// RUN: clang-check -analyze "%s" -- -c 2>&1 | FileCheck %s
[Tooling] Allow -flto flags and filter out -Wa, flags This change fixes the problem in https://bugs.llvm.org/show_bug.cgi?id=38332 by allowing driver::Action::BackendJobClass to run with the analyzer. Otherwise, such jobs will look up the non-existing compilation database and then run without flags. Also filter out the -Wa,* flags that could be passed to and ignored by the clang compiler. Clang-tidy gives warnings about unused -Wa,* flags. Differential Revision: http://reviews.llvm.org/D51002 llvm-svn: 340421
