Assertions on invalid 8bit assembler operations
-----------------------------------------------

                 Key: RVM-829
                 URL: http://jira.codehaus.org/browse/RVM-829
             Project: RVM
          Issue Type: Improvement
          Components: Instruction Architecture: Intel
            Reporter: Ian Rogers
             Fix For: 1000


It's very easy to get burnt by the difference between 8bit and 32bit registers on Intel, for example "setnz edi" isn't a real instruction. MRP has a patch to fail assertions if these instructions ever get generated, it's worth the RVM also picking them up from MRP-9:
