Author	SHA1	Message	Date
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	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	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	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	b43300c14f	change in 'LUAI_DDEC' to allow variables to be static in 'onelua' + change in 'LUAMOD_API' as opening functions do not need to be global	6 years ago
Roberto Ierusalimschy	6f2b8e21c4	added 'const' to 'Proto*' when possible	7 years ago
Roberto Ierusalimschy	fb8fa66136	no more 'luaH_emptyobject' and comparisons of addresses of global variables (instead, use a different kind of nil to signal the fake entry returned when a key is not found in a table)	7 years ago
Roberto Ierusalimschy	892aff2a07	avoid circular inclusion between ltm.h <-> lstate.h	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	49dae52d08	correct way to check stack space for vararg 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	318a9a5859	new opcode 'PREPVARARG' (avoids test for vararg function in all function calls)	7 years ago
Roberto Ierusalimschy	89110986d7	bug in tailcall of vararg functions (when adjusting missing parameters)	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	093c16b67b	new opcodes 'OP_LTI' and 'OP_LEI'	7 years ago
Roberto Ierusalimschy	1b10033583	new function 'luaT_trybiniTM' to handle tag methods for instructions with immediate integer arguments	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	5c8770f896	back to old-style vararg system (with vararg table collecting extra arguments)	8 years ago
Roberto Ierusalimschy	fb9de1b4d7	detail ('luaT_callbinTM' does not need to be extern)	8 years ago
