Changes in directory llvm/lib/Target/PowerPC:
PPCInstrInfo.td updated: 1.239 -> 1.240
---
Log message:
bswapped load/store instructions are only availble in indexed addressing form.
As such, use xoaddr (indexed only), not xaddr for address selection.
This fixes CodeGen/PowerPC/2006-07-19-stwbrx-crash.ll, a crash compiling lencod.
