Handle multiple references to the TRAP block. Handle non-adjacent THEN and OTHER blocks. 2002-04-18 Richard Henderson <rth@redhat.com> * ifcvt.c: Include except.h. (block_has_only_trap): Break out from find_cond_trap. (find_cond_trap): Use it. Always delete the trap block. (merge_if_block): Allow then block null. Be less simplistic about what insns can end a block. * Makefile.in (ifcvt.o): Depend on except.h. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=3927
