Disassembler for Toshiba microcontroller used in 1990s Toyota ECU. Notably,
3S-GTE engine in MR2 and Celica is based on this controller.
Iterative workflow (take disassembler output, add symbols and directives and feed to disassembler)
Code location discovery via branch/call tracing (is this useful considering computed branches won't work?)
