Use getters/setters to access ARM branch type
2016-05-10 Thomas Preud'homme <thomas.preudhomme@arm.com>
bfd/
* elf32-arm.c (elf32_arm_size_stubs): Use new macros
ARM_GET_SYM_BRANCH_TYPE and ARM_SET_SYM_BRANCH_TYPE to respectively get
and set branch type of a symbol.
(bfd_elf32_arm_process_before_allocation): Likewise.
(elf32_arm_relocate_section): Likewise and fix identation along the
way.
(allocate_dynrelocs_for_symbol): Likewise.
(elf32_arm_finish_dynamic_symbol): Likewise.
(elf32_arm_swap_symbol_in): Likewise.
(elf32_arm_swap_symbol_out): Likewise.
gas/
* config/tc-arm.c (arm_adjust_symtab): Use ARM_SET_SYM_BRANCH_TYPE to
set branch type of a symbol.
gdb/
* arm-tdep.c (arm_elf_make_msymbol_special): Use
ARM_GET_SYM_BRANCH_TYPE to get branch type of a symbol.
include/
* arm.h (enum arm_st_branch_type): Add new ST_BRANCH_ENUM_SIZE
enumerator.
(NUM_ENUM_ARM_ST_BRANCH_TYPE_BITS): New macro.
(ENUM_ARM_ST_BRANCH_TYPE_BITMASK): Likewise.
(ARM_SYM_BRANCH_TYPE): Replace by ...
(ARM_GET_SYM_BRANCH_TYPE): This and ...
(ARM_SET_SYM_BRANCH_TYPE): This in two versions depending on whether
BFD_ASSERT is defined or not.
ld/
* emultempl/armelf.em (gld${EMULATION_NAME}_finish): Use
ARM_GET_SYM_BRANCH_TYPE to get branch type of a symbol.
opcodes/
* arm-dis.c (get_sym_code_type): Use ARM_GET_SYM_BRANCH_TYPE to get
branch type of a symbol.
(print_insn): Likewise.
