Subject: [PATCH v21 20/23] c++: Implement __is_invocable built-in trait
Date: Fri,  3 May 2024 13:52:56 -0700	[thread overview]
Message-ID: <20240503205259.360779-21-kmatsui@gcc.gnu.org> (raw)
In-Reply-To: <20240503032531.1247607-24-kmatsui@gcc.gnu.org>

Fixed datum reference problem.  Ok for trunk?

-- >8 --

This patch implements built-in trait for std::is_invocable.

gcc/cp/ChangeLog:

	* cp-trait.def: Define __is_invocable.
	* constraint.cc (diagnose_trait_expr): Handle CPTK_IS_INVOCABLE.
	* semantics.cc (trait_expr_value): Likewise.
	(finish_trait_expr): Likewise.
	* cp-tree.h (build_invoke): New function.
	* method.cc (build_invoke): New function.

gcc/testsuite/ChangeLog:

	* g++.dg/ext/has-builtin-1.C: Test existence of __is_invocable.
	* g++.dg/ext/is_invocable1.C: New test.
	* g++.dg/ext/is_invocable2.C: New test.
	* g++.dg/ext/is_invocable3.C: New test.
	* g++.dg/ext/is_invocable4.C: New test.
