New Revision: 347833
URL: http://llvm.org/viewvc/llvm-project?rev=347833&view=rev
Log:
Add Hurd target to Clang driver (2/2)
This adds Hurd toolchain support to Clang's driver in addition
to handling translating the triple from Hurd-compatible form to
the actual triple registered in LLVM.
(Phabricator was stripping the empty files from the patch so I
manually created them)
