Subject: libstdc++: Add relational operators to __gnu_test::PointerBase
X-Git-Tag: basepoints/gcc-15~8890
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d2fa90a41567670d2dbd4918d19d21d9bec4a8f;p=thirdparty%2Fgcc.git

libstdc++: Add relational operators to __gnu_test::PointerBase

The Cpp17Allocator requirements say that an allocator's pointer and
const_pointer types must meet the Cpp17RandomAccessIterator
requirements. That means our PointerBase helper for defining fancy
pointer types should support the full set of relational operators.

libstdc++-v3/ChangeLog:

	* testsuite/util/testsuite_allocator.h (PointerBase): Add
	relational operators.
