change minsyms not to be relocated at read-time
This removes the runtime offsets from minsyms. Instead, these offsets will now be applied whenever the minsym's address is computed. This patch redefines MSYMBOL_VALUE_ADDRESS to actually use the offsets from the given objfile. Then, it updates all the symbol readers, changing them so that they do not add in the section offset when creating the symbol. This change also lets us remove relocation of minsyms from objfile_relocate1 and also msymbols_sort. 2014-02-26 Tom Tromey <tromey@redhat.com> * minsyms.c (msymbols_sort): Remove. * minsyms.h (msymbols_sort): Remove. * objfiles.c (objfile_relocate1): Don't relocate minsyms. * symtab.h (MSYMBOL_VALUE_ADDRESS): Use objfile offsets. * elfread.c (elf_symtab_read): Don't add section offsets. * xcoffread.c (record_minimal_symbol): Don't add section offset to minimal symbol address. * somread.c (text_offset, data_offset): Remove.
