catch me if I try to use a pointer to an empty struct as a key in

much better than sometimes corrupting data (and other times working
fine) due to insufficient alignment.

It also means that we will be much more diligent about rejecting other
uses of these constructs that aren't safe.

It also means that we can now be more aggressive with the constructs
when we actually have guaranteed higher alignment without specializing
stuff. I'll be going through and cleaning up all the current overrides

6 years ago[lit] Implement support of per test timeout in lit.
Dan Liew [Sun, 27 Dec 2015 14:03:49 +0000 (14:03 +0000)]
[lit] Implement support of per test timeout in lit.

This should work with ShTest (executed externally or internally) and GTest
test formats.

To set the timeout a new option ``--timeout=`` has
been added which specifies the maximum run time of an individual test
in seconds. By default this 0 which causes no timeout to be enforced.

The timeout can also be set from a lit configuration file by modifying
the ``lit_config.maxIndividualTestTime`` property.

To implement a timeout we now require the psutil Python module if a
 timeout is requested. This dependency is confined to the newly added
 ``lit.util.killProcessAndChildren()``. A note has been added into the
 TODO document describing how we can remove the dependency on the
 ``pustil`` module in the future. It would be nice to remove this
 immediately but that is a lot more work and Daniel Dunbar believes it is
better that we get a working implementation first and then improve it.

To avoid breaking the existing behaviour the psutil module will not be
imported if no timeout is requested.

The included testcases are derived from test cases provided by
 Jonathan Roelofs which were in an previous attempt to add a per test
 timeout to lit (http://reviews.llvm.org/D6584). Thanks Jonathan!

Chandler Carruth [Sun, 27 Dec 2015 08:41:34 +0000 (08:41 +0000)]
[attrs] Extract the pure inference of function attributes into
a standalone pass.

There is no call graph or even interesting analysis for this part of
function attributes -- it is literally inferring attributes based on the
target library identification. As such, we can do it using a much
simpler module pass that just walks the declarations. This can also
happen much earlier in the pass pipeline which has benefits for any
number of other passes.

In the process, I've cleaned up one particular aspect of the logic which
was necessary in order to separate the two passes cleanly. It now counts
inferred attributes independently rather than just counting all the
inferred attributes as one, and the counts are more clearly explained.

The two test cases we had for this code path are both ... woefully
inadequate and copies of each other. I've kept the superset test and
updated it. We need more testing here, but I had to pick somewhere to
stop fixing everything broken I saw here.
