[PATCH] D136309: [clang][Toolchains][Gnu] pass -g through to assembler

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

Many -g options unfortunately enable/disable debug info emission: -g, -g[0123], -ggdb[0123], etc. The full rules are very complex. I think it makes sense to support a subset which is mostly likely used, i.e. -g, -g[0123]. So you may check `OPT_g_Group` and possibly reuse `DebugLevelToInfoKind` (if you want to support -ggdb0) or just hard code OPT_g0 if you just want to support -g0.
