target/119010 - fixup zn4zn5 reservation for move from const_vector
movv8si_internal uses sselog1 and V4SFmode for an instruction like
(insn 363 2437 371 97 (set (reg:V8SI 46 xmm10 [1125])
(const_vector:V8SI [
(const_int 0 [0]) repeated x8
])) "ComputeNonbondedUtil.C":185:21 2402 {movv8si_internal}
this wasn't catched by the existing znver4_sse_log1 reservation,
I think the znver automaton catches this with the generic
(define_insn_reservation "znver1_sse_log1" 1
(and (eq_attr "cpu" "znver1,znver2,znver3")
(and (eq_attr "type" "sselog1")
(eq_attr "memory" "none")))
"znver1-direct,znver1-fp1|znver1-fp2")
which does not look at the mode at all. The zn4zn5 automaton lacks
this and instead has separated store and load-store reservations
in odd ways. The following renames the store one and introduces
a none variant.
PR target/119010
* config/i386/zn4zn5.md (znver4_sse_log1): Rename to
znver4_sse_log1_store.
(znver5_sse_log1): Rename to znver5_sse_log1_store.
(znver4_sse_log1): New memory-less variant.
