bfd:
* elf32-arm.c (elf32_arm_print_private_bfd_data): Recognise and display the new ARM hard-float/soft-float ABI flags for EABI_VER5 (elf32_arm_post_process_headers): Add the hard-float/soft-float ABI flag as appropriate for ET_DYN/ET_EXEC in EABI_VER5. binutils: * readelf.c (decode_ARM_machine_flags): Recognise and display the new ARM hard-float/soft-float ABI flags for EABI_VER5. Split out the code for EABI_VER4 and EABI_VER5 to allow this. elfcpp: * arm.h: New enum for EABI soft- and hard-float flags. gold: * gold.cc (Target_arm::do_adjust_elf_header): Add the hard-float/soft-float ABI flag as appropriate for ET_DYN/ET_EXEC in EABI_VER5. include: * elf/arm.h (EF_ARM_ABI_FLOAT_SOFT): New define. (EF_ARM_ABI_FLOAT_HARD): Likewise. ld/testsuite: * ld-arm/eabi-hard-float.s: New test source. * ld-arm/eabi-soft-float.s: New test source. * ld-arm/eabi-hard-float.d: New test. * ld-arm/eabi-soft-float.d: New test. * ld-arm/eabi-soft-float-ABI4.d: New test. * ld-arm/eabi-soft-float-r.d: New test. * ld-arm/arm-elf.xp: Use the new tests. binutils: PR binutils/14779 * configure.in: Add checks for wchar.h and mbstate_t. * config.in: Regenerate. * configure: Regenerate. * readelf.c: Conditionally include wchar.h. (print_symbol): Conditionally use mbstate_t.
