[PATCH] D75163: [analyzer][StreamChecker] Adding precall and refactoring.

[Kristóf Umann via Phabricator via cfe-commits]

Szelethus added inline comments.


================
Comment at: clang/lib/StaticAnalyzer/Checkers/StreamChecker.cpp:64-70
+/// Get the value of the stream argument out of the passed call event.
+/// The call should contain a function that is described by Desc.
+SVal getStreamArg(const FnDescription *Desc, const CallEvent &Call) {
+  assert(Desc && Desc->StreamArgNo != ArgNone &&
+         "Try to get a non-existing stream argument.");
+  return Call.getArgSVal(Desc->StreamArgNo);
+}
