New Revision: 257468
URL: http://llvm.org/viewvc/llvm-project?rev=257468&view=rev
Log:
Revert r253898 and r253899, this breaks mingw compilation on openSUSE.
Will re-apply after llvm 3.8 is branched.
Original commit message:
Driver: fallback to the location of clang if no sysroot,
hard coding /usr makes little sense for mingw-w64.
If we have portable toolchains having /usr breaks that.
If the clang we use is in /usr/bin or /usr/sbin etc this will
still detect as though it was hard coded to /usr
This makes the most sense going forward for mingw-w64 toolchains
on both linux and mac
