Hmm, thanks Oliver. The entire Thumb1 rewriteFrameIndex looks more and more dodgy as I look at it. I'm almost sure I could make it overwrite CPSR too.
I'm also getting more convinced that we do want to try and align local variables to 32-bits if possible, though the code should be able to cope without. Even if DataLayout isn't the way to handle this.
I might get a point fix working today, but I think I need to do some more work here.
Cheers.
Tim.
