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
------------------------------

Here are the currently-expected SingleSource failures for V8
(Some C++ programs are crashing in libstdc++ at the moment;
I'm not sure why.)

  (llc) SingleSource/Regression/C++/EH/exception_spec_test
  (llc) SingleSource/Regression/C++/EH/throw_rethrow_test

Here are the currently-expected MultiSource failures for V8:

  (llc,cbe) MultiSource/Applications/d/make_dparser
  (llc,cbe) MultiSource/Applications/hexxagon
  (llc) MultiSource/Benchmarks/Fhourstones
  (llc,cbe) MultiSource/Benchmarks/McCat/03-testtrie
  (llc) MultiSource/Benchmarks/McCat/18-imp

  (llc,cbe) MultiSource/Benchmarks/Prolangs-C/plot2fig
  (llc,cbe) MultiSource/Benchmarks/Ptrdist/anagram
  (llc,cbe) MultiSource/Benchmarks/FreeBench/analyzer
    * DANGER * analyzer will run the machine out of VM
  (I don't know whether the following fail in cbe:)
  (llc) MultiSource/Benchmarks/FreeBench/distray

  (llc) MultiSource/Benchmarks/FreeBench/pifft
  (llc) MultiSource/Benchmarks/MallocBench/gs
  (llc) MultiSource/Benchmarks/Prolangs-C++/deriv1
  (llc) MultiSource/Benchmarks/Prolangs-C++/deriv2

Known SPEC failures for V8 (probably not an exhaustive list):

  (llc) 134.perl
  (llc) 177.mesa
  (llc) 188.ammp -- FPMover bug?
  (llc) 256.bzip2
  (llc,cbe) 130.li
  (native,llc,cbe) 126.gcc
  (native,llc,cbe) 255.vortex

To-do
-----

* support shl on longs (fourinarow needs this)
* support casting 64-bit integers to FP types (fhourstones needs this)
* support FP rem
