[PATCH] D64908: Fix and test inter-procedural register allocation for ARM

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/include/llvm/CodeGen/TargetRegisterInfo.h:493
+  /// Return a null-terminated list of all of the registers thich are clobbered
+  /// "inside" a call to the given function. For example, these might be needed
+  /// for PLT sequences of long-branch veneers.
----------------
Why aren’t these explicit clobbers on the call itself?
