Roberto Ierusalimschy	0acd55898d	Added gcc option '-Wconversion' No warnings for standard numerical types. Still pending alternative numerical types.	3 months ago
Roberto Ierusalimschy	88a50ffa71	Fixed dangling 'StkId' in 'luaV_finishget' Bug introduced in `05932567`.	7 months ago
Roberto Ierusalimschy	c31d6774ac	Details	9 months ago
Roberto Ierusalimschy	819bd51d87	Some cleaning in the new table API	2 years ago
Roberto Ierusalimschy	152b51955a	Removed GC checks from function calls Function calls do not create new objects. (It may use memory with stack reallocation, but now that is irrelevant to the GC.)	2 years ago
Roberto Ierusalimschy	413a393e62	Stack indices changed to union's That will allow to change pointers to offsets while reallocating the stack.	2 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	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	46c3587a6f	Clearer distinction between types and tags LUA_T* represents only types; tags (types + Variants) are represented by LUA_V* constants.	5 years ago
Roberto Ierusalimschy	1e0ad018ce	Comment about LUA_COMPAT_LT_LE moved to proper place	5 years ago
Roberto Ierusalimschy	72a094bda7	Undo change in the handling of 'L->top' (commit `b80077b8f3`) With MMBIN instructions, there are fewer opcodes that need to update 'L->top', so that change does not seem to pay for the increased complexity.	5 years ago
Roberto Ierusalimschy	df13f25948	First version of OP_MMBIN opcodes In arithmetic/bitwise operators, the call to metamethods is made in a separate opcode following the main one. (The main opcode skips this next one when the operation succeeds.) This change reduces slightly the size of the binary and the complexity of the arithmetic/bitwise opcodes. It also simplfies the treatment of errors and yeld/resume in these operations, as there are much fewer cases to consider. (Only OP_MMBIN/OP_MMBINI/OP_MMBINK, instead of all variants of all arithmetic/bitwise operators.)	5 years ago
Roberto Ierusalimschy	b80077b8f3	Change in the handling of 'L->top' when calling metamethods Instead of updating 'L->top' in every place that may call a metamethod, the metamethod functions themselves (luaT_trybinTM and luaT_callorderTM) correct the top. (When calling metamethods from the C API, however, the callers must preserve 'L->top'.)	5 years ago
Roberto Ierusalimschy	e888976bc6	Details (typos in comments)	5 years ago
Roberto Ierusalimschy	23e6bac8a0	Keep correct type for immediate operands in comparisons When calling metamethods for things like 'a < 3.0', which generates the opcode OP_LTI, the C register tells that the operand was converted to an integer, so that it can be corrected to float when calling a metamethod. This commit also includes some other stuff: - file 'onelua.c' added to the project - opcode OP_PREPVARARG renamed to OP_VARARGPREP - comparison opcodes rewritten through macros	6 years ago
Roberto Ierusalimschy	5e76a4fd31	New macros for arithmetic/bitwise operations in 'luaV_execute' The repetitive code of the arithmetic and bitwise operators in the main iterpreter loop was moved to appropriate macros. (As a detail, the function 'luaV_div' was renamed 'luaV_idiv', as it does an "integer division" (floor division).	6 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	8c8a91f2ef	Deprecated the emulation of '__le' using '__lt' As hinted in the manual for Lua 5.3, the emulation of the metamethod for '__le' using '__le' has been deprecated. It is slow, complicates the logic, and it is easy to avoid this emulation by defining a proper '__le' function. Moreover, often this emulation was used wrongly, with a programmer assuming that an order is total when it is not (e.g., NaN in floating-point numbers).	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	b95e466218	new field 'nilvalue' in struct 'global_State' to avoid the use of addresses of static variables	6 years ago
Roberto Ierusalimschy	6f2b8e21c4	added 'const' to 'Proto*' when possible	7 years ago
Roberto Ierusalimschy	505fc91222	no more 'luaO_nilobject' to avoid comparison of global variable addresses (now uses static variables)	7 years ago
Roberto Ierusalimschy	03c6a05ec8	no more nil-in-table	7 years ago
Roberto Ierusalimschy	b7edf5d2d8	metamethods for 'removekey'/'keyin'	7 years ago

Roberto Ierusalimschy	9243c414d9	first version of empty entries in tables (so that, in the future, tables can contain regular nil entries)	7 years ago

Roberto Ierusalimschy	89110986d7	bug in tailcall of vararg functions (when adjusting missing parameters)	7 years ago
Roberto Ierusalimschy	53979dfe0d	calling a vararg function needs to check GC (because it creates a new table)	7 years ago
Roberto Ierusalimschy	cf7eff45f3	keep control of stack top in Lua functions concentrated in 'luaV_execute'	7 years ago
Roberto Ierusalimschy	1d5b885437	when running Lua code, there is no need to keep 'L->top' "correct"; set it only when needed.	7 years ago
Roberto Ierusalimschy	4dc0be950a	new macro 'isLuacode' (to distinguish regular Lua code from hooks, where C code can run inside a Lua function).	7 years ago
Roberto Ierusalimschy	b3f924bc69	'Proto->numparams' does not include vararg parameter (one less subtraction when calling functions...)	7 years ago
Roberto Ierusalimschy	86431a2f1c	new opcodes BANDK/BORK/BXORK. (They do not use immediate operands because, too often, masks in bitwise operations are integers larger than one byte.)	7 years ago
Roberto Ierusalimschy	ac78b914b6	warnings from Visual Studio /W3	7 years ago
Roberto Ierusalimschy	093c16b67b	new opcodes 'OP_LTI' and 'OP_LEI'	7 years ago

Roberto Ierusalimschy	6d998055c8	no more reference 'memerrmsg' + new reference to "n" (both can be retrieved by 'luaS_newliteral' without creating anything, because they are fixed, but "n" deserves fast access while 'memerrmsg' does not)	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
