[PATCH] D100581: [Clang] -Wunused-but-set-parameter and -Wunused-but-set-variable

[Nick Desaulniers via Phabricator via cfe-commits]

nickdesaulniers added a comment.

I see lots of instances from the kernel that look like this when reduced:

  $ cat foo.c
  int page;
  int put_page_testzero(int);
  void foo (void) {
    int zeroed;
    zeroed = put_page_testzero(page);
    ((void)(sizeof(( long)(!zeroed))));
  }
  $ clang -c -Wall foo.c
  foo.c:4:7: warning: variable 'zeroed' set but not used [-Wunused-but-set-variable]
    int zeroed;
        ^
