[PATCH] D59547: [X86] Remove X86 specific dag nodes for RDTSC/RDTSCP/RDPMC. NFCI

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: lib/Target/X86/X86ISelLowering.cpp:22813
+    assert(N->getNumOperands() == 3 && "Unexpected number of operands!");
+    Chain = DAG.getCopyToReg(Chain, DL, SrcReg, N->getOperand(2));
+  }
----------------
I wonder if this should be glued to the MachineNode?
