The root cause is mistakenly taking for granted that
"dyn_cast<Instruction>(a-Value)"
return a non-NULL instruction.

This change is basically just copying changes that we've used for Apple's
clang builds to the script used for building llvmCore. Besides cleaning it
up to use xcrun to locate the proper versions of tools, especially for cross
compiling, it fixes the build to work with newer versions of clang that
honor SDKROOT settings in the environment.

against the developer policy to include this sort of thing as SVN blame
already captures this in a far more fine-grained way.

Like Clang's FixItHint, SMFixIt represents an insertion, replacement, or
removal of source text. One or more fix-its can be emitted as part of
a diagnostic, and will be printed below the source range line to show the
user how they can fix their code.
Currently, the only client of SMFixIt is clang-tblgen; thus, the tests for
this behavior live in clang/test/TableGen/tg-fixits.td. If/when SMFixIt is
adopted within LLVM itself, those tests should be moved to the LLVM suite.

This allows us to produce more precise diagnostics about a certain
superclass, and even provide fixits.

When calling hasProperty() on an instruction inside a bundle, it should
always behave as if IgnoreBundle was passed, and just return properties
for the current instruction.
Only attempt to aggregate bundle properties whan asked about the bundle
header.
The assertion fires on existing ARM test cases without this fix.

Use memcpy to do type punning instead of a cast. A cast or similar
operation through a union breaks strict aliasing rules.

The purpose of this patch is to allow PredicateMethods to be set to something
like "isUImm<8>", calling a C++ template method to reduce code duplication. For
this to work, the PredicateMethod must be mangled into a valid C++ identifier
for insertion into an enum.

requirement when creating stack objects in MachineFrameInfo.
Add CreateStackObjectWithMinAlign to throw error when the minimal alignment
can't be achieved and to clamp the alignment when the preferred alignment
can't be achieved. Same is true for CreateVariableSizedObject.
Will not emit error in CreateSpillStackObject or CreateStackObject.
As long as callers of CreateStackObject do not assume the object will be
aligned at the requested alignment, we should not have miscompile since
later optimizations which look at the object's alignment will have the correct
information.

If the compiler is gcc, disable variants of -Wuninitialized depending
on the gcc version. This gets a lot of false positive warnings out of
the build.
Generate a new configure for the gcc -Wno-uninitialized fix.
Pick up -Wno-uninitialized from configure
Add the option -Wno[-maybe]-uninitialized as determined by configure.
