--- Comment #2 from Bill Wendling <wendling at apple.com> ---

Compiler-RT change:

Sending        lib/profile/GCDAProfiling.c
Transmitting file data .
Committed revision 177337.

LLVM change:

Sending        Instrumentation/GCOVProfiling.cpp
Transmitting file data .
Committed revision 177340.

Note: With the example below, there will still be no lines executed in main.c,
because the 'foo()' function never returns (and thus never gets counted). To
show that it is indeed being run, add this to the top of `main()':

  for (int i = 0; i < 1; ++i)
    printf("hello world!\n");
