* Fix a bug that caused the pass to go into infinite loops on trivial testcases.Chris Lattner2004-08-161-1/+2

| | | | llvm-svn: 15808
* Fix frame pointer handling:Nate Begeman2004-08-162-32/+33
| | | | | | | | | | Reserve R0 in store/load from stack slot for building >32k offsets from SP or FP. This also requires we use R11 rather than R0 for holding the LR value we want to save or restore. Also, tell the register allocator not to use R31 (our FP) in functions that have a frame pointer. These changes fix Burg. llvm-svn: 15807
