[cfe-dev] Clang 3.3: --analyze produces object file full of XML (plist)

>From what I know the analyzer cannot be run at the same time as compiling the
program; you have to do a separate run. This page describes how it's done:
<http://clang-analyzer.llvm.org/scan-build.html>.

Given that the static analyzer is much slower than compilation I don't think
it's wise to run it every time. But you could set it up so it runs e.g. as part
of your unit tests.


HTH,
