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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61733 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
