Hi,
I am using GCC 4.1.2, and so no __atomic*().
I am looking at http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Atomic-Builtins.html
I see __sync_fetch_and_*(), but I don't see __sync_fetch(). Is it because the built-in routines support integral scalar or pointer type that is up to 8 bytes in length, and so the read is automatically atomic anyway?
Thanks in advance.
Cheers,
Hei
