[PATCH] D133376: Allow epilogue_begin to be emitted when generating DWARF

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

> As one might expect, the section that grew is .debug_line. I see an increases of about 2%. However, the overall size of just the debug info increases by considerably less, about 0.3%. The increase of the overall file size is even less, at about 0,2%.

Under what build configuration/example target? These numbers can vary pretty widely depending on compression, split dwarf, optimized/unoptimized, etc. Might be good to have a few scenarios covered, at least with clang or something similarly large-ish from the LLVM project.

> Interestingly, I saw small reductions in the sizes of the .debug_line_str and .debug_str sections.

that seems really suspicious - is there any reason why this change would reduce those?
