Sure, it would update many tests, but that would be better I suppose to see what happens.


================
Comment at: llvm/test/Transforms/LoopVectorize/X86/vector_ptr_load_store.ll:1
-; RUN: opt -passes=loop-vectorize -mcpu=corei7-avx -debug -S < %s 2>&1 | FileCheck %s
+; RUN: opt -passes=loop-vectorize -mcpu=corei7-avx -debug-only=loop-vectorize -S < %s 2>&1 | FileCheck %s
 ; REQUIRES: asserts

With the `-debug` flag it was printing out the interleaved groups as well, which I felt takes away focus from the main check lines.
