Subject: Add an error diagnostic to Parse::ParseObjCMessageExpression().
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=11508212aacde5199b0475a578a481febf5dc067;p=clang

Add an error diagnostic to Parse::ParseObjCMessageExpression().

This now exposes the following bug...

******************** TEST 'Sema/message.m' FAILED! ********************
Command:
 clang -fsyntax-only -verify Sema/message.m
Output:
Errors seen but not expected:
  Line 9: invalid receiver to message expression
******************** TEST 'Sema/message.m' FAILED! ********************

As far as I can tell, all messages to method agruments fail.

The method arguments are built by Sema::ObjcActOnStartOfMethodDef().
