Piotr,
Hello. First, a note: you should be sending libstdc++ mail to the
[EMAIL PROTECTED] list.
I haven't verified your claim, but if it is true, I would suggest the
following actions on your part to solve it:
1) enter a sparc backend bug in gcc bugzilla about not defining __sparcv9 in 32
bit
Hello,
why there is no cas-based version of __exchange_and_add for 32-bit
mode Sparcs in libstdc++, namely in config/cpu/sparc/atomicity.h ?
There is spinlock-based generic code for all Sparcs, but V9 does support
32-bit cas, which can be used instead of a spinlock. This spinlock
_Atomicity_lock<
