I think the easiest way to handle this would be for the driver to disable
-fwhole-program when the IL is being generated. Otherwise, all the symbols are

I believe we should be set already. During LTO read, we execute
ipa_passes, which runs all_small_ipa_passes. So,
pass_ipa_function_and_variable_visibility
13 matches
