I totally forgot that char can be defined as unsigned on some platforms.
Now I made explicit mention of signed type where necessary in tests.
Also fixed '//RUN: ' header of cxx98 test to correct format.

I am also letting a debugserver-related project entry slide in
since Xcode seems to insist on inserting it, and when I remove it
the new files don't show up.

When the target does not support these intrinsics they should be converted to a chain of scalar load or store operations.
If the mask is not constant, the scalarizer will build a chain of conditional basic blocks.
I added isLegalMaskedGather() isLegalMaskedScatter() APIs.

Summary:
This is another check that I ported to clang-tidy from colobot-lint tool.
As previously discussed on cfe-dev mailing list, this is one of those
checks that I think is general and useful enough for contribution to
clang-tidy.
This patch contains implementation of check taken from colobot-lint, but
it is extended a great deal, including FixIt hints for automated
refactoring, exhaustive testcases, and user documentation.

Volatile or atomic memory accesses are currently not supported. Neither did
we think about any special handling needed nor do we support the unknown
instructions the alias set tracker turns them into sometimes. Before this
patch, us not supporting unkown instructions in an alias set caused the
following assertion failures:
Assertion `AG.size() > 1 && "Alias groups should contain at least two accesses"'
failed

When verifying if a scop is still valid we rerun all analysis, but did not
update DetectionContextMap. This change ensures that information, e.g. about
non-affine regions, is correctly updated

the size expression.
We previously only checked if the size expression is 'undef', but allowed size
expressions of the form 'undef * undef' by accident. After this change we now
require size expressions to be affine which implies no 'undef' appears anywhere
in the expression.

The MCU psABI calling convention is somewhat, but not quite, like -mregparm 3.
In particular, the rules involving structs are different.

When using the MCU psABI, compiler-generated library calls should pass
some parameters in-register. However, since inreg marking for x86 is currently
done by the front end, it will not be applied to backend-generated calls.
This is a workaround for PR3997, which describes a similar issue for -mregparm.

This adds support for the i?86-*-elfiamcu triple, which indicates the IAMCU psABI is used.

Update ccc-analyzer to forward both -Xclang and its following argument to the
the compiler driver. Previously we were dropping -Xclang and forwarding the
argument on its own if it matched other forwarding criteria. This caused the
argument to be interpreted as a driver rather than a frontend option.

I think it's fine to keep this fields around in terms of overhead,
I wasn't able to measure any substantial regression while running the
test suite, but, in case this causes some regression I'm ready to revert
and work on an alternative solution.
This was tested building with clang/gcc both in Debug and Release mode
and passes the test-suite.

of the Region are external.
During code generation we split off the parts of the PHI nodes in the entry
block, which have incoming blocks that are not part of the region. As these
split-off PHI nodes then are external uses, we consequently also need to model
these uses in ScopInfo.

This list is produced by llvm-config --system-libs to be used
by external programs using the llvm libraries, such as creduce.
In r250501 llvm/Support/Windows/Path.inc started to use the constant
FOLDERID_Profile from libuuid.
