llvm-capstone/clang/test/Analysis/temp-obj-dtors-cfg-output.cpp
Jordan Rose 1e0e4001c8 [analyzer] For now, don't inline C++ standard library functions. 
This is a (heavy-handed) solution to PR13724 -- until we know we can do
a good job inlining the STL, it's best to be consistent and not generate
more false positives than we did before. We can selectively whitelist
certain parts of the 'std' namespace that are known to be safe.

This is controlled by analyzer config option 'c++-stdlib-inlining', which
can be set to "true" or "false".

This commit also adds control for whether or not to inline any templated
functions (member or non-member), under the config option
'c++-template-inlining'. This option is currently on by default.
