[PATCH] D147506: [DebugLine] save one debug line entry for empty prologue

[ChenZheng via Phabricator via llvm-commits]

shchenz added a comment.

Added a simple assert in `MCObjectStreamer::emitDwarfAdvanceLineAddr()` for the absolute address diffs, and run a unittest check in llvm. All the failures are for assembly file (hardcode two `.loc` without any "real" instructions between). The `ll` input can not produce 0 address diff.
