[PATCH] D98631: AMDGPU: Don't require registers for s_setpc_b64 operand

[Dmitry Preobrazhensky via Phabricator via llvm-commits]

dp added a comment.

> I don't see any restriction noted that this must be a register, so just allow any SSrc_b64 like normal.

Documentation is not clear here, however sp3 does not allow constants for src0 (as opposed to null).
