Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
bfd/

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.
