[Qemu-devel] QEMU as ISS (Instruction Set Simulator)

[??]

I am working on a project that requires me to modify the ISA of the MIPS 
target. I have been staring at the source code for about a week, but found it 
really difficult due to me being a young rookie and the sparse comments.
Specifically, I need to extend MIPS, by adding some new instructions and new 
CPU registers to the current architecture, and that sounds really easy. I think 
the place for me to look at should be at the directory 
${qemu_root}/target/mips/. With a MIPS Instruction Set Manual Release 6 handy, 
I have difficulty finding the source code where the ISA resides. Is it in 
op_helper.c? Or translate.c? Any guidance would be really appreciated. Thank 
you very much in advance.


Cheers,
L.
