------- Comment #4 from steven at gcc dot gnu dot org 2007-08-14 21:34 -------
r127273 is this patch: http://gcc.gnu.org/ml/gcc-cvs/2007-08/msg00165.html
My initial reaction was, "What happens to the REG_RETVAL note, if the insn with
the REG_LIBCALL note?" I don't know what happens with the REG_LIBCALL note,
but if it disappears with the insn that's being deleted, then you should also
remove the REG_RETVAL note, or you're creating something that will look like
nested libcalls (which gcse.c handles, but they're actually not allowed).
So, can you check what happens with the REG_RETVAL note, please?
