Display annotated disassembly

[philipc]

Display the disassembled instructions for each function, and annotate with information from the DWARF. Desired information:

• variables associated with operands of instructions
• file/line, and inlined function if applicable

Optimization is going to make this hard to display in a sensible manner, but I'm hopeful at least some useful information is possible.

This probably requires HTML output to be usable (see #4).

Feel free to crib code from (or massage the code into a reusable crate) my rust-disasm work:

Thanks, but I'm already doing disassembly in this crate using panopticon (I use it to find function calls). I need to stick with using panopticon for disassembly; capstone's semantic info is lacking.

I've switched to capstone. Still not convinced its semantic info is complete enough, but it handles what I need so far, and it is more reliable.

ddbug can now output basic disassembly with CFI directives.
