New Revision: 260990
URL: http://llvm.org/viewvc/llvm-project?rev=260990&view=rev
Log:
clang-cl: Expose -isystem.
Like cl.exe, clang-cl allows adding system include directories via the
INCLUDE env var. Having a driver flag for this functionality is useful,
so add this too.
(In the future, we probably also want to have a flag alternative to
VCINSTALLDIR as used in MSVCToolChain::getVisualStudioBinaries(), and
a way to override the registry accesses in MSVCToolChain::getWindowsSDKDir()
-- maybe -ivcroot= and -iwinsdkroot=?).
