There's no such register as f33 (nor any odd-numbered reg above f32).

+    // Double precision floating-point register
+    {{"d0"}, "f0"},   {{"d1"}, "f2"},   {{"d2"}, "f4"},   {{"d3"}, "f6"},
AFAICT, gcc doesn't actually accept "d" and "q" aliases in its inline asm, so probably no point in LLVM doing so either.
