Hi
This change adds BFmode support to the ix86_preferred_simd_mode function
enhancing SIMD vectorization for BF16 operations. The update ensures
optimized usage of SIMD capabilities improving performance and aligning
vector sizes with processor capabilities.
Bootstrapped and tested on x86-64-pc-linux-gnu.
Ok for trunk?
gcc/ChangeLog:
* config/i386/i386.cc (ix86_preferred_simd_mode): Add BFmode Support.
