Zachary Turner 215eafd2d9 [lit] Actually do normalize the case of files in the config map.
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.

Zachary Turner 2462b0299b [lit] Add a test for the builtin config map.
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.

Zachary Turner 1e4a125226 [lit] Make lit support config files with .py extension.
Many editors and Python-related diagnostics tools such as
debuggers break or fail in mysterious ways when python files
don't end in .py.  This is especially true on Windows, but
still exists on other platforms.  I don't want to be too heavy
handed in changing everything across the board, but I do want
to at least *allow* lit configs to have .py extensions.  This
patch makes the discovery process first look for a config file
with a .py extension, and if one is not found, then looks for
a config file using the old method.  So for existing users, there
should be no functional change.

Zachary Turner a0f1ea32df Resubmit "[lit] Force site configs to run before source-tree configs"
This is a resubmission of r313270.  It broke standalone builds of
compiler-rt because we were not correctly generating the llvm-lit
script in the standalone build directory.

The fixes incorporated here attempt to find llvm/utils/llvm-lit
from the source tree returned by llvm-config.  If present, it
will generate llvm-lit into the output directory.  Regardless,
the user can specify -DLLVM_EXTERNAL_LIT to point to a specific
lit.py on their file system.  This supports the use case of
someone installing lit via a package manager.  If it cannot find
a source tree, and -DLLVM_EXTERNAL_LIT is either unspecified or
invalid, then we print a warning that tests will not be able
to run.

Zachary Turner 837d04db84 [lit] Force site configs to be run before source-tree configs
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.

Victor Leschuk d177228190 Make lit :: shtest-format.py supported on Windows again
It was marked as unsupported on Windows in r311230 because on some Win10 
machines it failed or caused hang. The problem was that on these machines
system bash (C:\Windows\System32\bash.exe) was used which requires paths to be
passed like '/mnt/c/path/to/my/script' instead of 'C:\path\to\my\script'.

TODO: we should make lit detect if system bash is used instead of msys and set
appropriate path format.

Greg Bedwell 123eabac1f Fix check-lit compatibility with multi-config CMake generators
Multi-configuration CMake generators such as those for Visual Studio or Xcode do not
specify a build config at configure time, but let the user choose at build
time.  In these cases binaries go into build/${Configuration}/bin rather than
build/bin.  Prior to this commit, check-lit would fail when using multi-configuration
generators as it did not know how to resolve ${Configuration} in order
to find tools such as FileCheck.  This commit teaches it to resolve
llvm_tools_dir within lit using the value specified with --param
build_mode.

Reid Kleckner c39935fb15 [lit] Avoid copying llvm/utils/lit/tests/Inputs with lit site configs
Summary:
This is an alternative solution to running the lit test suite on bots
without polluting the source directory. Each input test suite gets an
auto-generated site config in the build directory that points back to
the test input source directory.

This adds some cmake comlexity, but now we don't need to remove and
re-copy the test input directory before every test.

Summary:
The technique of directly calling subprocess.Popen on a python script
doesn't work on Windows. The executable path of the command must refer
to a valid win32 executable.

Instead, rename all the python scripts masquerading as gtest executables
to have .py extensions, so we can easily detect then and call the python
executable for them. Do this on Linux as well as Windows for
consistency.

The test suite directory names also come out in lower-case on Windows.
We can consider removing that in a later patch. This change just updates
the FileCheck lines to match on Windows.

Brian Gesiak 8f6b2b6630 [lit] Mark several of lit's tests XFAIL on Windows
Summary:
rL257221 attempted to run lit's own test suite continuously, but that
commit was reverted because lit's test suite does not pass on Windows.
Because lit's tests do not run continuously, they often regress.

In order to un-revert rL257221, mark lit tests that fail as XFAIL for
Windows platforms.

Test Plan:
On a Windows development environment, follow the instructions in
utils/lit/README.txt to run lit's test suite:

```
utils/lit/lit.py \
    --path /path/to/your/llvm/build/bin \
    utils/lit/tests
```

Verify that the test suite is run and a successful exit code is
returned.

George Karpenkov 80c7e63a6d [lit] Modify LIT to accept environment variable LIT_FILTER to select tests.
This is especially useful when lit is invoked indirectly by the build
system, and additional arguments can not be easily specified.

Reid Kleckner 57cceedbb1 [lit] Implement timeouts and max_time for process pool testing
This is necessary to pass the lit test suite at llvm/utils/lit/tests.

There are some pre-existing failures here, but now switching to pools
doesn't regress any tests.

I had to change test-data/lit.cfg to import DummyConfig from a module to
fix pickling problems, but I think it'll be OK if we require test
formats to be written in real .py modules outside lit.cfg files.

I also discovered that in some circumstances AsyncResult.wait() will not
raise KeyboardInterrupt in a timely manner, but you can pass a non-zero
timeout to work around this. This makes threading.Condition.wait use a
polling loop that runs through the interpreter, so it's capable of
asynchronously raising KeyboardInterrupt.

Brian Gesiak 81e6d00cf5 lit: remove python2-isms
Summary:
`assert.assertItemEqual` went away in Python 3. Seeing how lists
are ordered, comparing a list against each other should work just
as well.

Patch by @jbergstroem (Johan Bergström).

Greg Parker 7664071405 [lit] Allow boolean expressions in REQUIRES and XFAIL and UNSUPPORTED
A `lit` condition line is now a comma-separated list of boolean expressions. 
Comma-separated expressions act as if each expression were on its own 
condition line:
For REQUIRES, if every expression is true then the test will run. 
For UNSUPPORTED, if every expression is false then the test will run. 
For XFAIL, if every expression is false then the test is expected to succeed. 
As a special case "XFAIL: *" expects the test to fail.

Examples:
# Test is expected fail on 64-bit Apple simulators and pass everywhere else
XFAIL: x86_64 && apple && !macosx
# Test is unsupported on Windows and on non-Ubuntu Linux 
# and supported everywhere else
UNSUPPORTED: linux && !ubuntu, system-windows

Syntax: 
* '&&', '||', '!', '(', ')'. 'true' is true. 'false' is false.
* Each test feature is a true identifier. 
* Substrings of the target triple are true identifiers for UNSUPPORTED 
 and XFAIL, but not for REQUIRES. (This matches the current behavior.)
* All other identifiers are false.
* Identifiers are [-+=._a-zA-Z0-9]+

Graydon Hoare 57f557b15d [lit] Support sharding testsuites, for parallel execution.
Summary:
This change equips lit.py with two new options, --num-shards=M and
--run-shard=N (set by default from env vars LIT_NUM_SHARDS and LIT_RUN_SHARD).

The options must be used together, and N must be in 1..M.

Together these options effect only test selection: they partition the testsuite
into M equal-sized "shards", then select only the Nth shard. They can be used
in a cluster of test machines to achieve a very crude (static) form of
parallelism, with minimal configuration work.
