Subject: [analyzer] SATestBuild.py: Use driver for analyzing single-file tests.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=df36e33d6e41fc2bbf8b02661efa4e3ebb06a9bd;p=clang

[analyzer] SATestBuild.py: Use driver for analyzing single-file tests.

Don't bother coming up with a -cc1 run-line ourselves.

This, in particular, gets rid of a macOS-specific code path.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@362009 91177308-0d34-0410-b5e6-96231b3b80d8
