needs to be examined more closely:
- The stack layout needs to be examined to make sure it meets
the standard, especially in regards to var arg functions.
- - The processor itineraries are copied from a different backend
- and need to be updated to model the MicroBlaze correctly.
- Look at the MBlazeGenFastISel.inc stuff and make use of it
if appropriate.
There are a few things that need to be looked at:
- There are some instructions that are not generated by the backend
and have not been tested as far as the parser is concerned.
- - The assembly parser does not use any MicroBlaze specific directives.
+ - The assembly parser does not use many MicroBlaze specific directives.
I should investigate if there are MicroBlaze specific directive and,
if there are, add them.
- - The instruction MFS and MTS use special names for some of the
- special registers that can be accessed. These special register
- names should be parsed by the assembly parser.
