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 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 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 ae76c39712 Bug: suspended '__le' metamethod can give wrong result 2015-04-10 14:56:25 -03:00
Roberto Ierusalimschy abb2f5511d detail ('b + base' -> 'base + b' to follow all other similar uses) 2015-03-30 12:45:01 -03:00
Roberto Ierusalimschy 4ba0cb4580 always use macros to operate on lua_Numbers 2015-03-07 16:30:16 -03:00
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
'tointeger_aux'), which can do the same job.
2015-02-20 12:27:53 -02:00
Roberto Ierusalimschy c8d6cb0136 macros 'luai_num*' (for float arithmetic operations) moved to
llimits.h.

Roberto Ierusalimschy 7e2015a46d size of short strings stored in a single byte, to reduce the size
of struct 'TString'
2015-01-16 14:54:37 -02:00
Roberto Ierusalimschy 50e2eb8954 change in macro 'vmcase', avoding code inside it. (Code inside the
macro harms tools such as debuggers.)
2014-12-27 18:30:38 -02:00
Roberto Ierusalimschy 2b83711fba new macro 'nvalue' (to convert an object to a float when we know
object is a number)
2014-12-19 11:36:32 -02:00
Roberto Ierusalimschy 049cf14cf9 'x//y' extended to floats + more comments about module and floor
division operations

Roberto Ierusalimschy 5d628519d3 simpler definition for 'luaV_tonumber_' 2014-11-19 13:05:15 -02:00
Roberto Ierusalimschy bde14c3adc macro to change method of conversion from float to integer (make it
use floor intead of requiring an exact integral value)
2014-11-03 18:07:47 -02:00
Roberto Ierusalimschy 28fdbcf393 added include for 'lprefix.h', for stuff that must be added before
any other header file

Roberto Ierusalimschy 3a15c7ce43 size for array part of a table ('sizearray') changed from 'int' to
'unsigned int', which allows twice as many elements in the array part
2014-09-04 15:15:29 -03:00
Roberto Ierusalimschy d861706620 new macro 'cvt2num' to better control whether strings are convertible
to numbers
2014-07-30 11:42:44 -03:00
Roberto Ierusalimschy 34ac039fb8 new macro 'cvt2str' to better control whether numbers are convertible
to strings
2014-07-30 11:00:14 -03:00
Roberto Ierusalimschy 17ee57f8e0 'iswhite' and related macros now can work directly on any object
(no need to convert to 'GCObject')
2014-07-21 13:02:10 -03:00
Roberto Ierusalimschy ca41b43f53 type 'TString' refers directly to the structure inside the union
(union used only for size purposes)
