gcc/
* config.gcc (arm-wrs-vxworks*): Rework to handle arm-wrs-vxworks7 as
well as arm-wrs-vxworks. Update target_cpu_name from arm6 (arch v3) to
arm8 (arch v4).
* config/arm/vxworks.h (MAYBE_TARGET_BPABI_CPP_BUILTINS): New, helper
for TARGET_OS_CPP_BUILTIN.
(TARGET_OS_CPP_BUILTIN): Invoke MAYBE_TARGET_BPABI_CPP_BUILTINS(),
refine CPU definitions for arm_arch5 and add those for arm_arch6 and
arm_arch7.
(MAYBE_ASM_ABI_SPEC): New, helper for SUBTARGET_EXTRA_ASM_SPEC,
passing required abi options to the assembler for EABI configurations.
(EXTRA_CC1_SPEC): New macro, to help prevent the implicit production
of .text.hot and .text.unlikely sections for kernel modules when
using ARM style exceptions.
(CC1_SPEC): Remove obsolete attempt at mimicking Diab toolchain
options. Add EXTRA_CC1_SPEC.
(VXWORKS_ENDIAN_SPEC): Adjust comment and remove handling of Diab
toolchain options.
(DWARF2_UNWIND_INFO): Redefine to handle the pre/post VxWorks 7
transition.
(ARM_TARGET2_DWARF_FORMAT): Define.
* config/arm/t-vxworks: Adjust multilib control to removal of the
Diab command line options.
libgcc/
* config.host (arm-wrs-vxworks*): Rework to handle arm-wrs-vxworks7
as well as arm-wrs-vxworks.
* config/arm/t-vxworks7: New file. Add unwind-arm-vxworks.c to
LIB2ADDEH.
* config/arm/unwind-arm-vxworks.c: New file. Provide dummy
__exidx_start and __exidx_end for downloadable modules.
