TclDecrRefCount macros. The different + instructions now jump back to a common "DecrRefCount zone" at + the top of the loop. The macro "ADJUST_PC" was replaced by two + macros "NEXT_INST_F" and "NEXT_INST_V" that take three params + (pcAdjustment, # of stack objects to discard, resultObjPtr + handling flag). The only instructions that retain a + TclDecrRefCount are INST_POP (for speed), the common code for + the non-immediate INST_INCR, INST_FOREACH_STEP and the two + INST_LSET. + + The object size of tclExecute.o was reduced by approx 20% since + the start of the consolidation drive, while making room for some + peep-hole optimisation at runtime. + +2002-06-18 Miguel Sofer <msofer@users.sourceforge.net> + * generic/tclExecute.c (TEBC, INST_DONE): small bug in the panic code for tcl-stack corruption. |
