support for mova, and more responsible OS creation 2020-02-29 11:25:03 +01:00

start with the analysis passes
-> The cfg pass loads the function into memory, annotates leaders and
   jumps, and resolves delay slots.
-> The pcrel pass currently computes locations for pc-relative moves and
   jumps, but does not yet compute the pc-relative moved data.
-> The print pass displays the results of analysis with various layout
   and formatting options.

implement more of the meat of the tool
* Separate OS and Target conceptually; now an OS is created on an
  existing target which must have ROM bound.
* Add a configuration file with a data library and description files
  which are automatically loaded at startup.
* As a first application, implement target descriptions. It is now
  possible (given the proper library) to type [fxos info fx@3.10] to get
  information on the fx OS version 3.10.
* Set up the pass infrastructure and the first few easy passes. This
  is still a Work In Progress and not yet called from the command-line.
* Improve the copy/move behavior of classes (C++ concerns).
* Add instruction metadata, which will make it easier to write actual
  useful analysis passes.

Lephenixnoir d78f7bca10 initial system: instruction load, target creation
Contains basic stuff to start working:

* Loading files and assembly instruction descriptions
* Create a 64k-entry assembly decoding table
* Standard memory regions and information
* Create targets where files can be mapped at any addresses
* Load OSes and detect a few basic things
