This was caused by the code deciding the number of fields in the byref structure using a different test to the part of the code creating the GEPs into said structure.

This allows us to keep passing reduced masks to SimplifyDemandedBits, but
know about all the bits if SimplifyDemandedBits fails. This allows instcombine
to simplify cases like the one in the included testcase.

Provides an API to run clang tools (FrontendActions) as standalone tools,
or repeatedly in-memory in a process. This is useful for unit-testing,
map-reduce style applications, source transformation daemons or command line
tools.
The ability to run over multiple translation units with different command
line arguments enables building up refactoring tools that need to apply
transformations across translation unit boundaries.
See tools/clang-check/ClangCheck.cpp for an example.

a type specifier and can be combined with unsigned. This allows libstdc++4.7 to
be used with clang in c++98 mode.
Several other changes are still required for libstdc++4.7 to work with clang in
c++11 mode.

be sure to perform the argument type adjustments in
[temp.deduct.call]p2, e.g., array decay.
And, when performing these deductions in the context of 'auto', make
sure that we're deducing the P' in std::initializer_list<P'> rather
than the whole initializer list.
Together, this makes code like
for( auto s : {"Deferred", "New", "Open", "Review"}) { }
work properly.

Fixes a bogus "_Pragma takes a parenthesized string literal" error when
expanding consecutive _Pragmas in a macro argument.

for converting an empty list to a scalar, be sure to initialize
the source and destination types so that comparison of conversion
sequences will work in case there are multiple viable candidates.

keep the latter.
No test. This was noticed when poking around something else with GDB. I'm not
able to figure out a testcase that would break due to this bug. Sorry.

svn r145378 inadvertently changed the destination for the Embedded target
in the makefile. Add a "/Developer" suffix to DSTROOT to compensate.

So far all of configure tests have been run against the default SDK and
architecture, regardless of what is actually being built. We've gotten
lucky until now. <rdar://problem/11112479>

a view over the contents of a DeclContext without exposing the implementation
details of the StoredDeclsMap. Use this in LookupVisibleDecls to find the
visible declarations. Fixes PR12339!

When folding X == X we need to check getBooleanContents() to determine if the
result is a vector of ones or a vector of negative ones.
I tried creating a test case, but the problem seems to only be exposed on a
much older version of clang (around r144500).

Infinite recursion was happening when DiagnoseInvalidRedeclaration
called ActOnFunctionDeclarator to check if a typo correction works when
the correction was just to the nested-name-specifier because the wrong
DeclContext was being passed in. Unlike a number of functions
surrounding typo correction, the DeclContext passed in for a function is
the context of the function name after applying any nested name
specifiers, not the lexical DeclContext where the
function+nested-name-specifier appears.
