I have a patch to upgrade most genrecog warnings into errors. This patch
fixes one for m32c about stzx_16 and stzx_24_<mode> allowing constant integers
as destinations (as in, that's what the predicates would accept).
Tested by building m32c-elf with the warnings turned to errors, and by
comparing the before and after assembly output at -O2 for gcc.c-torture,
gcc.dg and g++.dg. OK to install?
Thanks,
Richard
gcc/
* config/m32c/cond.md (stzx_16): Use register_operand for operand 0.
(stzx_24_<mode>): Likewise mra_operand.
