[PATCH] D81586: [ARM] Describe defs/uses of VLLDM and VLSTM

[Eli Friedman via Phabricator via llvm-commits]

efriedma added inline comments.


================
Comment at: llvm/lib/Target/ARM/ARMExpandPseudoInsts.cpp:1280
+  for (int I = 0; I < 7; ++I)
+    VLSTM.addReg(ARM::Q0 + I, RegState::Implicit | RegState::Undef);
 
----------------
RegState::Undef seems wrong: presumably the registers may actually contain data we need to preserve, or we wouldn't bother saving them in the first place.
