[PATCH] target/119010 - add znver{4,5}_insn_both to resolve missing reservations

[Richard Biener]

I still was seeing

;;        0--> b  0: i 101 {[sp-0x3c]=[sp-0x3c]+0x1;clobber flags;}:nothing

so the following adds a standard alu insn reservation mimicing that
from the znver.md description allowing both load and store.

Bootstrap and regtest running on x86_64-unknown-linux-gnu, OK?

        PR target/119010
        * config/i386/zn4zn5.md (znver4_insn_both, znver5_insn_both):
        New reservation for ALU ops with load and store.
