gcc/
* config.gcc (arm-wrs-vxworks): Remove dbxelf.h from tm_file.
Add vx-common.h. Include vxworks.h between vx-common.h and
arm/vxworks.h.
* config/vx-common.h (DWARF2_UNWIND_INFO): Undefine before
redefining.
* config/vxworks.h (TARGET_ASM_CONSTRUCTOR): Likewise.
(TARGET_ASM_DESTRUCTOR): Likewise.
* config/arm/vxworks.h (TARGET_OS_CPP_BUILTINS): Check arm_arch_xscale
instead of arm_is_xscale. Use VXWORKS_OS_CPP_BUILTINS.
(OVERRIDE_OPTIONS, SUBTARGET_CPP_SPEC): Define.
(CC1_SPEC): Add -tstrongarm. Line up backslashes.
(VXWORKS_ENDIAN_SPEC): Define.
(ASM_SPEC): Add VXWORKS_ENDIAN_SPEC.
(LIB_SPEC, STARTFILE_SPEC, ENDFILE_SPEC): Redefine to their
VXWORKS_* equivalents.
(LINK_SPEC): Likewise, but add VXWORKS_ENDIAN_SPEC.
(ASM_FILE_START): Delete.
(TARGET_VERSION): Reformat.
(FPUTYPE_DEFAULT, FUNCTION_PROFILER): Define.
(DEFAULT_STRUCTURE_SIZE_BOUNDARY): Define.
* config/arm/t-vxworks (LIB1ASMSRC, LIB1ASMFUNCS): Define.
(FPBIT, DPBIT): Define.
(fp-bit.c, dp-bit.c): New rules.
(MULTILIB_OPTIONS): Add strongarm, -mrtp and -mrtp/-fPIC multilibs.
(MULTILIB_MATCHES, MULTILIB_EXCEPTIONS): Define.
* config/arm/arm-protos.h (arm_emit_call_insn): Declare.
* config/arm/arm.h: Include vxworks-dummy.h.
* config/arm/arm.c (arm_elf_asm_constructor, arm_elf_asm_destructor):
Mark with ATTRIBUTE_UNUSED.
(arm_override_options): Do not allow VxWorks RTP PIC to be used
for Thumb. Force r9 to be the PIC register for VxWorks RTPs and
make it incompatible with -msingle-pic-base.
(arm_function_ok_for_sibcall): Return false for calls that might
go through a VxWorks PIC PLT entry.
(require_pic_register): New function, split out from...
(legitimize_pic_address): ...here. Do not use GOTOFF accesses
for VxWorks RTPs.
(arm_load_pic_register): Handle the VxWorks RTP initialization
sequence. Use pic_reg as a shorthand for cfun->machine->pic_reg.
(arm_emit_call_insn): New function.
(arm_assemble_integer): Do not use GOTOFF accesses for VxWorks RTP.
* config/arm/arm.md (UNSPEC_PIC_OFFSET): New unspec number.
(pic_offset_arm): New pattern.
(call, call_value): Use arm_emit_call_insn.
(call_internal, call_value_internal): New expanders.
* config/arm/lib1funcs.asm (__PLT__): Define to empty for
VxWorks unless __PIC__.
