re PR rtl-optimization/79901 (ICE in prepare_cmp_insn, at optabs.c:3904)
PR rtl-optimization/79901
* config/i386/sse.md (*avx512bw_<code><mode>3<mask_name>): Renamed to
...
(*avx512f_<code><mode>3<mask_name>): ... this.
(<code><mode>3 with maxmin code iterator): Use VI8_AVX2_AVX512F
iterator instead of VI8_AVX2_AVX512BW.
* gcc.target/i386/pr79901.c: New test.
