[cfe-dev] Atomic operations/builtins and Windows

[Ruben Van Boxem]

Hi,

What is the status/usability of Clang's builtin atomic functions, especially
on Windows? Are the builtins related to the availability of pthreads or not?

It seems libc++ uses these builtins, but for *-*-mingw*, they're undeclared
:(

Can Clang "tap into" the GCC implementations?

Thanks,

Ruben
