Alp Toker 120dd1afaf Add tests for clang plugins
Somehow the entire plugin infrastructure went wholly untested until now.

The only plugins available for use in testing are the examples, so plugin tests
will only be run if CLANG_BUILD_EXAMPLES is enabled in the build.

(The examples should really be enabled by default, not just to aid testing but
also to prevent bitrot in some key user-facing code. I'll propose that
shortly.)

Requires supporting changes in LLVM r198746.

NAKAMURA Takumi 67eade63fd check-clang: Introduce get_llvm_config_props in clang/test/lit.cfg.
In trunk, we can use features as below:

  aarch64-registered-target
  hexagon-registered-target
  msp430-registered-target
  r600-registered-target
  systemz-registered-target
  xcore-registered-target

Each of them, as below, implies corresponding subtargets:

  arm-registered-target   -- arm, thumb
  mips-registered-target  -- mips, mips64, mips64el, mipsel
  nvptx-registered-target -- nvptx, nvptx64
  sparc-registered-target -- sparc, sparcv9
  x86-registered-target   -- x86, x86-64

They will be renamed:

  cppbackend-registered-target -- was "cpp". Unused in trunk.
  powerpc-registered-target -- was "ppc32", "ppc64" and "ppc64le".

The feature "asserts" is also taken from llvm-config.

Alp Toker 9c5ae47c94 Ignore test Inputs globally and remove redundant lit.local.cfg files
By adding a default config.excludes pattern we can avoid individual
suppressions in subdirectories.

This matches LLVM's lit.cfg which also excludes a few other common non-test
filenames for consistency.

Hans Wennborg dffe59932b lit.cfg: better check for MSYS
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.

Hans Wennborg e4b031ca03 Add a cl.exe compatible driver mode
The mode doesn't actually do anything yet, but this provides a

2013-07-19 20:33:20 +00:00
Hans Wennborg 70850d83dc Turn Driver::CCCIsCXX and CCCIsCPP into a single Mode enum,
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.

Michael Gottesman 6ef6e142c7 [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

Eric Christopher 6ddf14db89 Add a bit of a hack to deal with a failing testcase on darwin10 bots.
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!

Argyrios Kyrtzidis d7c16b2543 [PCH] Remove the stat cache from the PCH file.
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.).

Dmitri Gribenko 740c0fbe0e libclang API for comment-to-xml conversion.
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.

Chandler Carruth a62ba81682 Rip out one of the features I added for the driver-include-management.
We don't actually need a separate flag for non-sysrooted paths as the
driver has to manage the sysroot anyways. The driver is not infrequently
adding paths to the header search based on their existence on the
filesystem. For that, it has to add the sysroot anyways, we should pass
it on down to CC1 already joined. More importantly, the driver cannot in
all cases distinguish between sysrooted paths and paths that are
relative to the Clang binary's installation directory. Essentially, we
always need to ignore the system root for these internal header search
options. It turns out in most of the places we were already providing
the system root in the driver, and then another one in CC1 so this fixes
several bugs.
