-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 are expected to fail.  Here are the known SingleSource failures:
-
-       UnitTests/SetjmpLongjmp/C++/C++Catch
-       UnitTests/SetjmpLongjmp/C++/SimpleC++Test
-       Regression/C++/EH/ConditionalExpr
-       Regression/C++/EH/ctor_dtor_count-2
-       Regression/C++/EH/ctor_dtor_count
-       Regression/C++/EH/exception_spec_test
-       Regression/C++/EH/function_try_block
-       Regression/C++/EH/simple_rethrow
-       Regression/C++/EH/simple_throw
-       Regression/C++/EH/throw_rethrow_test
-       CustomChecked/oopack_v1p8
+Meta TODO list:
+1. Create a new DAG -> DAG instruction selector, by adding patterns to the
+   instructions.
+2. ???
+3. profit!
 
 To-do
 -----
 
-* support setcc on longs
-* support shifts on longs
-* support casting 64-bit integers to FP types
-* support FP rem

+* 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.
