should not be used together, we choose not\nto use the same intrin name for ACE and legacy AMX, while the builtins\ncould be shared.\n\nFor AMX-TILE related insts, we add \"_ace_\" in the middle of the intrin\nname to explicitly mention the intrin is used by ACE.\n\nFor tilerelease, we keep it simple for now to use inline assembly since\nno tmm register number need to be mentioned for the intrin and using\npattern does not help compiler knowing the dependency.\n\ngcc/ChangeLog:\n\n\t* config.gcc: Include acev1intrin.h.\n\t* config/i386/i386-builtin-types.def: Add new function type.\n\t*
