annotate src/bytecode.c @ 1626:5cec7ab01719

[xemacs-hg @ 2003-08-16 14:18:36 by michaels] 2003-08-12 Mike Sperber <mike@xemacs.org> * bytecode.c (GCPRO_STACK): Added. (execute_optimized_program): Use GCPRO_STACK, fixing a space leak: Formerly, the byte-code engine would always hold on to the entire stack memory area, including the stuff above the top. Now, we adjust the GCPRO record via GCPRO_STACK just before a GC may occur.
