Subject: Add c-index-test -test-load-source, which loads the translation unit from a source... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ada487d498d82277bbc60312fc6f6479f0afda76;p=clang

Add c-index-test -test-load-source, which loads the translation unit from a source file (and other command line arguments).

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90187 91177308-0d34-0410-b5e6-96231b3b80d8
