[Qemu-devel] [PATCH 0/4] target-sparc: More CC cleanups

[Richard Henderson <rth@twiddle.net>]

The first patch is a bug fix for the previous series,
already posted. 
  
The second patch improves the common cases of using
andcc or orcc to test bits in a register.  It also
just so happens to show potential cleanup value in
the ALWAYS and NEVER conditions.  ;-)

The third patch is one that I thought I'd included in
the previous series, but which got lost during rebasing.
 
The last patch is worth an incredible 30% speedup to
generated code, as measured by sparc64 cc1plus run on
a somewhat large input file.
