dithumb

A demo ARM/Thumb disassembler. Given an ARM ELF file as input, we look into the symbol table for ARM code mapping symbols, namely, $a, $t, and $d. Available instructions are disassembled based on code symbols and printed to stdout. When symbol table is not found, disassmebly is done using linear sweep similar to objdump.

Additionally, the tool displays some useful statistics such as the number of basic blocks, direct jumps and indirect jumps found in the binary.

Trying it

Build the project and try it on one of the binaries available here, for example:

./dithumb -t -f coreutils/echo

It's possible to use linear sweep directly using -l option.

Dependencies

The project depends on Capstone disassembly library.
