Subject: [PATCH] define builtins for "shared" avxneconvert-avx512bf16vl
builtins.
This should fix incorrect error when call those builtin with
-mavxneconvert and w/o -mavx512bf16 -mavx512vl.
gcc/ChangeLog:
* config/i386/i386-builtins.cc (def_builtin): Handle "shared"
avx512bf16vl-avxneconvert builtins.
gcc/testsuite/ChangeLog:
* gcc.target/i386/avxneconvert-1.c: New test.
