Accepting an non-exist(future defined) register in the asm clobber list should
not cause any issue in the compiler side, I think. The register allocator can
not allocate these future defined registers anyhow.
The more serious issue is that clang accepts vsx instructions in asm block even
for targets that does not have VSX, see https://godbolt.org/z/rYnMbPPTE (gcc
has same behavior.)
