Roberto Ierusalimschy	1fce5bea81	More uniform implementation for tail calls 'luaD_pretailcall' mimics 'luaD_precall', handling call metamethods and calling C functions directly. That makes the code in the interpreter loop simpler. This commit also goes back to emulating the tail call in 'luaD_precall' with a goto, as C compilers may not do proper tail calls and the C stack can overflow much sooner than the Lua stack (which grows as the metamethod is added to it).	3 years ago
Roberto Ierusalimschy	91673a8ec0	'luaD_tryfuncTM' checks stack space by itself	3 years ago
Roberto Ierusalimschy	41871f1803	Undo simplification of tail calls (commit `901d760`) Not that simpler and slower.	3 years ago
Roberto Ierusalimschy	dbdc74dc55	Simplification in the parameters of 'luaD_precall' The parameters 'nresults' and 'delta1', in 'luaD_precall', were never meaningful simultaneously. So, they were combined in a single parameter 'retdel'.	3 years ago
Roberto Ierusalimschy	901d760093	Simpler implementation for tail calls Tail calls handled by 'luaD_precall', like regular calls, to avoid code duplication.	3 years ago
Roberto Ierusalimschy	59c88f846d	Broadening the use of branch hints More uses of macros 'likely'/'unlikely' (renamed to 'l_likely'/'l_unlikely'), both in range (extended to the libraries) and in scope (extended to hooks, stack growth).	4 years ago
Roberto Ierusalimschy	7af27ef59d	Cleaner handling of errors in '__close' metamethods Instead of protecting each individual metamethod call, protect the entire call to 'luaF_close'.	4 years ago
Roberto Ierusalimschy	490d42b5f8	Correct handling of 'luaV_execute' invocations The previous stackless implementations marked all 'luaV_execute' invocations as fresh. However, re-entering 'luaV_execute' when resuming a coroutine should not be a fresh invocation. (It works because 'unroll' called 'luaV_execute' for each call entry, but it was slower than letting 'luaV_execute' finish all non-fresh invocations.)	4 years ago
Roberto Ierusalimschy	5d8ce05b3f	Back to a stackless implementation A "with stack" implementation gains too little in performance to be worth all the noise from C-stack overflows. This commit is almost a sketch, to test performance. There are several pending stuff: - review control of C-stack overflow and error messages; - what to do with setcstacklimit; - review comments; - review unroll of Lua calls.	4 years ago
Roberto Ierusalimschy	eb41999461	Fixed bugs of stack reallocation x GC Macro 'checkstackGC' was doing a GC step after resizing the stack; the GC could shrink the stack and undo the resize. Moreover, macro 'checkstackp' also does a GC step, which could remove the preallocated CallInfo when calling a function. (Its name has been changed to 'checkstackGCp' to emphasize that it calls the GC.)	4 years ago
Roberto Ierusalimschy	bd96330d03	First "complete" implementation of to-be-closed variables Still missing: - handling of memory errors when creating upvalue (must run closing method all the same) - interaction with coroutines	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
Roberto Ierusalimschy	02ed0b2c30	in 'luaD_poscall', there is no need to compute 'firstResult' when 'nres==0'	7 years ago

Roberto Ierusalimschy	0682fe8169	some simplifications/optimizations in returns from Lua functions	7 years ago
Roberto Ierusalimschy	b1379936cf	vararg back to '...' (but with another implementation) new implementation should have zero overhead for non-vararg functions	7 years ago
Roberto Ierusalimschy	51280ef2ad	call hooks for Lua functions called by 'luaV_execute'	7 years ago
Roberto Ierusalimschy	ab0a851db4	'luaD_tryfuncTM' can ensure it does not change the stack	7 years ago
Roberto Ierusalimschy	bfb88e99e9	'luaD_growstack' cannot raise any errors when 'raiseerror' is false (+ some comments)	7 years ago
Roberto Ierusalimschy	e663a24ab0	more freedom in handling memory-allocation errors (not all allocations automatically raise an error), which allows fixing a bug when resizing a table.	7 years ago
Roberto Ierusalimschy	194a4f9710	small simplifications in 'luaD_poscall'	7 years ago
Roberto Ierusalimschy	196c87c9ce	no more 'stackless' implementation; 'luaV_execute' calls itself recursively to execute function calls. 'unroll' continues all executions suspended by an yield (through a long jump)	7 years ago
Roberto Ierusalimschy	14c3aa12b5	more direct implementation for tail calls.	7 years ago
Roberto Ierusalimschy	ad0704e40c	back to 'CallInfo' (no gains with its removal)	7 years ago
Roberto Ierusalimschy	93fd67b793	no more 'CallInfo' structure	7 years ago
Roberto Ierusalimschy	f96497397a	new type 'StackValue' for stack elements (we may want to put extra info there in the future)	7 years ago

Roberto Ierusalimschy	8c1fb91802	macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used in critical time pathes, can save a few bytes without the macro)	9 years ago
Roberto Ierusalimschy	5bdee4f810	small changes to allow 'precall' to spend time preserving 'func' only when needed (that is, when stack actually changes)	9 years ago
Roberto Ierusalimschy	d39bb51faa	bug: interpreter cannot pop activation frame before calling return hook (as it may want to access local variables active by the end of the function)	10 years ago
Roberto Ierusalimschy	bdf566a8a3	`name' in comments changed to 'name'	10 years ago
