2014-12-23AVR: Only set link-relax elf flag when appropriate.Andrew Burgess2-1/+5
The AVR target uses a bit in the elf header flags to indicate if the object was assembled ready for linker relaxation. Previously this flag was always set, even when the object was not assembled ready for linker relaxation. This patch moves setting of the flag into the assembler, and sets it only when the assembler is preparing the file for linker relaxation. bfd/ChangeLog: * elf32-avr.c (bfd_elf_avr_final_write_processing): Don't set EF_AVR_LINKRELAX_PREPARED unconditionally. gas/ChangeLog: * config/tc-avr.c: Add include for elf/avr.h.
