------- Comment #60 from steven at gcc dot gnu dot org 2006-01-20 00:06 -------
I've tested it on x86_64-unknown-linux-gnu and mips-elf (simulator, C only).
Richi, I would have commited the patch for this myself as obvious, with a
comment explaining why we have to call ir_type there and a promise to follow up
with a patch for rtl_verify_flow_info to explicitly check for every edge that
the EDGE_{TRUE,FALSE}_VALUE flags are not set.
I suggest you now commit the patch to mainline at least and maybe wait for Mark
to give a verdict for GCC 4.1. I'll craft the patch to do the extra checking
some time next week.
