Subject: Use new CHECK-DAG support to stabilize CodeGen/PowerPC/recipest.ll
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=0d6423b4762be62966c1941738f5284e35c93b65;p=oota-llvm.git

Use new CHECK-DAG support to stabilize CodeGen/PowerPC/recipest.ll

While testing some experimental code to add vector-scalar registers to
PowerPC, I noticed that a couple of independent instructions were
flipped by the scheduler.  The new CHECK-DAG support is perfect for
avoiding this problem.
