[PATCH] D16135: Macro Debug Info support in Clang

[Amjad Aboud via Phabricator via cfe-commits]

aaboud updated this revision to Diff 87796.
aaboud added a comment.

Added flag to control macro debug info generation:

1. -fdebug-macro (-fno-debug-macro) for Clang driver
2. -debug-info-macro for Clang compiler (-cc1)

Also, made sure FE will discard this flag when debug info is not required, i.e. with -g0.
Should we discard the macro debug info when "-gline-tables-only" is used? or it is up to the user not to use "-fdebug-macro" in this case?

I also extended the test to check all combinations of using -debug-info-macro flag with -debug-info-kind flag.
