[cfe-dev] Finding all instances of calls to a specific function using ASTMatcher

[Nikola Smiljanic]

Use clang-query to try things out, you'll need to generate compilation
database to use it but that shouldn't be too hard. It sure beats having to
recompile your code to test it.

The matcher you're after is probably
callExpr(callee(functionDecl(hasName("malloc"))))

now, I can find all the function calls using ASTMatcher using following
code:

know how do that using classic "RecursiveASTVisitor" class, but how can I
do this using ASTMatcher?
