  • 8c1fb91802 macro 'incr_top' replaced by function 'luaD_inctop'. (It is not used in critical time pathes, can save a few bytes without the macro) Roberto Ierusalimschy 2015-11-02 14:09:30 -02:00
  • 33b366ec32 added counters for total and individual CallInfo entries (to allow better syncronization between CallInfo size and stack size) Roberto Ierusalimschy 2015-11-02 14:01:41 -02:00

  • 257961c601 OP_SELF can use 'luaV_fastget' specialized for strings, as it is applied only to string keys Roberto Ierusalimschy 2015-10-28 12:50:09 -02:00

  • 48098c42ff generic definitions for float types moved to before variable definitions (so that specific cases can redefine these generic definitions if needed) Roberto Ierusalimschy 2015-10-21 16:17:40 -02:00
  • 3ad55386c4 'condchangemem' also may need to run 'pre'/'pos' Roberto Ierusalimschy 2015-10-21 16:15:15 -02:00

  • 75d5a8924c macro 'addbuff' was using external variable name, instead of using its parameter name inside the macro. Roberto Ierusalimschy 2015-10-20 11:11:05 -02:00
  • 880f82d089 '*' as a number means stack size, so that "return *" returns all values in the stack. Roberto Ierusalimschy 2015-10-12 13:38:19 -03:00

  • 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 Roberto Ierusalimschy 2015-09-09 10:45:50 -03:00
