There are a few classes of issues with disassembly tests. As the assembly tests are mainly a sanity check to ensure that the bytecode format is well properly understood, these issues are low priority.
- Formatting issues that do not effect semantics (differences in white spacing)
- Sometimes more operands are parsed then expected (cause unknown, perhaps padding interpreted as data).
- Printing literals with the wrong formatting
- Minimum precision annotations
- Float printing, FXC uses the standard printf float formatting that is difficult to replicate in C#. Assembly is normalized instead.
- Debug information is not support.
