-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,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/fourinarow
-  (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 (call fmod)
-
+* open code 64-bit shifts
 * Keep the address of the constant pool in a register instead of forming its
   address all of the time.
-
-* Change code like this:
-        or      %o0, %lo(.CPI_main_0), %o0
-        ld      [%o0+0], %o0
-  into:
-        ld	[%o0+%lo(.CPI_main_0)], %o0
-  for constant pool access.
-
 * We can fold small constant offsets into the %hi/%lo references to constant
   pool addresses as well.
 
-* Directly support select instructions, and fold setcc instructions into them
-  where possible.  I think this is what afflicts the inner loop of Olden/tsp
-  (hot block = tsp():no_exit.1.i, overall GCC/LLC = 0.03).
