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.

Roberto Ierusalimschy b6f87491af in hash nodes, keys are stored in separate pieces to avoid wasting
space with alignments

Roberto Ierusalimschy 4bb30f461b when assigning to a 'TValue', better assign only exact fields,

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

Roberto Ierusalimschy 1bdc328c75 bug: Lua crashes when building sequences with more than 2^30 elements.

2^31 elements..

Roberto Ierusalimschy e3d52da144 BUG: in 'computesizes', 'twotoi' overflows when a sequence has

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'

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'.)
