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.
