The `shtest-timeout.py` test was failing intermittently. It looks like
the issue is that on a resource constrained system lit is unable to run
`quick_then_slow.py` twice and print out the messages the tests expects
within the one second timeout.
The underlying issue is that the test is dependent on the performance of
the host machine is a rather fragile way. This is due to hardcoding
timeout values and having assumptions that the host machine is able to
perform a certain amount of work within the hardcoded timeout values.
We could increase the timeout values but that doesn't really fix the
underlying issue. Instead this patch removes one of fragile assumptions
in the hope that this will be enough to fix the bots.
There are other fragile assumptions in this test (e.g. `quick.py` can be
executed in less than 1 second). If the bots continue to fail we'll have
to revisit this.

Summary:
These changes are to allow to a Result object to have nested Result objects in
order to support microbenchmarks. Currently lit is restricted to reporting one
result object for one test, this change provides support tests that want to
report individual timings for individual kernels.
This revision is the result of the discussions in
https://reviews.llvm.org/D32272#794759,
https://reviews.llvm.org/D37421#f8003b27 and https://reviews.llvm.org/D38496.
It is a separation of the changes purposed in https://reviews.llvm.org/D40077.
This change will enable adding LCALS (Livermore Compiler Analysis Loop Suite)
collection of loop kernels to the llvm test suite using the google benchmark
library (https://reviews.llvm.org/D43319) with tracking of individual kernel
timings.
Previously microbenchmarks had been handled by using macros to section groups
of microbenchmarks together and build many executables while still getting a
grouped timing (MultiSource/TSVC). Recently the google benchmark library was
added to the test suite and utilized with a litsupport plugin. However the
limitation of 1 test 1 result limited its use to passing a runtime option to
run only 1 microbenchmark with several hand written tests
(MicroBenchmarks/XRay). This runs the same executable many times with different
hand-written tests. I will update the litsupport plugin to utilize the new
functionality (https://reviews.llvm.org/D43316).
These changes allow lit to report micro test results if desired in order to get
many precise timing results from 1 run of 1 test executable.

This has gone back and forth, but it seems this is necessary
after all. realpath is not sufficient because if you have a
file named 'C:\foo.txt', then both realpath('c:\foo.txt') and
realpath(C:\foo.txt') return the string that was passed to them
exactly as is, meaning the case of the drive-letter won't match.
The problem before was not that we were normalizing the case of
items going into the config map, but rather that we were
normalizing the case of something we needed to print. The value
that is used to key on the config map should never be printed.

Config map is not exposed through the command line, so testing this
is somewhat tricky. But basically we need a test that if a custom
driver builds a config map and passes it to main, it gets respected.
A config map allows config files in the source tree to be mapped
to alternate config files in the build tree. This particular test
works by having two config files in separate directories, and
setting up a config map to have that redirects A/lit.site.cfg
to B/altconfig. Then, we print a message in A/lit.site.cfg
and B/altconfig and check that we do see the output from B
but don't see the output from A. Additionally we test that
the test suite specified by A's config map is properly discovered.

llvm-svn: 313335
This patch simplifies LLVM's lit infrastructure by enforcing an ordering
that a site config is always run before a source-tree config.
A significant amount of the complexity from lit config files arises from
the fact that inside of a source-tree config file, we don't yet know if
the site config has been run. However it is *always* required to run
a site config first, because it passes various variables down through
CMake that the main config depends on. As a result, every config
file has to do a bunch of magic to try to reverse-engineer the location
of the site config file if they detect (heuristically) that the site
config file has not yet been run.
This patch solves the problem by emitting a mapping from source tree
config file to binary tree site config file in llvm-lit.py. Then, during
discovery when we find a config file, we check to see if we have a
target mapping for it, and if so we use that instead.
This mechanism is generic enough that it does not affect external users
of lit. They will just not have a config mapping defined, and everything
will work as normal.
On the other hand, for us it allows us to make many simplifications:
* We are guaranteed that a site config will be executed first
* Inside of a main config, we no longer have to assume that attributes
might not be present and use getattr everywhere.
* We no longer have to pass parameters such as --param llvm_site_config=<path>
on the command line.
* It is future-proof, meaning you don't have to edit llvm-lit.in to add
support for new projects.
* All of the duplicated logic of trying various fallback mechanisms of
finding a site config from the main config are now gone.
One potentially noteworthy thing that was required to implement this
change is that whereas the ninja check targets previously used the first
method to spawn lit, they now use the second. In particular, you can no
longer run lit.py against the source tree while specifying the various
`foo_site_config=<path>` parameters. Instead, you need to run
llvm-lit.py.

Summary:
Libc++ frequently has the need to parse more than just the builtin *test keywords* (`RUN`, `REQUIRES`, `XFAIL`, ect). For example libc++ currently needs a new keyword `MODULES-DEFINES: macro list...`. Instead of re-implementing the script parsing in libc++ this patch allows `parseIntegratedTestScript` to take custom parsers.
This patch introduces a new class `IntegratedTestKeywordParser` which implements the logic to parse/process a test keyword. Parsing of various keyword "kinds" are supported out of the box, including 'TAG', 'COMMAND', and 'LIST', which parse keywords such as `END.`, `RUN:` and `XFAIL:` respectively.
As an example after this change libc++ can implement the `MODULES-DEFINES` simply using:
```
mparser = IntegratedTestKeywordParser('MODULES-DEFINES:', ParserKind.LIST)
parseIntegratedTestScript(test, additional_parsers=[mparser])
macro_list = mparser.getValue()

In principle we should run lit's testsuite before testing LLVM using lit
so that any problems with lit get discovered before testing LLVM so we
can bail out early. However this implementation (``check-all`` runs all

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!
