[PATCH] D131424: Remove the unused/undefined _cmd parameter to objc_direct methods.

[Puyan Lotfi via Phabricator via cfe-commits]

plotfi added a comment.

I tried running the following on some example code and got a stacktrace:

  // RUN: clang -cc1 -no-opaque-pointers -emit-llvm -fobjc-arc -triple x86_64-apple-darwin10 -o - %s  -O0
  
  @interface C
  - (int)getInt __attribute__((objc_direct));
  @end
  
  @implementation C
  - (int)getInt __attribute__((objc_direct)) {
  }
  @end
  
  void f() {
    C *c;
    [c getInt];
  }
