Reduce parameter list in bfd_elf32_arm_target_relocs

2016-08-26  Thomas Preud'homme  <thomas.preudhomme@arm.com>

bfd/
	* bfd-in.h (struct elf32_arm_params): Define.
	(bfd_elf32_arm_set_target_relocs): Rename into ...
	(bfd_elf32_arm_set_target_params): This.  Use a struct
	elf32_arm_params to pass all parameters but the bfd and bfd_link_info.
	* bfd-in2.h: Regenerate.
	* elf32-arm.c (bfd_elf32_arm_set_target_relocs): Rename into ...
	(bfd_elf32_arm_set_target_params): This.  Pass all values via a struct
	elf32_arm_params rather than as individual parameters.

ld/
	* emultempl/armelf.em (params): New static variable.
	(thumb_entry_symbol, byteswap_code, target1_is_rel, target2_type,
	fix_v4bx, use_blx, vfp11_denorm_fix, stm32l4xx_fix, fix_cortex_a8,
	no_enum_size_warning, no_wchar_size_warning, pic_veneer,
	merge_exidx_entries, fix_arm1176, cmse_implib): move as part of the
	above new structure.
	(arm_elf_before_allocation): Access static variable from the params
	structure.
	(gld${EMULATION_NAME}_finish): Likewise.
	(arm_elf_create_output_section_statements): Likewise and pass the
	address of that structure to bfd_elf32_arm_set_target_relocs instead
	of the static variables.
	(PARSE_AND_LIST_ARGS_CASES): Access static variable from the params
	structure.
