Roberto Ierusalimschy	ae5b5ba529	Fixed bug: line hooks in stripped functions Line-hook handling was accessing debug info. without checking whether it was present.	4 years ago
Roberto Ierusalimschy	a585eae6e7	Fixed bug: Negation overflow in getlocal/setlocal	4 years ago
Roberto Ierusalimschy	a2195644d8	Fixed bug: invalid 'oldpc' when returning to a function The field 'L->oldpc' is not always updated when control returns to a function; an invalid value can seg. fault when computing 'changedline'. (One example is an error in a finalizer; control can return to 'luaV_execute' without executing 'luaD_poscall'.) Instead of trying to fix all possible corner cases, it seems safer to be resilient to invalid values for 'oldpc'. Valid but wrong values at most cause an extra call to a line hook.	4 years ago
Roberto Ierusalimschy	17dbaa8639	Improvements in the handling of signals Added 'volatile' to 'l_signalT' variables plus some minor changes.	5 years ago
Roberto Ierusalimschy	6eb53b7526	Details Several details in code (e.g., moving a variable to the most inner scope that encloses its uses), comments, parameter names, extra tests.	5 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	5ff408d218	Changed internal representation of booleans Instead of an explicit value (field 'b'), true and false use different tag variants. This avoids reading an extra field and results in more direct code. (Most code that uses booleans needs to distinguish between true and false anyway.)	5 years ago
Roberto Ierusalimschy	4518e5df24	Added macro 'testMMMode' Macro 'testMMMode' checks whether opcode is an MM opcode.	5 years ago
Roberto Ierusalimschy	46b84580d6	Use of 'MMBIN' opcodes extended to shift operators Plus, this commit removes useless 'tm' parameters in 'op_*' macros.	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	fe040633a1	Tracebacks recognize metamethods '__close'	5 years ago
Roberto Ierusalimschy	2c68e66570	Details Several small changes from feedback on 5.4 alhpa rc1 (warnings, typos in the manual, and the like)	6 years ago
Roberto Ierusalimschy	5ca1075b71	Added field 'srclen' to structure 'lua_Debug' This new field gets the length of 'source' in the same structure. Unlike the other strings in that structure, 'source' can be relatively large, and Lua already has its length readily available.	6 years ago
Roberto Ierusalimschy	6d04537ea6	A to-be-closed variable must have a closable value (or be nil) It is an error for a to-be-closed variable to have a non-closable non-nil value when it is being closed. This situation does not seem to be useful and often hints to an error. (Particularly in the C API, it is easy to change a to-be-closed index by mistake.)	6 years ago
Roberto Ierusalimschy	84e32ad2eb	Added opcodes for arithmetic with K operands Added opcodes for all seven arithmetic operators with K operands (that is, operands that are numbers in the array of constants of the function). They cover the cases of constant float operands (e.g., 'x + .0.0', 'x^0.5') and large integer operands (e.g., 'x % 10000').	6 years ago
Roberto Ierusalimschy	e073cbc2e5	Better error messages for invalid operands in numeric 'for' "Better" and similar to error messages for invalid function arguments. old message: 'for' limit must be a number new message: bad 'for' limit (number expected, got table)	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	6f2b8e21c4	added 'const' to 'Proto*' when possible	7 years ago
Roberto Ierusalimschy	e64e20ac81	minimizing the code ran by 'vmfetch' + no more 'vra' (the code is simpler without 'vra' and conversion is a no-op)	7 years ago
Roberto Ierusalimschy	4907444db9	'fTransfer' -> 'ftransfer' / 'nTransfer' -> 'ntransfer' (keep the standard of names in lower case)	7 years ago
Roberto Ierusalimschy	422318f677	two new fields 'fTransfer'/'nTransfer' in 'lua_Debug' structure (for information about values being given and returned in function calls)	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	728ff94595	error handler in protected calls must be a function	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	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	9fa1baf6de	opcodes for order and shift can use several metamethods, so it is better to use a generic description + metamethod names in some error messages shown without '__' prefix	7 years ago
Roberto Ierusalimschy	599f1742c6	detail (typo in comments)	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	5440b42f43	using 'trap' to stop 'luaV_execute' when necessary (tracing and to update its copy of 'base' when the stack is reallocated)	7 years ago
Roberto Ierusalimschy	62f3b7c472	detail	7 years ago
Roberto Ierusalimschy	26679ea35b	new function 'luaV_flttointeger' to convert floats to integers (without string coercions) + string operands to bitwise operations handled by string metamethods	7 years ago
Roberto Ierusalimschy	c3e5946fb2	new format for JUMP instructions (to allow larger offsets)	7 years ago
Roberto Ierusalimschy	ad0704e40c	back to 'CallInfo' (no gains with its removal)	7 years ago
Roberto Ierusalimschy	6bb3e40a8d	'lua_Debug' not using 'CallInfo'	7 years ago
Roberto Ierusalimschy	7612f7735d	removing uses of 'CallInfo'	7 years ago
Roberto Ierusalimschy	472c560705	no more useful fields in CallInfo	7 years ago
Roberto Ierusalimschy	54eb35a8aa	more fields moved out of 'CallInfo'	7 years ago
Roberto Ierusalimschy	ba36180fd7	new API for 'lua_resume' + cleaning the uses of the 'extra' field in 'CallInfo'	7 years ago
Roberto Ierusalimschy	b9e76be8a6	using 'L->func' when possible	7 years ago
Roberto Ierusalimschy	ad5dcdcf0f	detail: in 'isinstack', check against the whole stack instead of against the stack frame	7 years ago
Roberto Ierusalimschy	a1ef58b3a5	eplicit 1-bit opcode operand 'k'	7 years ago
Roberto Ierusalimschy	8fbe9e3470	new opcodes with immediate integer operand for all arithmetic operations	7 years ago
Roberto Ierusalimschy	b1daa069ba	bug: Lua does not check GC when creating error messages	7 years ago
Roberto Ierusalimschy	4dff277255	coercion string->number in arithmetic operations moved to string library	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	b42430fd3a	'lineinfo' in prototypes saved as differences instead of absolute values, so that the array can use bytes instead of ints, reducing its size. (A new array 'abslineinfo' is used when line differences do not fit in a byte.)	7 years ago
Roberto Ierusalimschy	6d95de83c6	no more field 'base' in CallInfo (base is always equal to 'func + 1', with old/new vararg implementation)	8 years ago
