PR target/96558: Only call ix86_expand_clear with GENERAL_REGS.
The following patch tightens the predicates of the peephole2 from my recent
"Integer min/max improvements patch" to only hoist clearing a register when
that register is a general register. Calling ix86_expand_clear with regs
other than GENERAL_REGS is not supported.
