when using Python < 2.7.0. This is the case on Snow Leopard, where the tools are always
installed in /Developer. This isn't a proper fix for really figuring out where Xcode
is installed, but should work to fix an obvious problem on Snow Leopard.

This code is very sensitive to the difference between "columns" as printed
and "bytes" (SourceManager columns). All variables are now named explicitly
and our assumptions are (hopefully) documented as both comment and assertion.
Whether parseable fixits should use byte offsets or Unicode character counts
is pending discussion on the mailing list; currently the implementation uses
bytes (and has no problems on lines containing multibyte characters).
This has been added to the user manual.

CmpRuns can be used for static analyzer bug report comparison. However,
we want to make sure external users do not rely on the way bugs are
represented (plist files). Make sure that we have a user
friendly/documented API for CmpRuns script.

as an array of its base class TemplateArgument. Switch the const
TemplateArgument* parameters of InstantiatingTemplate's constructors to
ArrayRef<TemplateArgument> to prevent this from happening again in the future.

being a property of a canonical type to being a property of the fully-sugared
type. This should only make a difference in the case where an alias template
ignores one of its parameters, and that parameter is an unexpanded parameter
pack.

struct __attribute__((visibility("hidden"))) zed {
};
struct __attribute__((visibility("hidden"))) zed;
Which is a bit silly and got a lot noisier now that we correctly handle
visibility pragmas. This patch fixes that and also has some extra quality
improvements:
* We now produce an error instead of a warning for
struct __attribute__((visibility("hidden"))) zed {
};
struct __attribute__((visibility("default"))) zed;
* The "after definition" warning now points to the new attribute that is
ignored instead of pointing to the declaration.

instead push the terminator for the branch down into the basic blocks of the subexpressions of '&&' and '||'
respectively. This eliminates some artifical control-flow from the CFG and results in a more
compact CFG.
Note that this patch only alters the branches 'while', 'if' and 'for'. This was complex enough for
one patch. The remaining branches (e.g., do...while) can be handled in a separate patch, but they
weren't immediately tackled because they were less important.
It is possible that this patch introduces some subtle bugs, particularly w.r.t. to destructor placement.
I've tried to audit these changes, but it is also known that the destructor logic needs some refinement
in the area of '||' and '&&' regardless (i.e., their are known bugs).

AVX). Currently, if no aligned attribute is specified the alignment of a vector is
inferred from its size. Thus, very large vectors will be over-aligned with no
benefit. Target owners should set this target max.

intrinsics with target-indepdent intrinsics. The first instruction(s) to be
handled are the vector versions of count leading zeros (ctlz).
The changes here are to clang so that it generates a target independent
vector ctlz when it sees an ARM dependent vector ctlz. The changes in llvm
are to match the target independent vector ctlz and in VMCore/AutoUpgrade.cpp
to update any existing bc files containing ARM dependent vector ctlzs with
target-independent ctlzs. There are also changes to an existing test case in
llvm for ARM vector count instructions and a new test for the bitcode upgrade.

There is deliberately no test for the change to clang, as so far as I know, no
consensus has been reached regarding how to test neon instructions in clang;
