– 11) Feature detection
Member detection exists now; that’s how we handle per-member differences such as whether quad (128-bit) arithmetic is present. The specializer replaces non-existent genAsm operations with synthesized calls on library functions, often inlined. There is not currently any way to do feature (as opposed to member) detection in source that gets passed through; you’d use pre-processor facilities to build targeted genAsm, or select the desired genAsm in the prelinker. This may change as we get further into the OS work.
