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

[ChenZheng via Phabricator via llvm-commits]

shchenz added a comment.

The buildbot failure is caused by instructions are inserted into prologue after empty prologue is checked. So if instructions are inserted to a empty prologue, because we save the first loc for empty prologue, then the inserted instructions will not appear in the debug line section because they are all after the first loc. So with such dwarf debug line, llvm-symbolizer can not find the location for these prologue instructions.
