                        Instruction analysis program

This application reads in a binary list of instructions, and analyses it with a

set of functions looking at various parameters in each instruction.

It has been designed so a different instruction set support can be added.

Right now it's not so user friendly. Everything is hardcoded, and only support

for the OR1K instruction set exists.

Compile the program with:

$ make all

And run a test (it needs the or32-elf- toolchain) with:

$ make test

To run the program itself, just give it a binary blob of instructions (usually

the output of objcopy -O binary).

For instance the Linux kernel ELF can be prepared with the following command:

$ or32-elf-objcopy -O binary -j .text -S vmlinux vmlinux.text.bin

Run it in the program with

$ ./insnanalysis vmlinux.text.bin > vmlinux.insnanalysis

Currently the program will output all appropriate information for each

instruction (ie. only ones with rA, or immediate fields in the instructions will

have reports on those fields.)

TODO:

 o Add a more flexible way of indicating the instructions to dump

 o Add an easy way to switch between human readable and CSV output

 o Figure out how to tack this thing onto a simulator (or1ksim maybe) to give

   results of execution when that finishes executing, or just how to get the

   simulator to output a binary dump of executed instructions to be fed through

   this

 o Instruction group analysis (pairs, triplets, etc.)
