-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!
-
-Current expected test failures
-------------------------------
-
-All SingleSource/Benchmarks tests are expected to pass. Currently, all
-C++ tests and all tests involving varargs intrinsics (use of
-va_start/va_end) 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

+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 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
-* support varargs intrinsics (va_start et al.)
-
-$Date$
+* 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.
