Bob Wilson d4bfd54ec2 Change ARM VFP VLDM/VSTM instructions to use addressing mode #4, just like ... all the other LDM/STM instructions. This fixes asm printer crashes when compiling with -O0. I've changed one of the NEON tests (vst3.ll) to run with -O0 to check this in the future. Prior to this change VLDM/VSTM used addressing mode #5, but not really. The offset field was used to hold a count of the number of registers being loaded or stored, and the AM5 opcode field was expanded to specify the IA or DB mode, instead of the standard ADD/SUB specifier. Much of the backend was not aware of these special cases. The crashes occured when rewriting a frameindex caused the AM5 offset field to be changed so that it did not have a valid submode. I don't know exactly what changed to expose this now. Maybe we've never done much with -O0 and NEON. Regardless, there's no longer any reason to keep a count of the VLDM/VSTM registers, so we can use addressing mode #4 and clean things up in a lot of places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112322 91177308-0d34-0410-b5e6-96231b3b80d8		2010-08-27 23:18:17 +00:00
