Jordan Rose 111aa9a28b [analyzer] Don't accidentally strip off base object regions for lazy bindings.
If a base object is at a 0 offset, RegionStoreManager may find a lazy
binding for the entire object, then try to attach a FieldRegion or
grandparent CXXBaseObjectRegion on top of that (skipping the intermediate
region). We now preserve as many layers of base object regions necessary
to make the types match.

Arnold Schwaighofer e4df5eb34a ARM NEON: Don't need COPY_TO_REGCLASS in pattern
In my previous commit:
"Merge a f32 bitcast of a v2i32 extractelt

A vectorized sitfp on doubles will get scalarized to a sequence of an
extract_element of <2 x i32>, a bitcast to f32 and a sitofp.
Due to the the extract_element, and the bitcast we will uneccessarily generate
moves between scalar and vector registers."

I added a pattern containing a copy_to_regclass. The copy_to_regclass is
actually not needed.

Edwin Vane 8b526f22c6 Add support for auto-generating LIT tests by the build
autoconf and CMake flavours both updated to auto-generate files for use
in cpp11-migrate's LIT tests.

Auto-generated files are placed in the build directory under
test/cpp11-migrate/autogen. The directory structure past this point
mirrors the structure in the source directory under test/cpp11-migrate.
A lit.site.cfg is generated in test/cpp11-migrate/autogen to describe
the new test suite. When LIT runs, it runs the standard testsuite and
now also the auto-generated testsuite.

Dan Gohman 22954dbb7e Don't trust st_size of a character device. This fixes using
/dev/stdin as an input when stdin is connected to a tty, for example.

No test, because it's difficult to write a reasonably portable test
for this. /dev/stdin isn't a character device when stdin is redirected
from a file or connected to a pipe.

Jakob Stoklund Olesen 7e28db019a Assert that the target provided hints are in the allocation order.
Target implementations of getRegAllocationHints() should use the
provided allocation order, and they can never return hints outside the
order. This is already documented in TargetRegisterInfo.h.

I don't want to rule out the possibility of linking to e.g. interesting

This breaks URL compatibility, but this document was committed less than

Using a new metafunction for detecting the presence of the member
'getDecl' in a type T, added support to hasDeclaration for any such type
T. This allows hasDecl() to be replaced and enables several other
subclasses of clang::Type to use hasDeclaration.

Benjamin Kramer b3aa2b8497 Fix GCMetadaPrinter::finishAssembly not executed, patch by Yiannis Tsiouris.
Due to the execution order of doFinalization functions, the GC information were
deleted before AsmPrinter::doFinalization was executed. Thus, the
GCMetadataPrinter::finishAssembly was never called.

The patch fixes that by moving the code of the GCInfoDeleter::doFinalization to
Printer::doFinalization.

A vectorized sitfp on doubles will get scalarized to a sequence of an
extract_element of <2 x i32>, a bitcast to f32 and a sitofp.
Due to the the extract_element, and the bitcast we will uneccessarily generate

The patch fixes this by using a COPY_TO_REGCLASS and a EXTRACT_SUBREG to extract
the element from the vector instead.

Tom Stellard 8d469edbe3 R600: Fix scheduler crash caused by invalid MachinePointerInfo
Kernel function arguments are lowered to loads from the PARAM_I address
space.  When creating these load instructions, we were initializing
their MachinePointerInfo with an Arguement object that was not attached
to any function.  This was causing the MachineScheduler to crash when
it tried to access the parent of the Arguement.

This has been fixed by initializing the MachinePointerInfo with a
UndefValue instead.

NOTE: This is a candidate for the Mesa stable branch.
