clang::ast_matchers::AST_MATCHER_P	(	Expr	,

		InnerMatcher
	)

Matches expressions that match InnerMatcher that are possibly wrapped in an elidable constructor and other corresponding bookkeeping nodes.

In C++17, elidable copy constructors are no longer being generated in the AST as it is not permitted by the standard. They are, however, part of the AST in C++14 and earlier. So, a matcher must abstract over these differences to work in all language modes. This matcher skips elidable constructor-call AST nodes, ExprWithCleanups nodes wrapping elidable constructor-calls and various implicit nodes inside the constructor calls, all of which will not appear in the C++17 AST.

Given

struct H {};
H G();
void f() {
  H D = G();
}

varDecl(hasInitializer(ignoringElidableConstructorCall(callExpr()))) matches H D = G() in C++11 through C++17 (and beyond).
