Yep. I remember this issue well.
Also, please note that just having powerpc processor instructions
seems to also be insufficient, at least for some powerpc chips. See
libstdc++/7383. I'd appreciate it if a powerpc maintainer could figure
out how to work ppc405 work-arounds into the libstdc++ atomicity.h file.
The work is mostly done and in the PR. Can I assign it to somebody,
and if so, who?
thanks!
