[PATCH] Add/update VxWorks targets for ld

Phil Edwards phil@codesourcery.com
Thu Oct 23 22:39:00 GMT 2003 
The new targets recently added to GCC also require corresponding changes in
binutils.  This is the patch and changelog for the ld directory.  (I do not
have write access.  Also, while I've regenerated Makefile.in here, whoever
does the commit will need to regen it there.)


2003-10-23  Phil Edwards  <phil@codesourcery.com>

	* Makefile.am (ALL_EMULATIONS): Add elf32mipswindiss.o.
	(eelf32mipswindiss.c): New target.
	* Makefile.in:  Regenerated.
	* emulparams/elf32mipswindiss.sh:  New file.
	* configure.tgt (i[3-7]86-*-vxworks*, arm-*-vxworks, sh-*-vxworks,
	mips*-*-vxworks*):  Use ELF now.
	(mips*-*-windiss):  New stanza, use elf32mipswindiss.
