* Better handling of dead super registers in LiveVariables. We used to do this:Jakob Stoklund Olesen2010-03-052-22/+22

[not using %RAX] %EAX = ... RET %EAX<imp-use,kill> By not artificially keeping %RAX alive, we lower register pressure a bit. The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously 55, anybody can see that.

* Reworking the stack layout that the MicroBlaze backend generates.Wesley Peck2010-03-056-61/+257
| | | | | | | | | | | | | The MicroBlaze backend was generating stack layouts that did not conform correctly to the ABI. This update generates stack layouts which are closer to what GCC does.
