@antoyo i need some clarity on impl. the tile intrinsics. currently, I see a few possible approaches:

1. Usingget_target_builtin_function, but this fails with "Cannot find target builtin" errors since these don't have GCC builtin equivalents.

2. Creating custom functions with inline assembly, something like:

"llvm.x86.ldtilecfg" =>{let name ="__rustc_tile_ldtilecfg";let func = cx.context.new_function(None,FunctionType::Internal,        cx.type_void(),&[/* params */],        name,false,);}

Yeah,get_target_builtin_function won't work.

Perhaps your solution#2 would be the simplest (if that works). You could add the attribute AlwaysInline to make sure it's efficient.

Otherwise, I see another solution involving changing thetype Function to anenum that would either take aFunction or inline asm, but that might be a lot of work, so I would go with#2 if that works.
