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 d13a3fb070 detail 
(removed empty spaces at the end of lines)
 2017-06-09 16:16:41 -03:00
Roberto Ierusalimschy b029e7ea20 macro 'luaV_fastget' may need protection ({}) to be used inside 
'if's
 2017-06-01 17:22:33 -03:00
Roberto Ierusalimschy c25380c28d details (using proper version of 'setobj') 2017-05-23 09:50:11 -03:00
Roberto Ierusalimschy de74289049 table field names for dedicated opcodes can be restricted to 
small strings for slightly faster access
 2017-05-18 16:44:19 -03:00
Roberto Ierusalimschy 92b3deaffa details in OP_CALL + comments 2017-05-18 16:34:39 -03:00
Roberto Ierusalimschy 6d95de83c6 no more field 'base' in CallInfo (base is always equal to 'func + 1', 
with old/new vararg implementation)
 2017-05-13 10:54:47 -03:00
Roberto Ierusalimschy 5c8770f896 back to old-style vararg system (with vararg table collecting extra 
arguments)
 2017-05-13 10:04:33 -03:00
Roberto Ierusalimschy 7647d5d13d revamp of fast track for table access (table set uses the same 
macros as table get + new macro for integer keys)
 2017-05-11 15:57:46 -03:00
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 ab5a650029 details (direct access to 'Ck' bit in instructions) 2017-05-08 13:08:01 -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 
hits that fail too often
 2017-04-30 17:43:26 -03:00
Roberto Ierusalimschy 502a1d1108 new opcodes for table access with constant keys (strings and integers) 2017-04-28 17:57:45 -03:00
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
 2016-01-04 14:44:50 -02:00
Roberto Ierusalimschy c5112f7b15 details (comments) 2015-11-23 09:30:45 -02:00
Roberto Ierusalimschy d103312661 details (typos in comments) 2015-11-19 17:16:22 -02:00
Roberto Ierusalimschy 2e8f8a18e4 detail 2015-11-17 14:00:28 -02:00
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 f7670781cf cleaner definition for 'luaC_condGC', using 'pre'/'pos' parameters 2015-10-20 15:56:21 -02:00
Roberto Ierusalimschy df8b996bcc 'Protect' in table operations is not needed in the fast track 
+ removal of a few dead macros
 2015-10-20 15:41:35 -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
Roberto Ierusalimschy 3b795541c4 fast track for 'settable' 2015-08-03 16:50:49 -03:00
Roberto Ierusalimschy e247c3ada3 implementation of fast track for gettable operations 2015-07-20 15:24:50 -03:00
Roberto Ierusalimschy 319ccfefbc computations in numerical for loop must avoid overflows too 2015-07-04 13:31:03 -03:00
Roberto Ierusalimschy f01c12c891 detail (cast to avoid mixing types in conditional expression) 2015-06-25 11:00:01 -03:00
Roberto Ierusalimschy 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
 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
Roberto Ierusalimschy 0ec12c1bd1 new semantics for numerical order (following math regardless 
representation)
 2015-05-20 13:22:55 -03:00
Roberto Ierusalimschy 04ba6ea83b new semantics for equality int-float 2015-04-29 15:27:16 -03:00
Roberto Ierusalimschy ae76c39712 Bug: suspended '__le' metamethod can give wrong result 2015-04-10 14:56:25 -03:00
