In a later patch we're going to change the minimal symbol address calculation to apply section offsets at the point of use. To make it simpler to catch potential problem spots, this patch changes the representation of minimal symbols and introduces new minimal-symbol-specific variants of the various accessors. This is necessary because it would be excessively ambitious to try to convert all the symbol types at once. The core of this change is just renaming a field in minimal_symbol; the rest is just a fairly mechanical rewording. 2014-02-26 Tom Tromey <tromey@redhat.com> * symtab.h (struct minimal_symbol) <mginfo>: Rename from ginfo.
