The tests for the disassembler were adapted from the encoder tests, and for the most part, the output from the disassembler matches that encoder-test inputs. There are some places where more-informative mnemonics could be produced (notably for the branch instructions), and those cases are noted in the tests with FIXMEs. Future work includes: - Generating more-informative mnemonics when possible (this may also be done in the printer). - Remove the dependence on positional "numbered" operand-to-variable mapping (for both encoding and decoding). - Internally using 64-bit instruction variants in 64-bit mode (if this turns out to matter). llvm-svn: 197693
