SparcV8 backend skeleton
|
|
------------------------
|
|
|
|
This directory houses a 32-bit SPARC V8 backend employing an expander-based
|
|
instruction selector. It is not yet functionally complete. Watch
|
|
this space for more news coming soon!
|
|
|
|
Current expected test failures
|
|
------------------------------
|
|
|
|
All SingleSource/Benchmarks tests are expected to pass. Currently, all
|
|
C++ tests and most tests involving varargs instructions
|
|
(e.g. vaarg) are expected to fail. Here are the known SingleSource
|
|
failures:

To-do
|
|
-----
|
|
|
|
* support setcc on longs
|
|
* support basic binary operations on longs
|
|
- use libc procedures instead of open-coding for:
|
|
__div64 __mul64 __rem64 __udiv64 __umul64 __urem64
|
|
* support casting 64-bit integers to FP types
|
|
* fully support varargs instructions
