delete tool/instruction.rb (2nd try)
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@61784 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

Historically this option has been passed to the script. This is

supposedly because at the beginning the script was placed

outside of the ruby source tree. Decades passed since the merge

of YARV, now I can safely assume this feature is obsolescent.

Just ignore the passed value here.

This option used to override VM option that is defined in
