[PATCH] D56663: [MSP430] Improve support of 'interrupt' attribute

[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added inline comments.

+  if (hasFunctionProto(D) && getFunctionOrMethodNumParams(D) != 0) {
+    S.Diag(D->getLocation(), diag::warn_msp430_interrupt_attribute)
----------------
What should happen if the function does not have a prototype? Should that be diagnosed? e.g., a K&R C function in C mode accepts an arbitrary number of arguments (which can include zero).
