What is the data type for _tile_dpfp16ps, where is the data type defined? I get an gcc 13 error for the type of function _tile_dpfp16ps?

That particular call (_tile_dpfp16ps) is implemented in GCC as a macro, but elsewhere I found this definition for __tile.

Bochs 2.8 emulates AMX and many of the other of the instruction sets still missing in SIMDe.
