This patch adds three new arguments to validate_failures.py so
it can be used outside the build directory:
--ignore_missing_failures
When a failure is expected in the manifest but it is not found in
the actual results, the script produces a note alerting to this
fact. This means that the expected failure has been fixed, or it
did not run, or it may simply be flaky.
With this option, one can ask the script not to show the missing
failures.
--manifest
Name of the manifest file to use. By default, the script will
look for the manifest file in the source directory associated with
this build. With this option, one can point to any arbitrary
manifest file. I renamed the old --manifest flag to
--produce_manifest.
--results
Space-separated list of .sum files with the testing results to
check. The only content needed from these files are the lines
starting with FAIL, XPASS or UNRESOLVED.

The location for a built-in macro token is BUILTIN_LOCATION. When we
see that location value, we cannot know if that token was used in a
system header or not. And that can trigger some unwanted warnings on
e.g, the use of __LONG_LONG_MAX__ built-in macro in system headers
when we compile with -pedantic, like in the test case accompanying
this patch.
In that case, I think we ought to step-up to see where the built-in
macro has been expanded, until we see a location that is not for a
built-in macro. Then we can check if the resulting location is in a
system header or not.
Now that we step up to the location of first non-built-in-macro token,
it appeared that for
testsuite/c-c++-common/dfp/convert-int-saturate.c, G++ then fails to
emit the warning in:
volatile unsigned int usi;
int
main ()
{
usi = DEC32_MAX; /* { dg-warning "overflow in implicit constant conversion" } */
...
}
Because DEC32_MAX is defined in the system header float.h as a
built-in macro:
#define DEC32_MAX __DEC32_MAX__
And during the parsing of the assignment expression that should have
led to the warning above, input_location is set to the location for
the DEC32_MAX, which is actually the location for the built-in
__DECL32_MAX_EXP.
A possible fix is to use the location of the "=" operator as the
default location for assignment expressions. This is what the patch
does.
I had to adjust a couple of tests to arrange for this.
Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.
