[cfe-dev] controlling the value of DW_AT_comp_dir

[Nick Lewycky]

This is a follow-up to the thread that started here:

http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20110725/125101.html

Would anyone object to a flag "-fdwarf-compilation-dir=..." clang flag that
would clobber the DW_AT_comp_dir setting?

This is a gcc compatibility issue for us as we're relying on our ability to
control this part of the debug output by setting $PWD. A flag would also
work for me.
