Because the delinearization is not a global analysis pass, it will compute the
delinearization independently of knowledge about the way the delinearization
happened for other data accesses to the same array: the dependence analysis will
only trigger the delinearization on a tuple of access functions, and thus
delinearization may compute different subscripts sizes for a same array. When
that happens the safest is to discard the delinearized information.

We now skip the debug intrinsics which is a lot better than crashing due to
uncopied metadata references. We should step by step investigate which debug
intrinsics we can copy without trouble.
We still keep the debug location metadata.

llvm_add_library(foo SHARED STATIC
DEPENDS <dependent targets...>
LINK_LIBS <required libraries...>
)
It generates both foo (foo.so) and foo_static(foo.a) and both of them depend on DEPENDS and LINK_LIBS.
Then, also obj.foo is generated. obj.foo depends on DEPENDS, but doesn't depend on LINK_LIBS.

The module still needs to collect the list of all available libraries
in order to satisfy the 'all' component. Provide this in the package
configuration file, 'LLVMConfig.cmake', as a LLVM_AVAILABLE_LIBS
variable. (A variable is scoped better than a global property.)
Since this won't be set for our own build, fall back to looking up the
LLVM_LIBS property to get the value when it is not set.

LLVM library names are now available as logical CMake targets both
to our own build and to application CMake code. Replace use of
'list(FIND)' with a simple 'if(TARGET)' to determine whether a
library is available.

This extends the intrinsic lookup table format slightly, and adds
entries for use the shared ARM/AArch64 definitions. The benefit is
currently smaller than for the SISD intrinsics (there's more custom
code implementing this set), but a few lines are saved and there's
scope for future expansion.
llvm-svn: 201848
This extracts the table-driven intrinsic lookup phase into a separate
function, to be used by EmitCommonNeonBuiltinExpr soon.
It also simplifies the logic used in that lookup, since VectorCastArgN
and ScalarArgN were actually identical.

Added two new options for -mfpu when targetting ARM:
* fpv4-sp-d16
* fp4-sp-d16
The first is the same spelling as gcc.
The lack of a leading `v' is correct, this is consistent with ARM's
documentation and gcc's spelling of the option.

When actually compiling we use clang for the final .dylib creation stage, so we
should ask it what linker it'll use when detecting support for our
architectures.

Error 1 error C2681: 'add_rvalue_reference<_Tp*>::type' : invalid expression
type for dynamic_cast c:\libcxx\include\type_traits
This is one more step getting libcxx compile under Visual C++. The patch is
#if defined(_LIBCPP_MSVC) so will affect only this build.
When libcxx can be compiled, it will probably require the current version or
maybe even the next Update of Visual C++ 2013.

them to be.

This does;
- clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list.
- List of targets is added to LLVM_COMMON_DEPENDS.
- all clang libraries and targets depend on generated headers.
You might wonder this would be regression, but in fact, this is little loss.
- Almost all of clang libraries depend on tblgen'd files and clang-tblgen.
- clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild.
- Each library's dependencies to tblgen'd files might vary along headers' structure.
It made hard to track and update *really optimal* dependencies.
Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS.

class. If we try to unwind a stack frame to find a caller stack
frame, and we fail to get a valid-looking frame, AND if the UnwindPlan
we used is an assembly-inspection based UnwindPlan, then we should
throw away the assembly-inspection UnwindPlan and try unwinding with
the architectural default UnwindPlan.
This code path won't be taken if eh_frame unwind instructions are available -
lldb will always prefer those once it's off the zeroth frame.
The problem I'm trying to fix here is the class of unwind failures that
happen when we have hand-written assembly on the stack, with no eh_frame,
and lldb's assembly parser fails to understand the assembly. People usually
write their hand-written assembly to follow the frame-pointer-preserving
conventions of the platform so the architectural default UnwindPlan will
often work. We won't have the spill location for most of the non-volatile
registers if we fall back to this, but it's better than stopping the unwind
prematurely.
This is a bit of a tricky change that I believe is correct, but if we get
unwinds that go of into the weeds / unwind bogus frames at the end of the
stack, I'll need to revisit it.

This replaces the old NoIntegratedAssembler with at TargetOption. This is
more flexible and will be used to forward clang's -no-integrated-as option.

Virtual methods expect 'this' to point to the vfptr containing the
virtual method, and this extends to virtual member pointer thunks. The
relevant vfptr is always at offset zero on entry to the thunk, and no
this adjustment is needed.
Previously we would not include the vfptr adjustment in the member
pointer, and we'd look at the vfptr offset when loading from the vftable
in the thunk.
Fixes PR18917.

Slight change to the way zero-sized sub-objects are tracked in the

In addition we correctly distinguish between dsize and nvsize.

There is no bound architecture for the dsymutil action in the driver. Trying

because the target doesn't get initialized without a bound architecture.

I am really sorry for the noise, but the current state where some parts of the
code use TD (from the old name: TargetData) and other parts use DL makes it
hard to write a patch that changes where those variables come from and how
they are passed along.

should not be marked nounwind.
Marking them nounwind caused crashes in the WebKit FTL JIT, because if we enable
sufficient optimizations, LLVM starts eliding compact_unwind sections (or any unwind
data for that matter), making deoptimization via stackmaps impossible.
This changes the stackmap intrinsic to be may-throw, adds a test for exactly the
sympton that WebKit saw, and fixes TableGen to handle un-attributed intrinsics.
Thanks to atrick and philipreames for reviewing this.

The pp-trace clang tool was using it successfully. We can still delete
the callbacks in Frontend/PrintPreprocessedOutput.cpp because they were

The MS ABI requires that we determine the vbptr offset if have a

gcc never expands macros in pragmas and MSVC always expands macros
before processing pragmas. Clang usually allows macro expansion, except
in a handful of pragmas, most of which are handled by the lexer.
Also remove PPCallbacks for pragmas that are currently handled in the
parser. Without a Parser, such as with clang -E, these callbacks would
never be called.
Fixes PR18576.

This reduces the number of files we need to touch to add a new pragma,
and reduces the number of externally visible symbols in clang.
Make the handlers structs instead of classes because the vast majority
have no private members.

The SuppressWarnings flag, unfortunately, isn't very useful for custom tools
that want to use the LLVM module linker. So I'm changing it to a parameter of
the Linker, and the flag itself moves to the llvm-link tool.
For the time being as SuppressWarnings is pretty much the only "option" it
seems reasonable to propagate it to Linker objects. If we end up with more
options in the future, some sort of "struct collecting options" may be a
better idea.

Previously reverted in r201755 due to causing an assertion failure.
I've removed the offending assertion, and taught the CompilerInstance to
create a default virtual file system inside createFileManager. In the
future, we should be able to reach into the CompilerInvocation to
customize this behaviour without breaking clients that don't care.

This pass eliminates loop iterations that compute results that are not used
later on. This can help e.g. in D, where the default zero-initialization is
often unnecessary if right after new values are assigned to an array.
