[LLVMdev] Sparc back end fix

[Timothy M Jones]

Hi everyone,

Following my earlier posting  
(http://lists.cs.uiuc.edu/pipermail/llvmdev/2010-November/036292.html), I  
sent another message to the list, but it seems like it didn't get through  
:-(  I managed to fix the problem in my earlier post and compile a  
cross-llvm-gcc.  Then I discovered I was having problems with a setting a  
variable based on a ?: condition.  Anyway, I've managed to track down the  
problem which was due to the conditional move not declaring its implicit  
use of the icc register in the back end.  The following patch fixes this  
problem.  A test case is also provided here too.

Cheers
Tim
