candidate. If the instruction clobbers the global register, the new allocator automatically pushes it on the stack before and pops after the instruction. * jit/jit-function.c (compile_block): modify trace messages. 2006-05-28 Klaus Treichel * jit/jit-insn.c: Add a code_label in initialize_setjmp_block just before the end_label that is moved with the block to the start of the function as jump target to the code. Otherwise other blocks moved to the start after this block will never be executed. 2006-05-27 Aleksey Demakov * jit/jit-reg-alloc.c (free_value, save_value): the value that has a global register and is also associated with a local register needs to be unbound from the local one. * jit/jit-reg-alloc.c (compute_spill_cost): assume that the spill cost for clean values is not zero. This keeps them in registers as long as there are free registers and thus reduces the number of loads. 2006-05-25 Aleksey Demakov * jit/jit-reg-alloc.c (use_cheapest_register): fix cost calculation again for 'spill_before' rules. The last patch did not work for values stored in global registers. Now both global and non-global values should be copied to EAX. 2006-05-25 Aleksey Demakov * jit/jit-reg-alloc.c (use_cheapest_register): fix cost calculation that sometimes caused overlooking free registers. This was a serious problem as there are some 'spill_before' rules that assume that the allocator will always choose EAX as the first free register. 2006-05-21 Aleksey Demakov * jit/jit-reg-alloc.h: add _JIT_REGS_FREE_DEST flag to be used in cases when the destination register is independent of any input register. * tools/gen-rules-parser.y: allow specification of independent destination register with '=reg' pattern syntax. (But the allocator does not yet handle this.) 2006-05-20 Aleksey Demakov * jit/jit-rules-x86.c (_jit_gen_exch_top): fix computation of stack register index. * jit/jit-reg-alloc.c (_jit_regs_assign): micro optimization by changing nesting order of for and if statements. 2006-05-19 Aleksey Demakov * jit-reg-alloc.h, jit/jit-reg-alloc.c: determine if input values need to be saved and evicted from registers to stack frame at the _jit_regs_assign() time. Uniformly save input values that need to in _jit_regs_gen(), do not save them in _jit_regs_commit(). This simplifies handling of stack registers. Remove initial_stack_top, exchanges, num_exchages fields from the _jit_regs_t struct. Add save and kill bit fields to the _jit_regdesc_t struct. Refactor and clean up code. 2006-05-10 Aleksey Demakov * jit/jit-reg-alloc.c (use_cheapest_register): check if the other part of a register pair clobbers global registers. * jit/jit-reg-alloc.c (exch_stack_top): run value exchange loop for all values in both registers. * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: delete on_stack field from the _jit_regdesc_t struct. * jit/jit-reg-alloc.c (_jit_regs_gen): handle instructions that have both stack and flat registers. * jit/jit-reg-alloc.c (spill_value): spilling an input value remember if we do register exchanges for other values. * jit/jit-reg-alloc.c: set touched registers more accurately. 2006-05-08 Aleksey Demakov * jit/jit-reg-alloc.c (commit_input_value, commit_output_value): fix extra spills introduced at 2006-05-05. * jit/jit-rules-x86.c (_jit_gen_spill_top): add missing jit_cache_end_output(). 2006-05-05 Aleksey Demakov * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: fix spilling and many problems with stack registers. 2006-05-04 Radek Polak * jit/jit-dump.c (dump_object_code): Now can dump to any stream not just stdout and stderr. 2006-05-01 Aleksey Demakov * jit/jit-rules-x86.sel, jit/jit-rules-x86.ins: fix problem with spilling dest register in JIT_OP_ADDRESS_OF rule. * jit/jit-rules-x86.ins: rewrite JIT_OP_STORE_RELATIVE_INT rule. 2006-04-23 Aleksey Demakov * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: register allocator now supports register sets that constrain the register assignment. * tools/gen-rules-parser.y: extend grammar to support register sets. Fix bugs. * jit/jit-rules-x86.ins: take advantage of new register allocator for JIT_OP_MEMORY, JIT_OP_MEMOVE, JIT_OP_MEMESET rules. 