My questions are here,as following: 1.whether the schedule of an instruction defines the machine how to do. 2.Why is there no "add" or "sub" instructions("ALU insturctions") in X86InstrArithmetic.td? How "ALU insturctions" define? 3. I use the WriteIMul32Reg in my insturction.In my imagination, my instruction should also be multiplication.But it doesn't work.(my instruction can be compiled but can't run) .why can't it run? I think, it'...

Hello, Can anyone please help me with the following issue I am running rspec-rails 1.3.2 with rails 2.3.9 on ruby 1.8.7 Unfortunately my tests don''t execute at all after i updated these gems although i followed the update insturctions. After some debugging i found that the describes and examples get created, but they never get registered with ExampleGroupFactory.add_example_group and therefore not executed when runner.run is called This seems to be a rspec-rails issue only as i could execute the tests for rspec 1.3.0 the gems...

Sorry, but this is really NOT as easy as the tutorials/books make out. I''m really struggling at the first hurdle here. And while I''m not a programmer by design I do know my way around most stuff. And if I can''t get this to work I suspect more people will have the same issues. There seems to be too many variables to address. I have winXP, I have ruby and rails all
