From 066c260ad09dde95f43e503f7242b011d17a10f6 Mon Sep 17 00:00:00 2001 From: Ken Matsui Date: Fri, 14 Jul 2023 19:55:35 -0700 Subject: [PATCH] libstdc++: Use __bool_constant entirely This patch uses __bool_constant entirely instead of integral_constant in the type_traits header, specifically for true_type, false_type, and bool_constant. libstdc++-v3/ChangeLog: * include/std/type_traits (true_type): Use __bool_constant instead. (false_type): Likewise. (bool_constant): Likewise.
