[cfe-dev] Best way to know if a method declaration is defined in the source

[Mustakimur Rahman Khandaker via cfe-dev]

I am not sure if the following procedure is correct for this purpose, I will like if someone ensure if it is correct to do so.

const CXXMethodDecl *MD = cast<CXXMethodDecl>(CGF.CurGD.getDecl());
if (isa<CXXConstructorDecl>(MD)) {
auto *classDecl = MD->getParent();
if (!classDecl->isCXX11StandardLayout()) {
// constructor of user-defined class
}
}

Like I don't want to have ios_base constructor but I want Employee constructor that is either implicitly or explicitly defined because the class is user-defined.

In the codegen, I have encountered number of methods thats are not part of my test source code, so if I try to modify them in codegen, they have broken down. Is there any flag or other way using sourcelocation to discard those method declaration from modification.
