Fix Thumb-2 BL detection
2016-07-01 Thomas Preud'homme <thomas.preudhomme@arm.com>
bfd/
* elf32-arm.c (using_thumb2_bl): New function.
(arm_type_of_stub): Declare thumb2 variable together and change type
to bfd_boolean. Use using_thumb2_bl () to determine whether
THM_MAX_FWD_BRANCH_OFFSET or THM2_MAX_FWD_BRANCH_OFFSET should be
checked for BL range.
(elf32_arm_final_link_relocate): Use using_thumb2_bl () to determine
the bit size of BL offset.
ld/
* testsuite/ld-arm/arm-elf.exp (Thumb-2 BL): Assemble for ARMv7.
(Thumb-2 BL on ARMv6-M): New testcase.
* testsuite/ld-arm/thumb2-bl.d: Do not try to match testcase filename.
* testsuite/ld-arm/thumb2-bl.s: Do not select architecture.
