ARM: Add support for value 3 of Tag_ABI_VFP_args attribute
*** bfd/ChangeLog *** 2014-12-25 Thomas Preud'homme <thomas.preudhomme@arm.com> * elf32-arm.c (elf32_arm_merge_eabi_attributes): Handle new Tag_ABI_VFP_args value and replace hardcoded values by enum values. (elf32_arm_post_process_headers): Set e_flags in ELF header as hard float only when Tag_ABI_VFP_args is 1, using new enum value AEABI_VFP_args_vfp to check that. *** binutils/ChangeLog *** 2014-12-25 Thomas Preud'homme <thomas.preudhomme@arm.com> * readelf.c (arm_attr_tag_ABI_VFP_args): Add "compatible". *** gdb/ChangeLog *** 2014-12-25 Thomas Preud'homme <thomas.preudhomme@arm.com> * arm-tdep.c (arm_gdbarch_init): Explicitely handle value 3 of Tag_ABI_VFP_args. Also replace hardcoded values by enum values in the switch handling the different values of Tag_ABI_VFP_args. *** gold/ChangeLog *** 2014-12-25 Thomas Preud'homme <thomas.preudhomme@arm.com> * arm.cc (Target_arm::do_adjust_elf_header): Set e_flags in ELF header as hard float only when Tag_ABI_VFP_args is 1, using new enum value AEABI_VFP_args_vfp to check that. (Target_arm::merge_object_attributes): Handle new Tag_ABI_VFP_args value and replace hardcoded values by enum values. *** include/elf/ChangeLog *** 2014-12-25 Thomas Preud'homme <thomas.preudhomme@arm.com> * arm.h: New AEABI_FP_number_model_* and AEABI_VFP_args_* enum values. *** ld/testsuite/ChangeLog *** 2014-12-25 Thomas Preud'homme <thomas.preudhomme@arm.com> * ld-arm/attr-merge-2a.s: Add Tag_ABI_VFP_args. * ld-arm/attr-merge-2b.s: Likewise. * ld-arm/attr-merge-2.attr: Likewise. * ld-arm/attr-merge-4a.s: Add Tag_ABI_FP_number_model and Tag_ABI_VFP_args. * ld-arm/attr-merge-4b.s: Likewise. * ld-arm/attr-merge-4.attr: Likewise. * ld-arm/attr-merge-6a.s: Likewise. * ld-arm/attr-merge-6b.s: Likewise. * ld-arm/attr-merge-6.attr: Add Tag_ABI_FP_number_model.
