Hi.
When I try to use an atomic builtin, it gives an error like:

libgccjit.so: error: /tmp/libgccjit-1VoggR/fake.so: undefined symbol: __atomic_store_n

I tried setting the arch with:

gcc_jit_context_add_command_line_option(ctxt, "-march=x86-64");


but it didn't change anything.

From inspecting the source code of gcc, it seems it does not support that yet because it does not call resolve_overloaded_builtin (I might be wrong, I don't have much knowledge of the gcc codebase).

So, is there a way to do that currently or is it a bug?

Thanks.
