Roberto Ierusalimschy 789e423b32 corrected comparisons of signed (int) with unsigned (size_t) 2015-10-29 13:11:41 -02:00
Roberto Ierusalimschy 96ec8671b1 macro 'buff2num' replaced by its body (it caused more harm than good 
to readability)
 2015-10-28 16:51:47 -02:00
Roberto Ierusalimschy cc3a42b190 option 'c' in 'string.pack' accepts any string size (truncating 
if larger and padding if smaller)
 2015-10-28 15:56:51 -02:00
Roberto Ierusalimschy 6707ce6349 function prepares vararg only if it really uses them (chunks 
are always declared vararg but seldom uses them)
 2015-10-28 15:28:40 -02:00
Roberto Ierusalimschy 257961c601 OP_SELF can use 'luaV_fastget' specialized for strings, as it

two roles)

Roberto Ierusalimschy 82129b9266 use macro 'hasjumps' to test whether expression has jumps... 2015-10-26 12:27:47 -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 ee5ef0f295 hook test in 'luaV_execute' reduced to minimum (rest done in

 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)

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 75d5a8924c macro 'addbuff' was using external variable name, instead of using 
its parameter name inside the macro.
 2015-10-20 11:11:05 -02:00
Roberto Ierusalimschy 880f82d089 '*' as a number means stack size, so that "return *" returns 
all values in the stack.

Roberto Ierusalimschy bda83e22c0 'tablib' does not try to use raw operations when possible: fast 
track should make standard operations fast enough to forgo
raw accesses
 2015-09-09 12:42:30 -03:00
Roberto Ierusalimschy 364cdbdbdb 'setobj2t' incorporated into 'luaV_fastset' + 'invalidateTMcache' 
is not needed in the fast track (as it does not create new
entries) + small bug in 'auxsetstr' (calling barrier with wrong
object) + using 'setobj2t' without side effects in its arguments
 2015-09-09 10:45:50 -03:00
Roberto Ierusalimschy b91bc93fd3 'setobj2t' incorporated into 'luaV_fastset' + 'invalidateTMcache'

Roberto Ierusalimschy 41964648ee long strings are created directly in final position when possible

and then allocate the final string and copy result there)
 2015-09-08 12:41:05 -03:00
Roberto Ierusalimschy 502214f8a5 added assert for NULL pointer in 'lua_pushlstring' 2015-08-25 15:50:37 -03:00
