* jit-insn.c, jit-insn.h, jit-function.c, jit-function.h, jit-internal.h:
implement nesting using retrieve_frame_pointer and the frame_offset of
values. The frame pointer can either be passed automatically to child
functions when e.g. using jit_insn_call or manually using the new
functions jit_insn_call_nested_indirect, jit_insn_get_frame_pointer,
jit_insn_get_parent_frame_pointer_of or jit_function_set_parent_frame.

JIT_OP_INCOMING_REG and JIT_OP_RETURN_REG instructions so it can
free unused values on these instructions rather than on the block
end.

to correctly spill the old register value at this point so do not
attempt this and do not promise this.
2008-05-04 Klaus Treichel <ktreichel@web.de>

replace common_binary() with more basic function calls that should
suffice.

false for non-floating point values and do not use common_binary()
as well.

file.
2008-01-16 Klaus Treichel <ktreichel@web.de>
* jit/jit-gen-x86.h: Use the supplied base register instead of

2007-12-16 Klaus Treichel <ktreichel@web.de>
* configure.in: Add support for multi os archs (like x86_64). Put the
libraries in the correct directories so that 32- and 64-bit code doesn't
get mixed up.
* jit/jit-apply-x86-64.h: Add some information about the clobber list to
jit_builtin_apply and add r10 and r11 to the clobber list because they
are not preserved by the callee and we call arbitrary functions here.
* jit/jit-internal.h: Cast _JIT_ALIGN_TO_TYPE to jit_nuint instead of
unsigned because jit_nuint is guaranteed to have the size of a pointer.
This fixes compiler warnings on x86_64 too.

function that should finally optimize relative instructions
correctly.
2007-06-10 Aleksey Demakov <ademakov@gmail.com>

(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 <ktreichel@web.de>
* jit/jit-intrinsic.c: Fix conversion from ulong to nfloat for values
greater that jit_max_long.
2007-05-26 Aleksey Demakov <ademakov@gmail.com>
* 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 <ademakov@gmail.com>

2007-02-25 Aleksey Demakov <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* jit/jit-function.c (compile_block): check if cache is full and
exit if so.
2007-02-13 Aleksey Demakov <ademakov@gmail.com>
* 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

* 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 <ktreichel@web.de>
* jit/jit-function.c: Use the on-demand compilation driver in
jit_function_apply too. Return the functions' entry point if the

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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>

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.

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 <ademakov@gmail.com>
* jit/jit-reg-alloc.c (exch_stack_top, free_value): fix freeing
stack registers.
2006-11-25 Kirill Kononenko <Kirill.Kononenko@gmail.com>
* 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 <ademakov@gmail.com>
* jit/jit-rules-x86.ins: add JIT_OP_IABS and JIT_OP_LABS rules.
2006-11-04 Aleksey Demakov <ademakov@gmail.com>
* jit/jit-rules-x86.ins: make comparison opcodes use three-address
patterns.
2006-11-01 Aleksey Demakov <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ktreichel@web.de>
* jit/jit-intrinsic.c: Fix a copy bug in jit_ulong_mul (replace - by *).
2006-09-25 Aleksey Demakov <ademakov@gmail.com>
* 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 <psonek2@seznam.cz>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ktreichel@web.de>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ktreichel@web.de>
* dpas/Makefile.am, jit/Makefile.am, tests/Makefile.am: Add missing
sources to fix creation of tarballs (make dist).
2006-08-25 Yan Burman <yan_952@hotmail.com>
* jitdynamic/jit-cpp-mangle.c (mangle_type_gcc3): fix typo in
is_unsigned usage (patch #5324)
2006-08-23 Thomas Cort <linuxgeek@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <Kirill.Kononenko@gmail.com>].
* 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 <ktreichel@web.de>
* 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 <linuxgeek@gmail.com>
* 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 <linuxgeek@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <linuxgeek@gmail.com>
* 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 <Kirill.Kononenko@gmail.com>
* 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 <linuxgeek@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <linuxgeek@gmail.com>
* 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 <linuxgeek@gmail.com>
* 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 <linuxgeek@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <linuxgeek@gmail.com>
* 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 <ademakov@gmail.com>
* jit/jit-rules-x86.ins: fix division by power of two.
2006-07-05 Aleksey Demakov <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ktreichel@web.de>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* jit/jit-reg-alloc.h, jit/jit-reg-alloc.c: fix spilling and many
problems with stack registers.
2006-05-04 Radek Polak <psonek2@seznam.cz>
* jit/jit-dump.c (dump_object_code): Now can dump to any stream
not just stdout and stderr.
2006-05-01 Aleksey Demakov <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* tools/gen-rules-parser.y: fix generation of `if' pattern code.
2006-04-19 Aleksey Demakov <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* 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 <ademakov@gmail.com>
* jit/jit-insn.c (jit_insn_start_catcher): initialize
thrown_exception (the problem was found by Klaus).
2006-04-08 Aleksey Demakov <ademakov@gmail.com>
* 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 <ktreichel@web.de>
* jit/jit-internal.h (struct _jit_function): add indirector field.
* jit/jit-function.c (jit_function_compile, jit_function_create):
