[PATCH] D127115: [RFC][DAGCombine] Make sure combined nodes are added back to the worklist in topological order.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/test/CodeGen/X86/sse41.ll:1160
 
+; FIXME: This could be 'pshufb {{.*#+}} xmm0 = xmm0[12,13,14,15],zero,zero,zero,zero,zero,zero,zero,zero,xmm0[12,13,14,15]'
+
----------------
Drop this - pshufb probably isn't a perf gain. These tests are more about folding to insertps
