559074a285 Teach Lit to catch OSError exceptions when creating a process during the
execution of a shell command. This can happen for example if the
``RUN:`` line calls a python script which can work correctly under
Linux/OSX but will not work under Windows. A more useful error message
is now shown rather than an unhelpful backtrace.

c919e57cbf [lit] Parse all strings as UTF-8 rather than ASCII.
As far as I can tell UTF-8 has been supported since the beginning of Python's
codec support, and it's the de facto standard for text these days, at least
for primarily-English text. This allows us to put Unicode into lit RUN lines.

e1167f1319 [LIT] Move display of unsupported and xfail tests to summary.
Summary:
This patch changes the way xfail and unsupported tests are displayed. 
This output is only displayed when the --show-unsupported/--show-xfail flags are passed to lit.

Currently xfail/unsupported tests are printed during the run of the test-suite. I think its better to display this information during the summary instead.
This patch removes the printing of these tests from when they are run to the summary.

2785e77db1 [lit] Add --show-xfail flag to LIT.
Summary:
This patch add a --show-xfail flag. If this flag is specified then each xfail test will be printed to output.
When it is not given xfail tests are ignored. Ignoring xfail tests is the current behavior.

This flag is meant to mirror the --show-unsupported flag that was recently added.

It would previously say things like

and have the user pull their hair trying to figure out what's wrong with that
file. This patch changes the message to the much clearer:

  warning: no such file or directory: 'test/Frontend/foo.c'

22471f5731 Add detection of OS X relocatable SDK to compiler-rt as a lit.util function
Clang's lit cfg already detects the currently selected SDK via
"xcrun --show-sdk-path". The same thing should be done for compiler-rt tests,
to make them work on recent OS X versions. Instead of duplicating the detection
code, this patch extracts the detection function into a lit.util method.

4c28d2024f lit: execfile() isn't present in Python 3.3
On the other hand, exec(compile()) doesn't work in older Python versions in the
2.x series.

This commit introduces exec(compile()) with a fallback to plain exec(). That'll
hopefully hit the sweet spot in terms of version support.

Followup to r198766 which added enhanced source locations for lit cfg parsing.

598887906b lit: Provide file location in cfg error messages
Python doesn't do a good job at diagnosing string exec() so use execfile()
where available.

This should be a timesaver when trying to get to the bottom of build bot
failures.

Before:

    File "llvm/utils/lit/lit/TestingConfig.py", line 93, in load_from_path
      exec("exec data in cfg_globals")
    File "<string>", line 1, in <module>
    File "<string>", line 194, in <module>
  NameError: name 'typo' is not defined

After:

    File "llvm/utils/lit/lit/TestingConfig.py", line 95, in load_from_path
    execfile(path, cfg_globals)
    File "clang/test/lit.cfg", line 194, in <module>
      typo

9ad6e339c3 lit: Incremental test scheduling
Add option -i to prioritize test runs by source file modification time and
previous failure state.

This optimal scheduling reduces typical test-and-fix iteration times to a
matter of seconds by rapidly answering the questions:

  1) Did my recent change fix tests that were previously failing?
  2) Do the tests I just wrote / modified still work?

The current implementation requires write permissions to the source tree
because it uses mtimes to track failures.
