For `NoStoreFuncVisitor`, this seems to be fine I suppose, though I'm not sure how things pan out for memory leaks.

For now, I'm leaning on the side of slightly too much than too little, but I need real world data on my hand to have a good feel for it. ================ Comment at: clang/lib/StaticAnalyzer/Core/BugReporterVisitors.cpp:399 +/// to get the correct parameter name. +static ArrayRef<ParmVarDecl *> getCallParameters(const CallEvent &Call) { + // Use runtime definition, if available. ---------------- NoQ wrote: > While we're at it, can you take a look if the recently introduced > `CallEvent::parameters()` is good enough for this? I suppose yeah, at least the lit tests all passed, though its worth mentioning that this function explicitly calls `CallEvent::parameters()`...
