Enrico Granata 0aa6926d0b When parsing ObjC types from encoded strings (and disallowing any-type), the ^? combination gets resolved to no type, while we could resolve it to void*
I don't think on any of the platforms where ObjC matters sizeof(T*) depends on T, so even if we never figured out the pointee type, the pointer type should still be sane
This might also allow some limited inspection where previously none was possible, so a win

Justin Bogner a8dd73229e Correctly handle reading locations from serialized diagnostics
When reading a serialized diagnostic location with no file ID, we were
failing to increment the cursor past the rest of the location. This
would lead to the flags and category always appearing blank in such
diagnostics.

This changes the function to unconditionally increment the cursor and
updates the test to check for the correct output instead of testing
that we were doing this wrong. I've also updated the error check to
check for the correct number of fields.

Alexey Samsonov 8a584bb3d7 Re-land r219354: Use llvm-symbolizer to symbolize LLVM/Clang crash dumps.
In fact, symbolization is now expected to work only on Linux and
FreeBSD/NetBSD, where we have dl_iterate_phdr and can learn the
main executable name without argv0 (it will be possible on BSD systems
after http://reviews.llvm.org/D5693 lands). #ifdef-out the code for
all the rest Unix systems.

Bob Wilson 771b7cd812 Remove a FIXME: use the ios_simulator_version_min linker option consistently.
This was previously only used when explicitly requested with a command line
option because it had to work with some old versions of the linker when it
was first introduced. That is ancient history now, and it should be safe to
use the correct option even when using the IPHONEOS_DEPLOYMENT_TARGET
environment variable to specify that the target is the iOS simulator.
Besides updating the test for this, I also added a few more tests for the
iOS linker options.

David Majnemer a586eb2c70 CodeGen: FieldMemcpyizer didn't handle copies starting inside bitfields
It's possible to construct cases where the first field we are trying to
copy is in the middle of an IR field.  In some complicated cases, we
would fail to use an appropriate offset inside the object.  Earlier
builds of clang seemed to miscompile the code by copying an insufficient
number of bytes.  Up until now, we would assert: the copying offset was
insufficiently aligned.

This fixes PR21232.

Rafael Espindola b275797e31 llvm-ar: Start adding support for mri scripts.
I was quiet surprised to find this feature being used. Fortunately the uses
I found look fairly simple. In fact, they are just a very verbose version
of the regular ar commands.

Start implementing it then by parsing the script and setting the command
variables as if we had a regular command line.

This patch adds just enough support to create an empty archive and do a bit
of error checking. In followup patches I will implement at least addmod
and addlib.

From the description in the manual, even the more general case should not
be too hard to implement if needed. The features that don't map 1:1 to
the simple command line are

* Reading from multiple archives.
* Creating multiple archives.

Mark Heffernan 2beab5f0b4 This patch de-pessimizes the calculation of loop trip counts in
ScalarEvolution in the presence of multiple exits. Previously all
loops exits had to have identical counts for a loop trip count to be
considered computable. This pessimization was implemented by calling
getBackedgeTakenCount(L) rather than getExitCount(L, ExitingBlock)
inside of ScalarEvolution::getSmallConstantTripCount() (see the FIXME
in the comments of that function). The pessimization was added to fix
a corner case involving undefined behavior (pr/16130). This patch more
precisely handles the undefined behavior case allowing the pessimization
to be removed.

ControlsExit replaces IsSubExpr to more precisely track the case where
undefined behavior is expected to occur. Because undefined behavior is
tracked more precisely we can remove MustExit from ExitLimit. MustExit
was used to track the case where the limit was computed potentially
assuming undefined behavior even if undefined behavior didn't necessarily
occur.

Fixes a logic error in the MachineScheduler found by Steve Montgomery (and

Bill Schmidt 59eb767e11 [PowerPC] Add feature for Power8 vector extensions
The current VSX feature for PowerPC specifies availability of the VSX

operations have improved performance.

This patch adds a feature to provide access to the new instructions
and performance capabilities of Power8.  For compatibility with GCC,
the feature is controlled via a new -mpower8-vector switch, and the
feature causes the __POWER8_VECTOR__ builtin define to be generated by
