Subject: [committed] libstdc++: Simplify typedefs by using __UINTPTR_TYPE__
Date: Tue, 14 Dec 2021 21:47:47 +0000 [thread overview]
Message-ID: <20211214214747.2133070-1-jwakely@redhat.com> (raw)
Tested powerpc64le-linux, pushed to trunk.

* include/ext/pointer.h (_Relative_pointer_impl::_UIntPtrType):
Rename to uintptr_t and define as __UINTPTR_TYPE__.
