I am building gcc for the vanilla Motorola m88k(not DG-UX) using the
Green Hills C compiler. I get through the first step, i.e. get gcc
built using Green Hills. Then when I use gcc to build itself (stage1?) 
using the -O option (optimizer on), the utilities "genflags", "gencodes",
etc. get bus errors when they are run. Using sdb to look at the core file
of "genflags", I discovered that the code at entry point, _start, which 
should be crt0.o is incorrect. It starts with an "xmem.bu" inst. When it
is correct it starts with a bunch of "or"s. 

If I remove the -O option when using gcc to build itself, then the gen*
utilities link & run fine. However, when the preprocssor cccp is built
and run, it dies with a signal 10(signal.h says this is bus error). 

Can anyone help??  Thanks.
