New x86 target

[Chet Simpson]

I am looking to target GCC to a new x86 platform and would very much
like to determine what work has already been done which may assist in
creating a new build target. The target OS expects that EBX contain a
pointer to the processes global storage area (data segment if you will)
and that the first parameter is passed in EAX. Additionally, I would
like include an option that would allow the generated assembler to
access globals from an effective address off the instruction pointer.

Are there any existing x86 targets which include some of these behaviors
or that would be a prime candidate for the base of these additions?
