When running the tests under Cygwin using non-Cygwin python,
the platform would be Windows and there would be bash on the path,
so this check for MSYS would not work correctly.

The mode doesn't actually do anything yet, but this provides a
way to get into it.

and add a new option --driver-mode= to control it explicitly.

The CCCIsCXX and CCCIsCPP flags were non-overlapping, i.e. there
are currently really three modes that Clang can run in: gcc, g++
or cpp, so it makes sense to represent them as an enum.

Having a command line flag to control it helps testing.

[clang-lit] Added the run_long_tests param option/long_tests feature to toggle execution of long running FileCheck tests.

This will allow for longer running FileCheck based tests to be committed to
clang for use on buildbots, preventing the normal make-check cycle from
increasing in time significantly.

This is a necessary change in order to commit the end-to-end arm neon intrinsic
tests since FileCheck takes ~20 seconds to run said test due to the large amount
of neon intrinsics.

To force a test to run only when --param run_long_tests=true is passed in use
the following requires statement:

// REQUIRES: long_tests

TLS support.

llvm-svn: 179692

We currently emit an error message when you try to use thread local
storage on targets that don't support it and testing C++11 thread
locals will trip this. We don't want to xfail the test for all darwin
hosts so add a quick hack to check for darwin10 and disable the
test based on that. Only checking darwin10 because anything earlier
is really old and I don't have a list of what other hosts don't
support tls handy.

Alternate suggestions welcome!

The behavior can be overridden by setting LIT_USE_INTERNAL_SHELL=0 in

The stat cache became essentially useless ever since we started
validating all file entries in the PCH.
But the motivating reason for removing it now is that it also affected
correctness in this situation:

-You have a header without include guards (using "#pragma once" or #import)
-When creating the PCH:
  -The same header is referenced in an #include with different filename cases.
  -In the PCH, of course, we record only one file entry for the header file
  -But we cache in the PCH file the stat info for both filename cases

-Then the source files are updated and the header file is updated in a way that
 its size and modification time are the same but its inode changes

-When using the PCH:
  -We validate the headers, we check that header file and we create a file entry with its current inode
  -There's another #include with a filename with different case than the previously created file entry
  -In order to get its stat info we go through the cached stat info of the PCH and we receive the old inode
  -because of the different inodes, we think they are different files so we go ahead and include its contents.

Removing the stat cache will potentially break clients that are attempting to use the stat cache
as a way of avoiding having the actual input files available. If that use case is important, patches are welcome
to bring it back in a way that will actually work correctly (i.e., emit a PCH that is self-contained, coping with
literal strings, line/column computations, etc.).

The implementation also includes a Relax NG schema and tests for the schema
itself.  The schema is used in c-index-test to verify that XML documents we
produce are valid.  In order to do the validation, we add an optional libxml2
dependency for c-index-test.
