I think so, or maybe even use reg_overlap_mentioned_p. It depends what
you're doing. For 4.4, it may be worth mo
I have a simple loop over the defs of an INSN, looking for the def of a
specific register X:
struct df_ref **defs;
for (defs = DF_INSN_DEFS (insn);
*defs && !rtx_equal_p (DF_REF_REG (*defs), x);
defs++)
;
It doesn't work because the modes don't match:
(gdb) call debug
