New Revision: 68665
URL: http://llvm.org/viewvc/llvm-project?rev=68665&view=rev
Log:
Make -include, -imacros paths absolute in Frontend.
- Otherwise paths will be resolved relative to the main input file,
which is incorrect.
- I don't know how to make a reasonable test case for this with our
testing infrastructure.
