Yes, on POWER. From our ABI: On processors with the VMX feature. v0-v1 Volatile scratch registers v2-v13 Volatile vector parameters registers v14-v19 Volatile scratch registers v20-v31 Non-volatile registers I'll note that the new VSX register state we recently added with power7 were made volatile, but then we already had these non-volatile altivec regs to use.
