...existing SSE/SSE2 compiler builtins, on both x86-32 and x86-64, and then *delete the MMX implementation of these intrinsics*. We would thus stop supporting the use of these intrinsics, without SSE2 also enabled. I've created a preliminary patch for these header changes, https://reviews.llvm.org/D86855. Sometime later, we should then remove the MMX intrinsics in LLVM IR. (Only the intrinsics -- the machine-instruction and register definitions for MMX should be kept indefinitely for use by assembly code.) That raises the question of bitcode compat. Maybe we do something to prevent new use of the...
