           Summary: No warning when reaching end of a non-void function.
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: richard.smith at antixlabs.com
                CC: llvmbugs at cs.uiuc.edu


$ cat foo.c
int foo() {}
$ gcc foo.c -c -Wall
foo.c: In function ‘foo’:
foo.c:1: warning: control reaches end of non-void function
$ llvm-gcc foo.c -c -Wall
$

In gcc that warning comes out of the tree optimisation passes, which llvm does
not use. It would be nice if it did an equivalent check, though.
