Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,}.
Ok for trunk?
This patch supports sminmax for partial vectorized V2BF/V4BF.
gcc/ChangeLog:
* config/i386/mmx.md (<code><mode>3): New define_expand for
V2BF/V4BFsmaxmin
gcc/testsuite/ChangeLog:
* gcc.target/i386/avx10_2-partial-bf-vector-smaxmin-1.c: New test.