2006-04-20 Aleksey Demakov * tools/gen-rules-parser.y: fix generation of `if' pattern code. 2006-04-19 Aleksey Demakov * jit/jit-rules-x86.c (_jit_gen_load_value): fix compiler warning. * tools/gen-rules-parser.y (gensel_output_clauses): fix generation of clobber and scratch code. * tools/gen-rules-scanner.l, tools/gen-rules-parser.y: add `any' keyword. 2006-04-18 Aleksey Demakov * jit/jit-rules-x86.ins: add instruction selection rules for new register allocator. * jit/Makefile.am: build new instruction selection rules. * configure.in: add --enable-new-reg-alloc option. 2006-04-14 Aleksey Demakov * jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: new register allocator improved and extended to support stack registers. * jit/jit-internal.h (struct _jit_builder): * jit/jit-function.c (compile_block, jit_function_compile): add some tracing. * jit/jit-rules.h: * jit/jit-rules-arm.c: * jit/jit-rules-interp.c: * jit/jit-rules-x86.c: add _jit_gen_exch_top and _jit_gen_spill_top functions used by new allocator to handle stack registers. Add reg argument to _jit_gen_spill_global and_jit_gen_load_global functions. 2006-04-11 Aleksey Demakov * jit/jit-insn.c (jit_insn_start_catcher): initialize thrown_exception (the problem was found by Klaus). 2006-04-08 Aleksey Demakov * jit/jit-opcode.c: add jump table into jit_opcodes array. * tools/gen-rules-parser.y: extend pattern syntax to allow mark registers as clobbered. Fix bugs. 2006-04-07 Klaus Treichel * jit/jit-internal.h (struct _jit_function): add indirector field. * jit/jit-function.c (jit_function_compile, jit_function_create): use indirector. * jit/jit-apply-x86.h: define jit_indirector_size. * jit/jit-apply-func.h, jit/jit-apply-x86.c (_jit_create_indirector): add function that emits indirector code. 2006-04-07 Aleksey Demakov * jit/jit-insn.c (create_call_setup_insns): zero struct_return in case of tail calls (the problem was found by Klaus). 2006-04-03 Aleksey Demakov * tools/gen-rules-scanner.l: * tools/gen-rules-parser.y: add `reversible', `x87arith', and `copy' keywords. Fix bugs. 2006-03-23 Klaus Treichel * jit/jitc-except.c: Walk the stack to build the stack trace in jit_exception_get_stack_trace when the frame is not broken. 2006-03-23 Aleksey Demakov * tools/Makefile.am: * tools/gen-rules-parser.y, tools/gen-rules-scanner.l: add "gen-rules" tool that is similar to "gen-sel" but uses new register allocator. 2006-03-12 Klaus Treichel * jit/jit-insn.c: Pop the setjump context on return from functions with a catcher. 2006-03-11 Kirill Kononenko * jit/jit-insn.c (create_call_setup_insn): fix tail calls, work if the called function is not the callee function (thanks klausT for finding the bug). 2006-02-27 Aleksey Demakov * jit/jit-insn.c (jit_insn_convert): fix int->uint and uint->int conversion. 2006-02-26 Aleksey Demakov * jit/jit-rules-x86.sel: fix JIT_OP_STORE_RELATIVE_LONG. * jit/jit-gen-x86.h (x86_pop_mem, x86_pop_membase): fix opcode -- it was 0x87 (xchg) instead of 0x8f (pop). 2006-02-24 Aleksey Demakov * jit/jit-insn.c (jit_insn_address_of_label): fix a typo. * jit/jit-rules-x86.sel: fix JIT_OP_ADDRESS_OF_LABEL rule. 2006-02-20 Aleksey Demakov * jit/jit-rules-x86.c (_jit_create_call_return_insns): fix return code in case of no return value or struct returned via pointer. 2006-02-19 Aleksey Demakov * jit/jit-reg-alloc.h: * jit/jit-reg-alloc.c: Initial version of new local register allocator. * jit/jit-rules.h: * jit/jit-rules-arm.c (_jit_gen_spill_global): * jit/jit-rules-interp.c (_jit_gen_spill_global): * jit/jit-rules-x86.c (_jit_gen_spill_global): add function for spilling global registers. Used by the new allocator. Only x86 version is really implemented. 2006-02-13 Aleksey Demakov * jit/jit-internal.h (struct _jit_value): add index field. * jit/jit-value.c (alloc_value): initialize index field; * jit/Makefile.am (libjit_la_SOURCES): add jit-bitset.c and jit-cfg.c. 2006-02-12 Aleksey Demakov * jit/jit-rules-x86.sel: fix JIT_OP_CALL_FINALLY. 2006-02-10 Aleksey Demakov * jit/jit-bitset.c: * jit/jit-bitset.h: * jit/jit-cfg.c: * jit/jit-cfg.h: initial code drop for a more precise liveness analysis based on control flow graph. 2006-02-04 Aleksey Demakov * jit/jit-rules-x86.sel: fix a typo in JIT_OP_JUMP_TABLE. 2006-01-30 Aleksey Demakov * jit/jit-rules-x86.c (_jit_gen_load_value): optimize loading of zero constants.

