Roberto Ierusalimschy b95e466218 new field 'nilvalue' in struct 'global_State' to avoid the use of 
addresses of static variables
 2018-06-15 16:31:22 -03:00
Roberto Ierusalimschy 6e600695f8 field 'sizearray' in struct 'Table' changed to 'alimit', which can 
be used as a hint for '#t'
 2018-06-15 11:14:20 -03:00
Roberto Ierusalimschy 505fc91222 no more 'luaO_nilobject' to avoid comparison of global variable addresses 
(now uses static variables)
 2018-06-01 14:40:38 -03:00
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)
 2018-06-01 13:51:34 -03:00
Roberto Ierusalimschy 03c6a05ec8 no more nil-in-table 2018-04-04 11:23:41 -03:00
Roberto Ierusalimschy ef8263f81f better names for macros for tags and types. 
rttype -> rawtt; ttyperaw -> withvariant; ttype -> ttypetag;
tnov -> ttype
 2018-02-26 11:16:05 -03:00
Roberto Ierusalimschy 2952bc5fc9 special compact representation for userdata with no user values 
(a common case)
 2018-02-26 10:35:03 -03:00
Roberto Ierusalimschy 75efc6722b avoid variant tags with the same value of the original type 
(to expose bugs more easily)
 2018-02-25 09:52:32 -03:00
Roberto Ierusalimschy d766e2ae17 first (parcial) implementation of 'keyin'/'removekey' 
(still no metamethods, no raw verssions)
 2018-02-25 09:48:16 -03:00
Roberto Ierusalimschy 9243c414d9 first version of empty entries in tables 
(so that, in the future, tables can contain regular nil entries)
 2018-02-23 10:16:18 -03:00
Roberto Ierusalimschy 477ca2fe8c some reorganization in 'lobject.h' 
(just moving stuff around)
 2018-02-22 14:28:10 -03:00
Roberto Ierusalimschy c80c7a49fd details (comments) 2018-02-21 13:28:12 -03:00
Roberto Ierusalimschy ca6fe7449a userdata can have multiple user values 2018-02-20 13:52:50 -03:00
Roberto Ierusalimschy e2b15aa21d janitor work on casts 2018-01-28 13:13:26 -02:00
Roberto Ierusalimschy 6710a2b0ef detail (comment) 2018-01-28 10:07:53 -02:00
Roberto Ierusalimschy 599f1742c6 detail (typo in comments) 2017-11-23 17:29:04 -02:00
Roberto Ierusalimschy ad0704e40c back to 'CallInfo' (no gains with its removal) 2017-11-07 11:25:26 -02:00
Roberto Ierusalimschy 5a3f26f855 fitting a StackValue structure into 32 bytes (for 64-bit machines) 2017-11-06 15:34:06 -02:00
Roberto Ierusalimschy 472c560705 no more useful fields in CallInfo 2017-11-03 15:22:54 -02:00
Roberto Ierusalimschy 54eb35a8aa more fields moved out of 'CallInfo' 2017-11-03 10:12:30 -02:00
Roberto Ierusalimschy c5482468fd baby steps to remove 'CallInfo': keeping 'L->func' correct 2017-10-31 15:54:35 -02:00
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 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 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 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 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 
to the auxlib buffer
 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)
 2015-10-28 15:28:40 -02:00
Roberto Ierusalimschy ee5edb6b68 macros 'getaddrstr' and 'getstr' unified (they do the same thing) 2015-09-17 12:51:05 -03:00
Roberto Ierusalimschy eb0be12ceb detail in macro 'checkliveness' + macro 'setobj2t' defined as an 
expression (to be used in macro 'luaV_fastset')
 2015-09-08 13:54:52 -03:00
Roberto Ierusalimschy 6556fcfe5a small janitor work 2015-09-08 12:49:25 -03:00
Roberto Ierusalimschy 2ecaf18138 using macros ('rttype' and 'settt_') to access "private" field 'tt_' 2015-06-09 11:21:42 -03:00
Roberto Ierusalimschy 6ffe006f5c detail (removed unused macro VARBITS) 2015-04-02 18:10:53 -03:00
Roberto Ierusalimschy 2b37f2150e comments 2015-03-14 14:58:57 -03:00
Roberto Ierusalimschy 6408bc0b7f new macros 'chgfltvalue'/'chgivalue' (numerical for loop does 
not need to set the type of its internal variable at each iteration)
 2015-03-02 13:04:52 -03:00
Roberto Ierusalimschy 7e2015a46d size of short strings stored in a single byte, to reduce the size 
of struct 'TString'
 2015-01-16 14:54:37 -02:00
Roberto Ierusalimschy 3c55790ebe 'setkey' -> 'setnodekey' (to avoid conflicts with POSIX) 2015-01-05 11:52:37 -02:00
Roberto Ierusalimschy 2b83711fba new macro 'nvalue' (to convert an object to a float when we know 
object is a number)
 2014-12-19 11:36:32 -02:00
Roberto Ierusalimschy bdf566a8a3 `name' in comments changed to 'name' 2014-10-25 09:50:46 -02:00
Roberto Ierusalimschy 34b6664dcb better to use 'long' to represent UTF-8 code points 2014-10-01 08:52:33 -03:00
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
Roberto Ierusalimschy 34ac039fb8 new macro 'cvt2str' to better control whether numbers are convertible 
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)
