Commit r12-2534 was incomplete and (by inspection derived
from an MMIX build) failing for targets without an insn for
compare_and_swap for pointer-size objects, IOW for targets
for which "ATOMIC_POINTER_LOCK_FREE != 2" is true:
x/gcc/libstdc++-v3/src/c++17/memory_resource.cc: In member function
'std::pmr::memory_resource*
std::pmr::{anonymous}::atomic_mem_res::exchange(std::pmr::memory_resource*)':
x/gcc/libstdc++-v3/src/c++17/memory_resource.cc:140:21: error:
'exchange' is not a member of 'std'
140 | return std::exchange(val, r);
| ^~~~~~~~
make[5]: *** [Makefile:577: memory_resource.lo] Error 1
make[5]: Leaving directory
'/home/hp/tmp/newmmix-r12-2579-p3/gccobj/mmix/libstdc++-v3/src/c++17'
This fix was derived from edits elsewhere in that patch.
Tested mmix-knuth-mmixware, restoring build (together with
target-reviving patches as MMIX is currently and at that commit
broken for target-specific reasons).
libstdc++-v3/:
* src/c++17/memory_resource.cc: Use __exchange instead
of std::exchange.
