Roberto Ierusalimschy 04587b6256 macro with empty argument can be seen as macro with no argument; better 
to avoid that
 2015-11-12 16:08:58 -02:00
Roberto Ierusalimschy bde03eeb48 in 'table.sort': tighter checks for invalid order function +

 2015-11-06 14:07:14 -02:00
Roberto Ierusalimschy 5100bc8aa1 no need for a special case to get long strings (not that common) 2015-11-03 16:35:21 -02:00
Roberto Ierusalimschy ebb2afa54b allow 'set' macros to be used when 'L' is not available (as it was

 2015-11-02 14:19:29 -02:00
Roberto Ierusalimschy 8c1fb91802 macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used 
in critical time pathes, can save a few bytes without the macro)
 2015-11-02 14:09:30 -02:00
Roberto Ierusalimschy 33b366ec32 added counters for total and individual CallInfo entries (to allow

Roberto Ierusalimschy c5363a1b58 in 'luaD_precall', in vararg functions, complete missing parameters

again)
 2015-11-02 12:06:01 -02:00

more efficient?)
 2015-11-02 09:48:59 -02:00
Roberto Ierusalimschy 07a2dcacbf flag CIST_REENTRY changed to CIST_FRESH (its negation); fresh invocations 
seem to be less frequent than reentries. (So, avoid setting flag on
the frequent case.)
 2015-11-02 09:43:17 -02:00

Roberto Ierusalimschy cc3a42b190 option 'c' in 'string.pack' accepts any string size (truncating 
if larger and padding if smaller)
 2015-10-28 15:56:51 -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 257961c601 OP_SELF can use 'luaV_fastget' specialized for strings, as it

replaced by 'Protect' (which serves this rule)
 2015-10-22 12:40:47 -02:00

 2015-10-21 16:40:47 -02:00
Roberto Ierusalimschy 48098c42ff generic definitions for float types moved to before variable definitions 
(so that specific cases can redefine these generic definitions if
needed)
 2015-10-21 16:17:40 -02:00
