SparcV8 backend skeleton
------------------------
This directory houses a 32-bit SPARC V8 backend employing a expander-based
instruction selector. It is not yet functionally complete. Watch
this space for more news coming soon!

To-do
-----
* support calling functions with more than 6 args
* support 64-bit integer (long, ulong) arguments to functions
- use libc procedures instead of open-coding for:
__div64 __mul64 __rem64 __udiv64 __umul64 __urem64
* support setcc on longs
* support basic binary operations on longs
* support casting <=32-bit integers, bools to long
* support casting 64-bit integers to FP types
* support varargs intrinsics (va_start et al.)
