Introduce vxworks specific crtstuff support
2019-11-06 Jerome Lambourg <lambourg@adacore.com>
Olivier Hainque <hainque@adacore.com>
libgcc/
* config/vxcrtstuff.c: New file.
* config/t-vxcrtstuff: New Makefile fragment.
* config.host: Append t-vxcrtstuff to the tmake_file list
on all VxWorks ports using dwarf for table based EH.
gcc/
* config/vx-common.h (USE_TM_CLONE_REGISTRY): Remove
definition, pointless with a VxWorks specific version
of crtstuff.
(DWARF2_UNWIND_INFO): Conditionalize on !ARM_UNWIND_INFO.
* config/vxworks.h (VX_CRTBEGIN_SPEC, VX_CRTEND_SPEC):
New local macros, controlling the addition of vxworks specific
crtstuff objects depending on the EH mechanism and kind of
module being linked.
(VXWORKS_STARTFILE_SPEC, VXWORKS_ENDFILE_SPEC): Use them.
