Take a look at trunk/rtl/linux/mips/prt0.as
This file is non-functional, but it seems to contain some disassembly
of a start code (probably from some other compiler...)
This disassembly syntax seems quite different from
the other assembler code (below in same file and in other sources
seem more like gnu as generated by GCC if using --save-temps.
Well, at least register naming is different (using a4 or s7 instead of $sp
where X is a number...)
Anyway, maybe the content of rtl/mips/prt0.as isn't really MIPS assembler at
