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
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

Roberto Ierusalimschy 8634b2a011 added 'cachemiss' field to prototype to avoid wasting time checking
hits that fail too often
2017-04-30 17:43:26 -03:00
Roberto Ierusalimschy 2caecf1b3e type 'L_Umaxalign' replaced by macro 'LUAI_MAXALIGN', which is also added

2017-04-24 15:06:12 -03:00
Roberto Ierusalimschy a3d36fe283 Upvalues collected like everything else (with mark-sweep) instead
of reference count (simpler and better for generational mode)
2017-04-11 15:41:09 -03:00
Roberto Ierusalimschy e4a9e6fcca do not eliminate varargs from functions that do not use varargs
(confuses the debug lib and gains very little in performance)
2016-08-01 16:51:24 -03:00
Roberto Ierusalimschy ebb2afa54b allow 'set' macros to be used when 'L' is not available (as it was
needed only for assertions)
2015-11-03 16:33:10 -02:00
Roberto Ierusalimschy 6707ce6349 function prepares vararg only if it really uses them (chunks
are always declared vararg but seldom uses them)

Roberto Ierusalimschy 6408bc0b7f new macros 'chgfltvalue'/'chgivalue' (numerical for loop does
not need to set the type of its internal variable at each iteration)

Roberto Ierusalimschy 3a15c7ce43 size for array part of a table ('sizearray') changed from 'int' to
'unsigned int', which allows twice as many elements in the array part
2014-09-04 15:15:29 -03:00

to strings
2014-07-30 11:00:14 -03:00
Roberto Ierusalimschy 07c7fdb9df simpler definition for 'setobj' (trust the compiler for the assignment) 2014-07-29 13:22:24 -03:00
Roberto Ierusalimschy bb12903120 type 'Udata' refers directly to structure inside the union (union
used only for aligning purposes now)
2014-07-18 11:46:47 -03:00
Roberto Ierusalimschy ca41b43f53 type 'TString' refers directly to the structure inside the union
(union used only for size purposes)
2014-07-18 10:36:14 -03:00
Roberto Ierusalimschy 56137d58ff added check for conversion 'obj2gco' (and corrections for small
problems detected by this check)
2014-07-18 09:17:54 -03:00
Roberto Ierusalimschy 9aec500a26 no need for field 'gch' anymore 2014-07-17 14:27:49 -03:00
Roberto Ierusalimschy 5a9cc57a5e change in GCObject: instead of being a union, it is now a structure
with the common header of all collectable objects; union is used
only for conversions. (Goal is to be able to check that the cast
'obj2gco' can have a check to ensure that object being converted
is really a collectable object.). This is the first step in the
change.
2014-07-17 14:09:50 -03:00
Roberto Ierusalimschy 0e6229a953 use proper macros to convert 'GCObject' to other objects + better

2014-05-01 15:18:06 -03:00
Roberto Ierusalimschy 5388aa9fc0 'luaO_str2d' + 'luaO_str2int' replaced by 'luaO_str2num' (which converts

Roberto Ierusalimschy fa6ea831b3 macro 'nvalue' removed (direct conversion from integer to double,
