[RFC PATCH 0/6] some vxworks/powerpc patches

[Rasmus Villemoes <rasmus dot villemoes at prevas dot dk>]

These are some of the patches I'm currently applying to get a full C
and C++ compiler to work for powerpc-wrs-vxworks (for vxworks
5.5). With these, and a few more, I have ZCX, static
constuctors/destructors and throwing across modules working. There are
many vxworks variants out there, so I'm not sure how to avoid breaking
things for others. I don't really like the crti hack, but I don't have
any better ideas (I can probably patch the loader to recognize even
symbols of type unknown, but that won't benefit anybody else, so I'm
trying to fix problems in gcc whenever possible).

Rasmus Villemoes (6):
  vxworks: add target/h/wrn/coreip to the set of system include paths
  libgcc: add crt{begin,end} for powerpc-wrs-vxworks target
  vxworks: enable use of .init_array/.fini_array for cdtors
  powerpc/vxworks: [hack] add crti.o file
  powerpc/vxworks: add {START,END}FILE_SPEC for
    HAVE_INITFINI_ARRAY_SUPPORT
  vxworks: don't define vxworks_asm_out_constructor when using
    .init_array
