// WMMA builtins.
// Postfix w32 indicates the builtin requires wavefront size of 32.
// Postfix w64 indicates the builtin requires wavefront size of 64.
//
// Some of these are very similar to their GFX11 counterparts, but they don't
// require replication of the A,B matrices, so they use fewer vector elements.
// Therefore, we add an "_gfx12" suffix to distinguish them from the existing
// builtins.
