[PATCH] D130560: [RISCV] Handle register spill in branch relaxation

[Celeste Liu via Phabricator via llvm-commits]

CoelacanthusHex added a comment.

There seems to be a problem here: if we perform only some operations on registers without sd after a jump (which can easily happen if only a few short instructions are executed between jumps), we then jump to another place. If we still restore immediately in this case, we are actually wasting resources.
