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)
 2017-07-27 10:50:16 -03:00
Roberto Ierusalimschy 11769b203f new version (5.4) 2017-07-27 10:36:54 -03:00
Roberto Ierusalimschy b1daa069ba bug: Lua does not check GC when creating error messages 2017-07-10 14:35:12 -03:00
Roberto Ierusalimschy 4dff277255 coercion string->number in arithmetic operations moved to string 
library
 2017-07-07 13:34:32 -03:00
Roberto Ierusalimschy 07db10813c 'OP_VARARG' has the vararg parameter as an operand 2017-06-29 12:38:41 -03:00
Roberto Ierusalimschy f96497397a new type 'StackValue' for stack elements 
(we may want to put extra info there in the future)
 2017-06-29 12:06:44 -03:00
Roberto Ierusalimschy 5a1c8d8ef3 new constant 'LUA_GNAME' for the name of the global table "_G" 2017-06-27 15:32:49 -03:00
Roberto Ierusalimschy 124bfd2081 dumping ints and size_ts compacted 2017-06-27 11:21:12 -03:00
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.)
 2017-06-27 08:35:31 -03:00
Roberto Ierusalimschy 60a7492d24 new type 'ls_byte' for signed bytes 2017-06-27 08:35:01 -03:00
Roberto Ierusalimschy 73ec04fcf3 no more 'DEADKEY'. Table traversals do not need to consider dead keys; 
if the key is dead, it cannot be given to 'next'. Instead, we now
use a 'table' tag without the collectable bit, which makes it
a unique tag good enough to reserve space.
 2017-06-12 11:21:44 -03:00
Roberto Ierusalimschy d13a3fb070 detail 
(removed empty spaces at the end of lines)
 2017-06-09 16:16:41 -03:00
Roberto Ierusalimschy b6f87491af in hash nodes, keys are stored in separate pieces to avoid wasting 
space with alignments
 2017-06-09 13:48:44 -03:00
Roberto Ierusalimschy 4bb30f461b when assigning to a 'TValue', better assign only exact fields, 
to allow us to put stuff after the 'TValuefields' if needed
 2017-06-01 17:24:05 -03:00
Roberto Ierusalimschy dad85e4131 macro 'setobj2t' may not be an expression 2017-06-01 17:23:27 -03:00

Roberto Ierusalimschy 8821746841 updated GC states in function 'T.gcstate' 2017-05-31 15:54:58 -03:00
Roberto Ierusalimschy 72d82a296c revamping the incremental collector 
Some simplifications (not counting bytes, couting only slots visited;
no more 'gcfinnum'); more GC parameters; using vararg in 'lua_gc' to
set parameters in different GC modes
 2017-05-26 16:14:29 -03:00
Roberto Ierusalimschy 4804bbd9bb include first standard header files 
(Some broken compiler has problems with 'signal.h' being included
without a definition for 'size_t'.)
 2017-05-24 18:11:19 -03:00
Roberto Ierusalimschy be0d951be8 bug: cannot reuse a dying upvalue 2017-05-24 15:54:54 -03:00
Roberto Ierusalimschy a9dbc2d641 assert removed in 'luaO_arith' 
(nobody calls it with L==NULL)
 2017-05-24 10:47:11 -03:00
Roberto Ierusalimschy c25380c28d details (using proper version of 'setobj') 2017-05-23 09:50:11 -03:00
Roberto Ierusalimschy 03094da80c detail (extra closing brackets) 2017-05-22 09:55:16 -03:00
Roberto Ierusalimschy 01c96ad12e handling of inf, -inf, and NaN by string.format'%q' 2017-05-19 13:29:40 -03:00
Roberto Ierusalimschy 1bdc328c75 bug: Lua crashes when building sequences with more than 2^30 elements. 
bug: Table length computation overflows for sequences larger than
2^31 elements..
 2017-05-19 09:58:40 -03:00
Roberto Ierusalimschy e3d52da144 BUG: in 'computesizes', 'twotoi' overflows when a sequence has 
more than 2^30 elements.
 2017-05-19 09:57:10 -03:00
Roberto Ierusalimschy e39ee2cc58 'luaH_getn' must return 'lua_Unsigned' (or 'lua_Integer'), to 
allow the boundary-search algorithm to use 'maxinteger' when
it cannot find a good upper bound.
 2017-05-19 09:48:15 -03:00
Roberto Ierusalimschy 84910e04e2 better implementation for 'hash_search', without using 'size_t' 
(simpler to implement and to explain)
 2017-05-19 09:47:00 -03:00
Roberto Ierusalimschy de74289049 table field names for dedicated opcodes can be restricted to 
small strings for slightly faster access
 2017-05-18 16:44:19 -03:00
Roberto Ierusalimschy 92b3deaffa details in OP_CALL + comments 2017-05-18 16:34:39 -03:00
Roberto Ierusalimschy 49f7aab62a 'lua_rawlen' returns 'lua_Unsigned' instead of 'size_t'. (Real 
length of strings and userdata are limited by Lua integers,
but table length is hard to compute limiting it to 'size_t'.)
 2017-05-18 09:34:58 -03:00
Roberto Ierusalimschy 3d879fbc5d reimplementation of 'luaH_getn', trying to handle numeric limits 
properly.
 2017-05-16 16:07:08 -03:00

 2017-05-13 10:54:47 -03:00

Roberto Ierusalimschy e8757a73e6 'luaV_execute' keeps local copy of program counter and hook mask, 
to avoid excessive access to globals.
 2017-05-05 14:16:11 -03:00

 2017-05-04 10:32:01 -03:00
Roberto Ierusalimschy 8634b2a011 added 'cachemiss' field to prototype to avoid wasting time checking 
hits that fail too often

Roberto Ierusalimschy 7fe1a4cff3 cleaner and more correct code for 'luaD_shrinkstack' (the old

 2016-09-08 13:36:26 -03:00
Roberto Ierusalimschy dbb6f11e8e bug (with compat on): 'ipairs' can work with any type that provides
