2014-11-03When relaxing, update size of symbols.Andrew Burgess2-8/+37
When performing linker relaxation, reduce the size of symbols that span the deleted bytes. This ensures that, for example, function symbols will have the correct size. bfd/ChangeLog: * elf32-avr.c (elf32_avr_relax_delete_bytes): During linker relaxation, reduce the size of symbols that span the deleted bytes. ld/ChangeLog: * testsuite/ld-avr/relax-02.d: Update to check size of symbols has changed. * testsuite/ld-avr/relax-03.d: Likewise.
