question regarding atomicity.h on powerpc

Tue Jul 8 12:15:00 GMT 2003

Hi,

I just checked libstdc++-v3/config/cpu/powerpclibstdc++-v3/config/cpu/powerpc/atomicity.h
in GCC head CVS (upcoming 3.4).

The asm constructs are probably missing an "isync" after the last "bne".

And both are probably missing an "lwsync" or "eieio" before the loop to
sync the out of order data stores.

Can someone with more indepth gcc/powerpc knowledge please check it?

Ciao, Marcus
