        PR target/85445
        * config/nvptx/nvptx.c (nvptx_emit_forking, nvptx_emit_joining):
        Emit insns for calls too.
        (nvptx_find_par): Always look for worker-level predecessor insn.
        (nvptx_propagate): Add is_call parm, return bool.  Copy frame for
        calls.
        (nvptx_vpropagate, nvptx_wpropagate): Adjust.
        (nvptx_process_pars): Propagate frames for calls.

        * testsuite/libgomp.oacc-c++/ref-1.C: New.
