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.
