Also always add DIType, DISubprogram and DIGlobalVariable to the list
in DebugInfoFinder without checking them, so we can verify them later
on.

Adds unit tests for it too.

Split BasicBlockUtils into an analysis-half and a transforms-half, and put the
analysis bits into a new Analysis/CFG.{h,cpp}. Promote isPotentiallyReachable
into llvm::isPotentiallyReachable and move it into Analysis/CFG.

Some sections, such as with IMAGE_SCN_LNK_REMOVE attribute, is skipped
in the first pass. Such sections need to be skipped in the latter passes.

This establishes a new Flag in Options.td, which can be assigned to
options that should be made available in clang's cl.exe compatible
mode, and updates the Driver to make use of the flag.

(The whitespace change to CMakeLists forces the build to re-run CMake
 and pick up the include dependency on the new .td file. This makes the
 build work if someone moves backwards in commit history after this change.)

Merge consecutive if-regions if they contain identical statements.
Both transformations reduce number of branches.  The transformation
is guarded by a target-hook, and is currently enabled only for +R600,
but the correctness has been tested on X86 target using a variety of
CPU benchmarks.

Fixed case change that caused the test failure.  Incorporarated Sean's review changes, consisting only of renaming and comment changes.

This matches how we normally perform semantic analysis for other sorts
of invalid expressions: it means we don't have to reason about invalid
sub-expressions.

Fixes PR16680.

no return type is specified, C++11 will deduce a cv-qualified return type in
some cases, but C++1y never will.

SLP Vectorier:  Don't vectorize really short chains because they are already handled by the SelectionDAG store-vectorizer, which does a better job in deciding when to vectorize.

PR16708: If a lambda has an implicit return type, don't get confused if its return type has already been determined to be a type containing an 'auto'.

SLP Vectorizer: Disable the vectorization of non power of two chains, such as <3 x float>, because we dont have a good cost model for these types.

Patch by Ron Ofir.

llvm-svn: 187262

This change makes test with RUN lines like
RUN: opt ... | FileCheck

fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.

Pipefail is used when the shell supports it or when using the internal
python based tester.

Missing files will be reported as errors in the later pass, so this patch
does not change the behavior of the LLD linker, but it helps writing unit
tests for the driver.

also worthwhile for it to look through FP extensions and truncations, whose

Both GCC and LLVM will implicitly define __ppc__ and __powerpc__ for
all PowerPC targets, whether 32- or 64-bit.  They will both implicitly
define __ppc64__ and __powerpc64__ for 64-bit PowerPC targets, and not
for 32-bit targets.  We cannot be sure that all other possible
compilers used to compile Clang/LLVM define both __ppc__ and
__powerpc__, for example, so it is best to check for both when relying
on either inside the Clang/LLVM code base.

This patch makes sure we always check for both variants.  In addition,
it fixes one unnecessary check in lib/Target/PowerPC/PPCJITInfo.cpp.
(At least one of __ppc__ and __powerpc__ should always be defined when
compiling for a PowerPC target, no matter which compiler is used, so
testing for them is unnecessary.)

There are some places in the compiler that check for other variants,
like __POWERPC__ and _POWER, and I have left those in place.  There is
no need to add them elsewhere.  This seems to be in Apple-specific
code, and I won't take a chance on breaking it.

There is no intended change in behavior; thus, no test cases are
added.

When BUILD_CLANG_ONLY is set to YES, it is supposed to simply limit the tools
that get built.  The change in r184794 broke this feature by moving libclang
and c-index-test into PARALLEL_DIRS. Those are both supposed to be in DIRS,
because c-index-test has a build dependency on libclang and cannot be
reliably built in parallel with it.
