fd51651684 new macro 'vmfetch' to help changing code to computed goto's (macro 
abstracts the code to run before each instruction)

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)

9a5d6aedb7 trying to optimize a little 'luaD_poscall' 2015-11-13 11:24:26 -02:00
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

ff1289a361 in 'luaD_call', use two functions instead of one with fixed boolean 
argument
 2015-11-02 16:48:07 -02:00
Roberto Ierusalimschy
c5363a1b58 in 'luaD_precall', in vararg functions, complete missing parameters 
only after moving them to final place (avoids checking the stack
again)
 2015-11-02 12:06:01 -02:00

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.)

257961c601 OP_SELF can use 'luaV_fastget' specialized for strings, as it 
is applied only to string keys
 2015-10-28 12:50:09 -02:00
Roberto Ierusalimschy
8004ab756f hook test in 'luaV_execute' reduced to minimum (rest done in 
'luaG_traceexec'; no difference in performance for the non-hook
case, but keeps 'luaV_execute' a little simpler) + 'base' updates
replaced by 'Protect' (which serves this rule)

ee5edb6b68 macros 'getaddrstr' and 'getstr' unified (they do the same thing) 2015-09-17 12:51:05 -03:00
Roberto Ierusalimschy
b91bc93fd3 'setobj2t' incorporated into 'luaV_fastset' + 'invalidateTMcache' 
is not needed in the fast track (as it does not create new
entries)
 2015-09-09 10:44:07 -03:00

41964648ee long strings are created directly in final position when possible 
(instead of using an auxiliar buffer to first create the string
and then allocate the final string and copy result there)

a1415c0d72 bug in order NaN x int (tests must ensure that NaN does not get 
converted to integer)
 2015-06-09 12:53:35 -03:00
Roberto Ierusalimschy
ed1fe28bb8 When comparing integers with floats, use float as common type when 
possible (i.e., when integer fits in a float without losses); seems
to be more efficient in architectures with native support for used
Lua numbers

d39bb51faa bug: interpreter cannot pop activation frame before calling return 
hook (as it may want to access local variables active by the end
of the function)
 2015-05-22 14:48:19 -03:00
Roberto Ierusalimschy
6dc20ff293 'l <= r' for numbers has its own function, instead of using 
'not (r < l)' (seems to be slightly more efficient)

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

81245b1ad5 'numisinteger' (for table keys) replaced by 'luaV_tointeger' (old

50e2eb8954 change in macro 'vmcase', avoding code inside it. (Code inside the
