[Simh] PDP-11 linux cross-assembler

2.11BSD's assembler, written in C, could be ported to gcc with some mechanical effort to turn the old K&R C to something that gcc only gripes about but will compile.

Subject: [Simh] PDP-11 linux cross-assembler

Hello,

I'm looking for a PDP-11 cross-assembler executable under linux/unix. I tried to generate a pdp11 target for gnu gas, but although the assembler seems to work, the linker does not understand the resulting object and aborts.

My "need" (to speak about "needing" something in a hobbyist environment is always relative) is to be able to generate binary/absolute PDP11 machine code to be directly loaded in the simh simulator via the "load" 
command. A C cross-compiler would also be nice to have, but at this moment I'm focused in assembly code.

Do you know about the existance of such a beast?

(If there is no unix cross-compiler, my preferences would be, in order, VMS and Windows)
