egcc on mips-dec-ultrix4.4

[Burkhard Steding]

Hi,

I think the definition of INITIALIZE_TRAMPOLINE in gcc/config/mips/mips.h
is wrong:

#define INITIALIZE_TRAMPOLINE(ADDR, FUNC, CHAIN)			    \
{ .......								    \
  emit_library_call (gen_rtx (SYMBOL_REF, Pmode, "_flush_cache"),	    \
  .......								    \
}

On Ultrix 4.4 (and probably older versions too) there is no _flush_cache()
in the system libraries. Older versions of gcc did:

#define INITIALIZE_TRAMPOLINE(ADDR, FUNC, CHAIN)			    \
{ .......								    \
  emit_library_call (gen_rtx (SYMBOL_REF, Pmode, "cacheflush"),		    \
  .......								    \
}

This works since there is cacheflush() in libc.a.
Possible solutions are to #ifdef DECSTATION this in gcc/config/mips/mips.h
or to #undef INITIALIZE_TRAMPOLINE and redefine in gcc/config/mips/ultrix.h.
