-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!

+Meta TODO list:
+1. Create a new DAG -> DAG instruction selector, by adding patterns to the
+   instructions.
+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.
