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

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfo.cpp:999
+    int FrameIndex = RVMFI->getBranchRelaxationScratchFrameIndex();
+    assert(FrameIndex != -1 && "underestimated function size");
+
----------------
You probably want to report_fatal_error if you don't have a frame index, so you get an error in release builds if the heuristic breaks somehow.
