| ; 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));} | |
