--- Comment #8 from jwjagersma at gmail dot com --- Created attachment 51808 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51808&action=edit basic implementation Tentative patch. Produces working code but could use some (many) checks to diagnose incorrect usage, eg. AS-qualified struct fields, function parameters, non-type template parameters. Assigning an AS-qualified pointer to non-qualified is already diagnosed correctly, but the inverse is not. I don't know if mangling address-space-qualified member functions would be covered by ABI version 10, or if the version number needs to be bumped.
