--- Comment #8 from Gaius Mulley <gaius at gcc dot gnu.org> --- Created attachment 59072 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59072&action=edit Proposed fix for location_t and tree -Wodr warnings This patch fixes the -Wodr warning for m2tree_Tree vs tree and m2linemap_location_t vs location_t. The m2 front end uses tree and location_t and the bootstrap tool has been modified to include gcc headers for these data types. After this patch has been applied, the lto -Wodr build finds 33 warnings related to char *, void * and const char *. I'm hopeful that these are the last remaining set of -Wodr violations and suspect they can be solved by introducing a module CFamily which will export CharStar, ConstCharStar and the bootstrap tool will cast between these and the type ADDRESS as required.
