re PR target/93174 (ICE building glibc __sha512_process_block for i686)
PR target/93174
* config/i386/i386.md (addcarry<mode>_0): Use nonimmediate_operand
predicate for output operand instead of register_operand.
(addcarry<mode>, addcarry<mode>_1): Likewise. Add alternative with
memory destination and non-memory operands[2].
* gcc.c-torture/compile/pr93174.c: New test.
