This register is only supported on the *powerpc*spe targets. It is only recognized by LLVM. gcc does not accept this as a clobber, nor does it support these targets. This is a volatile register, thus it is included with clobber_abi.
The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
