gcc version 4.4.0 20081020 (experimental) [trunk revision 141240] (GCC)
I get this error:
[descartes:gcc/objdirs/gambc-v4_1_2] lucier% /pkgs/gcc-4.4.0-64/bin/gcc

gcc: unrecognized option '-no-cpp-precomp'
assemtest.s:69:Parameter error: expression must be a multiple of 4 (parameter
2)
The offending assembler command is
ldu r0,7(r9)
I'll include assemtest.i; the code itself is about 50 lines of
machine-generated C code, plus a lot of declarations so I could get it to
compile separately.
