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:
UnitTests/SetjmpLongjmp/C++/C++Catch
UnitTests/SetjmpLongjmp/C++/SimpleC++Test
UnitTests/2003-05-07-VarArgs
UnitTests/2003-08-11-VaListArg

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
