PR preprocessor/34692
* macro.c (collect_args): Add pragma_buff argument. Push
CPP_PRAGMA ... CPP_PRAGMA_EOL tokens to *pragma_buff, rather
than into arguments. Reset prevent_expansion and parsing_args
state at CPP_PRAGMA_EOL/CPP_EOF.
(funlike_invocation_p): Add pragma_buff argument, pass it through
to collect_args.
(enter_macro_context): Add result argument. Adjust
funlike_invocation_p caller. Emit all deferred pragma tokens
gathered during collect_args before the expansion, add a padding
token. Return 2 instead of 1 if any pragma tokens were prepended.
(cpp_get_token): If enter_macro_context returns 2, don't return
a padding token, instead cycle to grab CPP_PRAGMA token.
* directives.c (_cpp_handle_directive): If was_parsing_args
in deferred pragma, leave parsing_args and prevent_expansion as is.
* gcc.dg/cpp/pr34692.c: New test.
* gcc.dg/gomp/pr34692.c: New test.
