[XCore] Convert a couple of tests to FileCheck. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179619 91177308-0d34-0410-b5e6-96231b3b80d8 2013-04-16 19:41:19 +00:00			`; RUN: llc < %s -march=xcore \| FileCheck %s`
Custom lower unaligned 32 bit stores and loads into libcalls. This is a big code size win since before they were expanding to upto 16 instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75901 91177308-0d34-0410-b5e6-96231b3b80d8 2009-07-16 10:21:18 +00:00

Expand unaligned 32 bit loads from an address which is a constant offset from a 32 bit aligned base as follows: ldw low, base[offset >> 2] ldw high, base[(offset >> 2) + 1] shr low_shifted, low, (offset & 0x3) * 8 shl high_shifted, high, 32 - (offset & 0x3) * 8 or result, low_shifted, high_shifted Expand 32 bit loads / stores with 16 bit alignment into two 16 bit loads / stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75902 91177308-0d34-0410-b5e6-96231b3b80d8 2009-07-16 10:42:35 +00:00
