Roberto Ierusalimschy 8d4feb504f do not try to ensure that 'sweepgc' points to a live object 
when entering sweep phase ('entersweep'); that may be too
expensive to be done still inside the atomic step. Walking
one single object more often than not will work.

Roberto Ierusalimschy acff3ad88d bug: 'gmatch' iterator fails when called from a coroutine different 
from the one that created it

Roberto Ierusalimschy e7b2e01d43 bug: label between local definitions can mix-up their initializations 2016-03-07 16:25:39 -03:00
Roberto Ierusalimschy 03ca6385dc call 'checkGC' *after* creating new objects (this is how 'execute' 
does it)
(It increases the changes that 'allgc' start with a non-white
object, which helps 'entersweep')

 2016-02-08 10:55:19 -02:00
Roberto Ierusalimschy fd51651684 new macro 'vmfetch' to help changing code to computed goto's (macro

Roberto Ierusalimschy 62f6652d53 no more extra space in 'luaL_checkstack'. (It was already useless 
for the first call, and function works ok without that space
anyway (just error message misses the 'msg' component)

Roberto Ierusalimschy 1a44e82200 'luaV_fastget' only treats the real fast case (table with a non-nil 
value at given key, so that it does not need to check metamethods)
 2016-01-05 14:07:21 -02:00

Roberto Ierusalimschy bda090b961 comments + small code changes around stack usage when 'luaL_checkstack' 
raises an error (and needs the stack to create the error message...)
 2015-12-14 09:59:27 -02:00
Roberto Ierusalimschy e383941652 in 'table.sort': 'typedef' for type of indices + removed stack check

 2015-11-02 14:19:29 -02:00
Roberto Ierusalimschy 8c1fb91802 macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used

 2015-11-02 14:09:30 -02:00
Roberto Ierusalimschy 33b366ec32 added counters for total and individual CallInfo entries (to allow

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.)

Roberto Ierusalimschy 6707ce6349 function prepares vararg only if it really uses them (chunks 
are always declared vararg but seldom uses them)

Roberto Ierusalimschy 8004ab756f hook test in 'luaV_execute' reduced to minimum (rest done in

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

Roberto Ierusalimschy 5bdee4f810 small changes to allow 'precall' to spend time preserving 'func' 
only when needed (that is, when stack actually changes)
 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
Roberto Ierusalimschy 3ad55386c4 'condchangemem' also may need to run 'pre'/'pos' 2015-10-21 16:15:15 -02:00
