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.)
