This is enabled only under -ffast-math.
So, instead of emitting:
4007b0: 50 push %rax
4007b1: e8 8a fd ff ff callq 400540 <atanf@plt>
4007b6: 58 pop %rax
4007b7: e9 94 fd ff ff jmpq 400550 <tanf@plt>
4007bc: 0f 1f 40 00 nopl 0x0(%rax)
for:
float mytan(float x) {
return tanf(atanf(x));
}
we emit a single retq.
