; 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));}
