llvm-mirror/test/CodeGen/AVR/directmem.ll
Dylan McKay 9f3b55d70a [AVR] Reorder the CHECK lines in directmem.ll to match current trunk 
In r346432 ("[DAGCombine] Improve alias analysis for chain of independent stores"),
the order of ldi/sts blocks changed.

The new IR is equivalent to the old IR.

This patch updates the test to fix the test suite.
