Bug ID: 96079 Summary: Unresolved atomic builtins Product: gcc Version: 10.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: jit Assignee: dmalcolm at gcc dot gnu.org Reporter: bouanto at zoho dot com Target Milestone: --- Created attachment 48836 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48836&action=edit Reproducer 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.
