FIXME: It does not improve MSVC's issue.
[Danil Malyshev] Defining PRINTF_EXPONENT_DIGITS env is the suggested way to make MinGW ANSI/POSIX compatible. This is not only about the case we are discussing, but in general, I'd like to have explicitly defined compatibility mode for all the tests running on MinGW.

It seeks tools(eg. [cmp, grep, sed]) in same directory, to be sane.
It seeks "bash" only in the directory found at last time. Or bash would be insane (against other tools).

checkToolsPath(dir,tools):
return True if "dir" contains all "tools".
whichTools(tools,paths):
return a directory that contains all "tools" in "paths".
Or return None when all "tools" were not met.

being tested. This ensures that we test the tools just built and not
some random tools that might happen to be in the user's PATH. This
makes LLVM testing much more stable and predictable.

shell runner.
We would inadvertently end up holding on to handles to the temporary files
longer than we should have been. On Win32, where open handles lock some file
operations, this caused problems in tests which would try to move temporary
files around (as Clang does by default now).
Many thanks to Francois Pichet for the excellent detective work on this.

needs to find some libraries, which may require searching the directories given
by LIBRARY_PATH on curiously configured systems. So pass on LIBRARY_PATH.

it doesn't modify the exit code or the stdout contents, and so that it
doesn't clutter the output with "Command has output on stderr!".

of runs without leak checking. We add -vg to the triple for non-checked runs,
or -vg_leak for checked runs. Also use this to XFAIL the TableGen tests, since
tablegen leaks like a sieve. This includes some valgrindArgs refactoring.

Python 2.4 always hits this bug: http://bugs.python.org/issue1731717
when running check-lit on multi-core systems.
Setting numThreads to 1 makes it slower, but at least the results reported are
correct.

Apparently this happens under certain versions of glibc, so valgrind provides
the --run-libc-freeres=no option to avoid calling freeres(). This may increase
the number of "still reachable" blocks valgrind reports, but we don't care
about those, while this error breaks the buildbots.
There are upstream bugs about this at
http://sourceware.org/bugzilla/show_bug.cgi?id=10610 and
http://bugs.kde.org/show_bug.cgi?id=167483, but they don't look likely to be
fixed.

IF(condition(value)):
If the value satisfies the condition, the line is processed by lit; otherwise
it is skipped. A test with no unignored directives is resolved as Unsupported.
The test suite is responsible for defining conditions; conditions are unary
functions over strings. I've defined two conditions in the LLVM test suite,
TARGET (with values like those in TARGETS_TO_BUILD) and BINDING (with values
like those in llvm_bindings). So for example you can write:
IF(BINDING(ocaml)): RUN: %blah %s -o -
and the RUN line will only execute if LLVM was configured with the ocaml
bindings.
