Roberto Ierusalimschy 7184f6343a more integer fast tracks (for OP_LT, OP_LE, OP_SETTABLE, and OP_GETTABLE) 2017-05-10 14:32:19 -03:00

Roberto Ierusalimschy e8757a73e6 'luaV_execute' keeps local copy of program counter and hook mask,
to avoid excessive access to globals.
2017-05-05 14:16:11 -03:00
Roberto Ierusalimschy 2376eb6347 barrier for prototype's cache (with new gray list 'protogray' to keep
prototypes to have their caches visited again) + constant 'MAXMISS'
2017-05-04 10:32:01 -03:00
Roberto Ierusalimschy 8634b2a011 added 'cachemiss' field to prototype to avoid wasting time checking

Roberto Ierusalimschy 173e41b2eb new opcode OP_ADDI (for immediate integer operand) (Experimental) 2017-04-26 14:46:52 -03:00
Roberto Ierusalimschy cb3d5dce30 opcodes 'OP_GETTABUP'/'OP_SETTABUP' operate only with string keys,
so they can use fast-track table access
2017-04-24 17:26:39 -03:00
Roberto Ierusalimschy 6a98aa0bb0 new opcode LOADI (for loading immediate integers) 2017-04-20 16:53:55 -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 2331e1beec small changes in 'luaC_upvalbarrier' 2017-04-06 10:08:56 -03:00
Roberto Ierusalimschy fd51651684 new macro 'vmfetch' to help changing code to computed goto's (macro
abstracts the code to run before each instruction)
2016-02-05 17:59:14 -02:00
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 a272fa66f0 bug: Metatable may access its own dealocated field when
it has a self reference in __newindex + some refactoring

Roberto Ierusalimschy 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
Roberto Ierusalimschy 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
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 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)
2015-10-22 12:40:47 -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 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
Roberto Ierusalimschy 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)
2015-09-08 12:41:05 -03:00
Roberto Ierusalimschy 8f25d08637 'invalidateTMcache' not needed in all 'settable' uses 2015-08-03 17:40:26 -03:00

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
2015-06-02 16:11:24 -03:00
Roberto Ierusalimschy 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)
2015-05-20 15:19:11 -03:00

representation)

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