Tue Nov 30 12:36:15 1999 Anthony Green <green@cygnus.com> * verify.c (verify_jvm_instructions): Create new return label chain if non existant (don't rely on the verified state of the jsr target.) Tue Nov 23 17:29:40 1999 Alexandre Petit-Bianco <apbianco@cygnus.com> * verify.c (merge_type_state): Non verified subroutines being considered more than once to trigger passive type merge.