Also on Win32 use TMP and TEMP environment variables as the tmp directory names and fallback to "c:/tmp". * jit/jit-gen-x86.h (jit_assert): change the macro definition to resolve problems introduced at 2005-12-10. 2005-12-10 Aleksey Demakov * jit/jit-gen-x86.h: Merged changes from the latest Mono project's version of this file. * jit/jit-rules-x86.sel: Done the following rules: JIT_OP_LOAD_ELEMENT_FLOAT32, JIT_OP_LOAD_ELEMENT_FLOAT64, JIT_OP_LOAD_ELEMENT_NFLOAT, JIT_OP_STORE_ELEMENT_LONG, JIT_OP_STORE_ELEMENT_FLOAT32, JIT_OP_STORE_ELEMENT_FLOAT64, JIT_OP_STORE_ELEMENT_NFLOAT. 2005-11-19 Klaus Treichel * jit/apply-x86-64.h: Change definition of JIT_MEMCPY from "jit_memcpy" to "jit_memcpy@PLT" to fix the build of a shared library for x86_64. 2004-11-18 Rhys Weatherley * include/jit/jit-opcode.h, jit/jit-dump.c, jit/jit-insn.c, jit/jit-interp.c, jit/jit-opcode.c, jit/jit-rules-interp.c, jit/jit-rules-x86.sel: implement tail calls properly. 2004-11-05 Evin Robertson * jit/jit-insn.c (jit_insn_store): use the destination type to determine the store opcode, not the source value type. 2004-11-02 Evin Robertson * jit/jit-function.c (jit_function_compile): clear block addresses and fixup lists if we need to restart on a new cache page (minor alterations by Rhys). * jit/jit-function.c (jit_function_apply_vararg): return 0 when a sub-function throws an exception, not 1. 2004-10-31 Rhys Weatherley * jit/jit-rules-x86.sel: handle the special case of constant destination pointers in "store_relative" instructions, because otherwise the register allocator gets confused. 2004-10-29 Peter Lund * doc/libjit.3: fix manpage formatting issues.

jitplus/jit-plus-function.cpp: clean up the breakpoint API and implement debug hooks for the interpreter. * jit/jit-insn.c, jit/jit-rules-arm.sel, jit/jit-rules-x86.sel: use a common helper function for performing debug hook tests on native platforms, to avoid the need to implement breakpoint testing individually in every native back end. 2004-09-10 Rhys Weatherley * jit/jit-rules-x86.sel: pointer-relative loads and stores for structures in the x86 back end. 2004-09-09 Rhys Weatherley * jit/jit-rules-x86.c, jit/jit-rules-x86.sel: add some support for structure copying to the x86 back end. 2004-09-06 Rhys Weatherley * jit/jit-rules-interp.c: the pointer value for indirect and vtable calls was being pushed onto the stack twice. 2004-09-05 Norbert Bollow * samples/hellovm.c: add a sample program that demonstrates a simple VM based on libjit (committed by Rhys). 2004-08-30 Rhys Weatherley * jit-rules-x86.sel: fix x86 code generation for floating-point return instructions. 2004-08-16 Rhys Weatherley * jit/jit-cpuid-x86.c (cpuid_query): use %ebx in a way that doesn't confuse PIC mode in some versions of gcc (bug #10022). 2004-08-13 Rhys Weatherley *

x86-64. * jit/jit-apply-func.h, jit/jit-apply-x86-64.h, tools/gen-apply.c: write an x86-64 assembly version of "__builtin_apply", because the version inside gcc has an unusable register ordering. 2004-06-24 Rhys Weatherley * jit/jit-reg-alloc.c, jit/jit-rules-arm.h, jit/jit-rules-interp.c, jit/jit-rules-interp.h, jit/jit-rules-x86.h, jit/jit-rules.h: use separate JIT_REG_xxx flags for float32, float64, and nfloat because some platforms need to put these values in different types of registers (e.g. x86-64). 2004-06-22 Rhys Weatherley * jit/jit-insn.c: properly set the "may_throw" flag for opcodes that throw exceptions and which are also supported by the back end. 2004-06-21 Rhys Weatherley * jit/jit-rules-x86.c, jit/jit-rules-x86.sel: move the code for loading/storing small structures

jit/jit-rules-arm.c, jit/jit-rules-arm.sel, jitplus/jit-plus-function.cpp: add support for outgoing parameter areas, which should reduce the overhead of function calls that involve stacked arguments on non-x86 platforms; use parameter areas in the ARM back end. * include/jit/jit-plus.h, include/jit/jit-value.h, jit/jit-insn.c, jit/jit-internal.h, jit/jit-reg-alloc.c, jit/jit-rules-x86.c, jit/jit-value.c: don't over-allocate x86 stack frames if EBX, ESI, and EDI don't need to be saved; don't perform global register allocation on stacked parameters because it confuses the register spill logic. * jit/jit-reg-alloc.c (_jit_regs_load_value): avoid unnecessary spills if a temporary value won't be used again in the current block. 2004-06-09 Rhys Weatherley * jit/jit-rules-arm.c
