   2 SparcV8 backend skeleton
   3 ------------------------
   4
   5 This directory houses a 32-bit SPARC V8 backend employing a expander-based
   6 instruction selector.  It is not yet functionally complete.  Watch
   7 this space for more news coming soon!

  12 All SingleSource/Benchmarks tests are expected to pass.  Currently, all
  13 C++ tests and all tests involving varargs intrinsics (use of
  14 va_start/va_end) are expected to fail.  Here are the known SingleSource
  15 failures:

  32 To-do
  33 -----
  34
  35 * support setcc on longs
  36 * support basic binary operations on longs
  37   - use libc procedures instead of open-coding for:
  38     __div64 __mul64 __rem64 __udiv64 __umul64 __urem64
  39 * support casting 64-bit integers to FP types
  40 * support varargs intrinsics (va_start et al.)
