For a call to not return in to the stackmap shadow, the shadow must end with the call.
To do this, we must insert any required nops *before* the call, and not after it.

Looks like some builds were not happy with the potentially-throwing move
constructor that was added in r220723, and reached for the implicitly
deleted copy constructor instead.

For targets that end it `redhat-linux` and `suse-linux` manually add the `-gnu`
section of the target since `linux-gnu` is needed in the testsuite.
This patch also moves the removal of minor and patchlevel numbers from OSX
triples to be handled when deducing the triple instead of when adding available
features.

Summary:
Some declarations do not have a declaration context, like TranslationUnitDecl.
Fix hasDeclContext() to not segfault on these nodes.

Summary: This fixes ODR violations in C++03 mode in test/localization/locale.stdcvt. The special case for linux was introduced in 2010 before clang always defined __char16_t and __char32_t.

The comma operators in the test iterators give better error messages when they
are deleted as opposed to not defined. Delete these functions when possible.

This is a minor change to use the immediate version when the operand is a null
value. This should get rid of an unnecessary 'mov' instruction in debug
builds and align the code more with the one generated by SelectionDAG.
This fixes rdar://problem/18785125.

To avoid emitting too many nops, a stackmap shadow can include emitted instructions in the shadow, but these must not include branch targets.
A return from a call should count as a branch target as patching over the instructions after the call would lead to incorrect behaviour for threads currently making that call, when they return.

The pattern matching for a 'ConstantInt' value was too restrictive. Checking for
a 'Constant' with a bull value is sufficient for using an 'cbz/cbnz' instruction.
This fixes rdar://problem/18784732.

Summary:
We should avoid a tail padding not only if the last field
has zero size but also if the last field is a struct with a flexible array.
If/when http://reviews.llvm.org/D5478 is committed,
this will also handle the case of structs with zero-sized arrays.

An evil user might overload operator comma. Use a void cast to make sure any user overload is not selected.

PseudoTerminal.cpp uses a dummy implementation of posix_openpt for Windows. This
implementation just returns 0. So m_master_fd is 0. But destructor calls 'close'
on m_master_fd. This 'close' calls seems un-necessary as m_master_fd was never
opened in first place and calling 'close' on 0 can have other un-intended
consequences.
I am committing it as obvious as it is only a one-liner. Long term, we may want
to refactor this class.

This fixes a bug where the input register was not defined for the 'tbz/tbnz'
instruction. This happened, because we folded the 'and' instruction from a
different basic block.

At higher optimization levels the LLVM IR may contain more complex patterns for
loads/stores from/to frame indices. The 'computeAddress' function wasn't able to
handle this and triggered an assertion.
This fix extends the possible addressing modes for frame indices.

matches of the typo.
Also be more proactive about checking a correction's visibility so that
a correction requiring a module import can be distinguished from the
original typo even if it looks identical. Otherwise the correction will
be excluded and the diagnostic about needing the module import won't be
emitted.
Note that no change was made to checkCorrectionVisibility other than
moving where it is at in SemaLookup.cpp.

Part of the infrastructure is a map from a TypoExpr to the Sema-specific
state needed to correct it, along with helpers to ease dealing with the
state.
The the typo count is propagated up the stack of
ExpressionEvaluationContextRecords when one is popped off of to
avoid accidentally dropping TypoExprs on the floor. For example,
the attempted correction of g() in test/CXX/class/class.mem/p5-0x.cpp
happens with an ExpressionEvaluationContextRecord that is popped off
the stack prior to ActOnFinishFullExpr being called and the tree
transform for TypoExprs being run.
llvm-svn: 220695
Two additional methods are provided: one to return the current
correction (the last correction returned by getNextCorrection), and one
to "reset" the state so that getNextCorrection will return the previous
corrections before returning any new corrections.
Also ensure that all TypoCorrections have valid source ranges.
llvm-svn: 220694
This makes it available outside of SemaLookup.cpp, as
needed for the forthcoming TypoExpr AST node which will
keep a TypoCorrectionConsumer that provides the possible
typo corrections for that TypoExpr.

Improve the documentation for vim integration of clang-format. Prefer the use
of <c-o> to do the normal mode command execution to avoid side-effects of the
escape and re-insertion (cursor movement). Tweak the macros to use a double

subprocess.

Summary:
Speed up clang-tidy when profiling in on.
It makes profiling runs twice as fast by reusing the time samples between the
different actions.
It also joins together the sampling of different matchers of the same check.
