Commit Message

Ken Matsui Oct. 13, 2023, 10:37 p.m. UTC 
  This patch implements built-in trait for std::is_pointer.

gcc/cp/ChangeLog:

	* cp-trait.def: Define __is_pointer.
	* cp-trait.gperf: Reflect cp-trait.def change.
	* cp-trait.h: Likewise.
	* constraint.cc (diagnose_trait_expr): Handle CPTK_IS_POINTER.
	* semantics.cc (trait_expr_value): Likewise.
	(finish_trait_expr): Likewise.

gcc/testsuite/ChangeLog:

	* g++.dg/ext/has-builtin-1.C: Test existence of __is_pointer.
	* g++.dg/ext/is_pointer.C: New test.
