2010-09-03Re-apply r112883:Jim Grosbach
"For ARM stack frames that utilize variable sized objects and have either large local stack areas or require dynamic stack realignment, allocate a base register via which to access the local frame. This allows efficient access to frame indices not accessible via the FP (either due to being out of range or due to dynamic realignment) or the SP (due to variable sized object allocation). In particular, this greatly improves efficiency of access to spill slots in Thumb functions which contain VLAs." r112986 fixed a latent bug exposed by the above. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112989 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-03Check the local frame alignment for determining whether dynamic stackJim Grosbach
alignment should be performed. Otherwise dynamic realignment may trigger when the register allocator has already used the frame pointer as a general purpose register. That is, we need to make sure that the list of reserved registers doesn't change after register allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112986 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-03Finish converting the rest of the NEON VLD instructions to use pseudo-Bob Wilson
instructions prior to regalloc. Since it's getting a little close to the 2.8 branch deadline, I'll have to leave the rest of the instructions handled by the NEONPreAllocPass for now, but I didn't want to leave half of the VLD instructions converted and the other half not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112983 91177308-0d34-0410-b5e6-96231b3b80d8
