Thanks. I'm working to port gcc to our chip. I use mips-elf as the

we don't have pc-region branch instructions such as 'j target'. So I'm
confused how to solve the function call translation. Thanks again.
If you don't have a jump to the full 4 gig address space take a look
at the ppc port.
It's probably best to use a branch stub in the linker (as is done in
binutils) instead of
the gcc work in the ppc backend, but that'll give you a place to start.
Ideally you'll just emit "branch foo" to get to a label and then have
the linker fix up
anything else.
Best of luck.
