[PATCH] D71978: [RISCV] Fix evalutePCRelLo for symbols at the end of a fragment

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Instead of returning a symbol difference from evaluatePCRelLo and folding it MCAssembler, can just fold the symbol difference to a constant in evaluatePCRelLo itself? MCExpr::evaluateAsRelocatableImpl does something like that in EvaluateSymbolicAdd.

If we can't do that for some reason, FKF_Target seems reasonable.
