; The intent here is to test "X", which says that any operand whatsoever is allowed.
; Using this mechanism, we want to test toggling allocating GPR or SPR registers
; depending on whether the float registers are available. Thus, the mnemonic is
; totally irrelevant here, which is why we use FOO and also comment it out using "@"
; to avoid assembler errors.
; Note that this kind of IR can be generated by a function such as:
; void f1(float f) {asm volatile ("@FOO $0, $0" : : "X" (f));}
define arm_aapcs_vfpcc void @func(float %f) {
; NOVFP: FOO r0, r0
; VFP: FOO s0, s0
call void asm sideeffect "@FOO $0, $0", "X" (float %f) nounwind
