-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!

+1. Create a new DAG -> DAG instruction selector, by adding patterns to the

+2. ???
+3. profit!
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
-

+* Keep the address of the constant pool in a register instead of forming its
+ address all of the time.
+* We can fold small constant offsets into the %hi/%lo references to constant
+ pool addresses as well.
