[PATCH] D44782: Account for partial stack slot spills (PR30821)

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: lib/Target/X86/X86InstrInfo.cpp:4270
+  case X86::VMOVDQU16Z256mr:
+    MemBytes = RegSize;
     return true;
----------------
Why can't we always get this from the opcode or always from RegSize? What's the criteria for which way this is done? Why are the KMOV instructions implemented differently between Load and Store?
