Make the + symtab point to the macro information, and clear the + `pending_macros' pointer which held it while we were reading the + debug info. + (really_free_pendings): Free any pending macro table. + * objfiles.h (struct objfile): New member: `macro_cache'. + * objfiles.c (allocate_objfile): Set allocate and free functions + for the macro cache's objstack. + (free_objfile): Empty the macro cache's obstack. + * symfile.c (reread_symbols): Empty the macro cache's obstack, and + set new allocate and free functions for it. + * solib-sunos.c (allocate_rt_common_objfile): Set allocate and + free functions for the macro cache's objstack.
