Assembler errors with --host=m68k-motorola-sysv3

[Beere, Chris]

Hello,
         I have been trying to upgrade our gnu C compiler from 2.4.5 to
2.95.2 and have been having a lot of problems. I originally had an internal
compiler error and reported this too you, subject line:-

genattr: Internal compiler error in `read_rtx', at
../../src/gcc-2.95.2/gcc/rtl.c:888

Since then I have installed an old compiler 2.7.2.3 and tried the compile of
2.95.2 again. It failed immeditely in the assembler, which is gas from
binutils 2.9.1 with the following errors:-

(hilda)# make bootstrap

which has the operands the wrong way round for gas
cmp.b %d0,&34  should be cmp.b &34,%d0

I f I force it to use the native assembler /bin/as the build progresses
smoothly until:-

Please note in the first build the compilation line does not contain any
references to gas but in the second -DUSE_GAS is used to tell it to use GAS
format.
My configure command was "configure --host=m68k-motorola-sysv3 --with-gnu-as
--with-gnu-ld"

It seems to me as though --with-gnu-as is not having the desired effect?
What could be wrong? Is there a magic environment variable I have not set
up? I have set up "CC=gcc;export CC". I need to be able to use gas as the
native assembler can't cope with cccp.c.

Any ideas as to why gcc is not taking any notice of --with-gnu-as? Do the
the older compilers need a different option like --with-gas?
