OpenMP 4.5 adds directives 'taskloop' and 'taskloop simd'. These directives support clause 'num_tasks'. Patch adds parsing/semantic analysis for this clause.
llvm-svn: 255008
Summary:
Adds new option -fthinlto-index=<file> to invoke the LTO pipeline
along with function importing via clang using the supplied function
summary index file. This supports invoking the parallel ThinLTO
backend processes in a distributed build environment via clang.
Additionally, this causes the module linker to be invoked on the bitcode
file being compiled to perform any necessary promotion and renaming of
locals that are exported via the function summary index file.
Add a couple tests that confirm we get expected errors when we try to
use the new option on a file that isn't bitcode, or specify an invalid
index file. The tests also confirm that we trigger the expected function
import pass.

Constructors and destructors may be represented by several functions
in IR. Only base structors correspond to source code, others are
small pieces of code and eventually call the base variant. In this
case instrumentation of non-base structors has little sense, this
fix remove it. Now profile data of a declaration corresponds to
exactly one function in IR, it agrees with the current logic of the
profile data loading.
This change fixes PR24996.

From the description, I suspect that the wrong patch was committed here,

After r251874, properties from class extensions no longer show up in
ObjCInterfaceDecl::properties(). Make debug info emission explicitly
look for properties in class extensions before looking at direct properties.
Also add a test that checks for this. There are three interesting cases:
1. A property is only declared in a class extension, and the @implementation
is in a different file. This used to generated a DIObjcProperty before
r251874 and does again with this fix.
2. A property is declared as readonly in the class itself and redeclared as
readwrite in a class extension. clang before r251874 put the DIObjcProperty
on the first declaration. clang after r251874 didn't emit any DIObjcProperty,
and clang with this fix puts it on the readwrite redeclaration (which is
what lookup finds). This seems like a progression.
3. Like 2, but with an @implementation in the same file. In this case,
the property debug info gets generated a second time through the ivar
from the definition. In this case, lookup and declaration code need
to agree on the line number so that the DIObjcProperty isn't emitted
twice. In this case, clang before r251874 emitted one DIObjcProperty
on the first declaration, clang with r251874 emitted one on the second
declaration, and clang with this patch still does the latter.

Summary:
Looking into some recent issues with LLDBs expression parser highlighted that upstream clang passes vectors types differently to Android Open Source Project's clang for Arm Android targets.
This patch reflects the changes present in the AOSP and allows LLDB's JIT expression evaluation to work correctly for Arm Android targets when passing vectors.

llvm-svn: 254554
Summary:
This patch implements the 4.5 specification for the implicit data maps. OpenMP 4.5 specification changes the default way data is captured into a target region. All the non-aggregate kinds are passed by value by default. This required activating the capturing by value during SEMA for the target region. All the non-aggregate values that can be encoded in the size of a pointer are properly casted and forwarded to the runtime library. On top of fixing the previous weird behavior for mapping pointers in nested data regions (an explicit map was always required), this also improves performance as the number of allocations/transactions to the device per non-aggregate map are reduced from two to only one - instead of passing a reference and the value, only the value passed.
Explicit maps will be added later on once firstprivate, private, and map clauses' SEMA and parsing are available.

This patch changes the generation of CGFunctionInfo to contain
the FunctionProtoType if it is available. This enables the code
generation for call instructions to look into this type for
exception information and therefore generate better quality
IR - it will not create invoke instructions for functions that
are know not to throw.

The pointer returned by __RTDynamicCast must be bitcasted. However, it
was not expected that __RTDynamicCast would be invoked, resulting in the
bitcast occuring in a different BasicBlock than the invoke. This caused
a down-stream PHI to get confused about which BasicBlock the incomming
value was from.
This fixes PR25606.

driving a canonical difference between that and an unqualified
type is a really bad idea when both are valid. Instead, remember
that it was there in a non-canonical way, then look for that in
the one place we really care about it: block captures. The net
effect closely resembles the behavior of a decl attribute, except
still closely following ARC's standard qualifier parsing rules.

These intrinsics currently have an explicit alignment argument which is
required to be a constant integer. It represents the alignment of the
source and dest, and so must be the minimum of those.
This change allows source and dest to each have their own alignments
by using the alignment attribute on their arguments. The alignment
argument itself is removed.
The only code change to clang is hidden in CGBuilder.h which now passes
both dest and source alignment to IRBuilder, instead of taking the minimum of
dest and source alignments.
