X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f12d1e8a660c34ce3098da788ac01d067d6ccbab;p=binutils-gdb.git

ARM: Add support for value 3 of Tag_ABI_VFP_args attribute

Missing from 5c294fee

elfcpp/
	* arm.h: Add enums for Tag_ABI_FP_number_model and Tag_ABI_VFP_args.
gold/
	* arm.cc (Target_arm::do_adjust_elf_header): Provide namespace on
	new enums.
	(Target_arm::merge_object_attributes, ): Likewise.
