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

[Piggy via Phabricator via llvm-commits]

piggynl added a comment.

- More conservative estimate for branches in `EstimateFunctionSizeInBytes`.

- Remove the size of constants and jump tables in `EstimateFunctionSizeInBytes`.

- Add the new stack frame index to `RS` in `RISCVFrameLowering::processFunctionBeforeFrameFinalized`.

- Use `report_fatal_error` in `RISCVInstrInfo::insertIndirectBranch` if function size is underestimated.
