4053eae9eb bug: Lua does not check GC when creating error messages 2017-07-27 10:55:38 -03:00
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)

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.)

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.

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

4804bbd9bb include first standard header files

without a definition for 'size_t'.)

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.

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'.)
