Subject: [analyzer] scan-build: Teach ccc-analyzer about -Xclang.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1315efcc022d15c95c9d432dce46488b7dfa5ceb;p=clang

[analyzer] scan-build: Teach ccc-analyzer about -Xclang.

Update ccc-analyzer to forward both -Xclang and its following argument to the
the compiler driver. Previously we were dropping -Xclang and forwarding the
argument on its own if it matched other forwarding criteria. This caused the
argument to be interpreted as a driver rather than a frontend option.
