I am agree with Jeff and Richard. There is one more reason to avoid using
hard registers. Usage of hard registers tends to create more spill failures
It is not like you have a choice here. The register for those insns is fixed.
Sooner or later you have to allocate xmm0 for them.
I will open a bug where gcc generates inefficient code whenThat's fine.
hard register isn't used early.
