* arm.cc (Arm_relocate_functions::abs8, Arm_relocate_functions::abs16): Use correct check for overflow specified in the ARM ELF specs. (Arm_relocate_functions): thumb_branch_common. Handle bit 1 of branch target of a BLX instruction specially. (Reloc_stub::stub_type_for_reloc): Ditto. (Relocate::relocate): Use symbolic names instead of numeric relocation codes to report error. (Target_arm::do_relox): Reduce default stub-group size for Cortex-A8 workaround. * testsuite/Makefile.am (check_DATA): add thumb_blx_in_range.stdout, thumb_blx_out_of_range.stdout, thumb2_blx_in_range.stdout and thumb2_blx_out_of_range.stdout (thumb_bl_out_of_range, thumb_bl_out_of_range.o, thumb2_bl_out_of_range, thumb2_bl_out_of_range.o): Fix dependenices. (thumb_blx_in_range.stdout, thumb_blx_in_range, thumb_blx_in_range.o, thumb_blx_out_of_range.stdout, thumb_blx_out_of_range, thumb_blx_out_of_range.o, thumb2_blx_in_range.stdout, thumb2_blx_in_range, thumb2_blx_in_range.o, thumb2_blx_out_of_range.stdout, thumb2_blx_out_of_range, thumb2_blx_out_of_range.o): New rules. (MOSTLYCLEANFILES): Add thumb_blx_in_range, thumb_blx_out_of_range, thumb2_blx_in_range and thumb2_blx_out_of_range. * testsuite/Makefile.in: Regenerate. * arm_branch_in_range.sh: Add tests for THUMB BLX. * testsuite/thumb_blx_in_range.s: New file. * testsuite/thumb_blx_out_of_range.s: New file.
