Look in the source for that methods on x86 an
Hi Joel,
I have done a test, it seems that '-march=i386' does not provide
"__atomic_compare_exchange_n" libs. And '-march=i486' or '-march=pentium' can

I recall that one issue with *-rtems* targets is that
we support CPU models which are lower than typically

Hi Jonathan,
Thank you for your reply.
And about the error i encounter, do you have any advice? maybe it is caused by
my toolchain not install rightly?
In the standard pc686 architecture(not cross compile on RTEMS) will it
