Associate a MemOperand with LDWCP nodes introduced during ISel. This information is required if we want LDWCP to be hoisted out of loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139495 91177308-0d34-0410-b5e6-96231b3b80d8 2011-09-12 14:43:23 +00:00			`; RUN: llc < %s -march=xcore -asm-verbose=0 \| FileCheck %s`

Upgrade syntax of tests using volatile instructions to use 'load volatile' instead of 'volatile load', which is archaic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145171 91177308-0d34-0410-b5e6-96231b3b80d8 2011-11-27 06:54:59 +00:00			`store volatile i32 525509670, i32* %p, align 4`
