Re: Doubt regarding dg-directives

[Krishna Narayanan <krishnanarayanan132002@gmail.com>]

Yes, it does.
I used dg-warning and not dg warning (that was a sheer typing mistake).
The warning is about the uninitialized variable being used in the
testcase yet there is no warning on that line and the test results in
FAIL.
I used /* { dg-warning "uninitialized" } */ on that particular line.I
used the test in gcc.dg, with other directive /* { dg-options "-O2" }
*/ .
Can you help me where I went wrong?
Thanks,
Krishna Narayanan
