Volatile bitfields can cause valid stores of uninitialized bits.

llvm-svn: 173153

A runtime call is used instead.
MSan will stop adding shadow checks on volatile stores soon.

This is a follow-up to r171845, which fixes the same issue in the Support code.
Only targets with >256 relocations (principally AArch64) should be affected.

Before: A = new int * [10]();
After:  A = new int *[10]();

generic function calls and intrinsics. This is somewhat overlapping with
an existing intrinsic cost method, but that one seems targetted at
vector intrinsics. I'll merge them or separate their names and use cases
in a separate commit.

This sinks the test of 'callIsSmall' down into TTI where targets can
control it. The whole thing feels very hack-ish to me though. I've left
a FIXME comment about the fundamental design problem this presents. It
isn't yet clear to me what the users of this function *really* care
about. I'll have to do more analysis to figure that out. Putting this
here at least provides it access to proper analysis pass tools and other
such. It also allows us to more cleanly implement the baseline cost
interfaces in TTI.

With this commit, it is now theoretically possible to simplify much of
the inline cost analysis's handling of calls by calling through to this
interface. That conversion will have to happen in subsequent commits as
it requires more extensive restructuring of the inline cost analysis.

The CodeMetrics class is now really only in the business of running over
a block of code and aggregating the metrics on that block of code, with
the actual cost evaluation done entirely in terms of TTI.

[ASan] Remove the declarations of pthread_workqueue_t and pthread_workitem_handle_t, which are used no more.

This change also makes the serialisation store the required semantics,
fixing an issue where PPC128 was always assumed when re-reading a
128-bit value.

llvm-svn: 173139

Previously we tried to infer it from the bit width size, with an added
IsIEEE argument for the PPC/IEEE 128-bit case, which had a default
value. This default value allowed bugs to creep in, where it was
inappropriate.

We already have Darwin-specific version of this test.

This patch changes the behavior of the -fsanitize=address flag, making it use the dynamic runtime library (libclang_rt.asan_osx_dynamic.dylib) instead of the static one. It also drops the CoreFoundation dependency, since the dynamic runtime doesn't need it.

llvm-svn: 173135

This CL drastically simplifies the way we're hooking the memory allocation routines in ASan on Mac by using dylib interposition to replace the main malloc_zone_* functions. This allows us to avoid replacing the default CFAllocator and drop the CF dependency at all.

Committing this patch will result in the static runtime being broken. A follow-up CL will switch ASan to use the dynamic runtime library.

only contain -objc-arc-aa, not the full -objc-arc.

it looks like g++ 4.7.2 doesnot like bit fields when the type is a enumeration (Throws an error as bit-field with non integral type)

We were previously hard-coding a particular field index.  This was
fine before (because we were obviously guaranteed the presence
of a copy/dispose member) except for (1) alignment padding and
(2) future extensions adding extra members to the header, such
as the extended-layout pointer.

Note that we only introduce the extended-layout pointer in the
presence of structs.  (We also seem to be introducing it even
in the presence of an all-non-object layout, but that's a
different potential issue.)
