delete tool/instruction.rb
Previous commit changed insns.def format. Now is the time for its
generators. In doing so I chose to modernize the system, not just
patch. My attempt includes
- extensive use of Onigumo regular expressions
- split from one big file (instruction.rb) into separated MVC
- partial view
Also, let me take this opportunity to kill old unused features
such as
- stack caching
- minsns / yasmdata which are never seriously used
- yarvarch document generation (moved to doc/)
- vast majority of unused arguments to insns2vm.rb
This commit generates VM source codes that cleanly compile, and
the generated binary passes tests. At least for me.
