[PATCH] D31643: ARMFrameLowering: Reserve emergency spill slot for large arguments

[Tim Northover via Phabricator via llvm-commits]

t.p.northover added inline comments.

Comment at: lib/Target/ARM/ARMFrameLowering.cpp:340
+  // r12?) saved to reach FP.
+  return -AFI.getArgRegsSaveSize() - 12;
+}
----------------
Should this be ArgumentStackSize too? I think ArgRegsSaveSize only accounts for when R0-R3 get pushed on function entry.
