Warren Hunt 42be77672a Correctly check for distructors when realizing vtordisps
This patch fixes the distructor test when checking for vtordisp requirements in 
microsoft record layout.  A test case is also included.

Howard Hinnant 58af7e177c r192075 broke the buildbot at
http://lab.llvm.org:8013/builders/libcxx_clang-x86_64-darwin11-RA

lit.py: <string>:230: note: inferred use_system_lib as: False
lit.py: <string>:247: fatal: C++ ABI setting None unsupported for tests

cxx_abi is geting set to None, and the lit script errors out shortly after
that.  This patch changes the default of cxx_abi from None to 'libcxxabi'.
This is likely not the right way to fix this problem.  However it gets the
buildbot running again.  Improvements to this fix are welcome.

Will Dietz 5cb7f4e3f2 MachineSink: Fix and tweak critical-edge breaking heuristic.
Per original comment, the intention of this loop
is to go ahead and break the critical edge
(in order to sink this instruction) if there's
reason to believe doing so might "unblock" the
sinking of additional instructions that define
registers used by this one.  The idea is that if
we have a few instructions to sink "together"
breaking the edge might be worthwhile.

This commit makes a few small changes
to help better realize this goal:

First, modify the loop to ignore registers
defined by this instruction.  We don't
sink definitions of physical registers,
and sinking an SSA definition isn't
going to unblock an upstream instruction.

Second, ignore uses of physical registers.
Instructions that define physical registers are
rejected for sinking, and so moving this one
won't enable moving any defining instructions.
As an added bonus, while virtual register
use-def chains are generally small due
to SSA goodness, iteration over the uses
and definitions (used by hasOneNonDBGUse)
for physical registers like EFLAGS
can be rather expensive in practice.
(This is the original reason for looking at this)

Finally, to keep things simple continue
to only consider this trick for registers that
have a single use (via hasOneNonDBGUse),
but to avoid spuriously breaking critical edges
only do so if the definition resides
in the same MBB and therefore this one directly
blocks it from being sunk as well.
If sinking them together is meant to be,
let the iterative nature of this pass
sink the definition into this block first.

Update tests to accomodate this change,
add new testcase where sinking avoids pipeline stalls.

Serge Pavlov c0cd80fb20 Do not use typo correction that is unaccessible.
This patch fixes PR17019. When doing typo correction, Sema::CorrectTypo uses
correction already seen for the same typo. This causes problems if that
correction is from another scope and cannot be accessed in the current.

Matheus Almeida b74293dc55 [mips][msa] Direct Object Emission of INSERT.{B,H,W} instruction.
INSERT is the first type of MSA instruction that requires a change to the way
MSA registers are parsed. This happens because MSA registers may be suffixed by
an index in the form of an immediate or a general purpose register. The changes
to parseMSARegs reflect that requirement.

Alexey Samsonov df6e6569c0 [ASan] Don't die with internal ASan error on large buffer overflows
Summary:
Out-of-bound access may touch not-yet allocated or already freed
and recycled from quarantine chunks. We should treat this situation as
a "free-range memory access" and avoid printing any data about that
irrelevant chunk (which may be inconsistent).

This should fix https://code.google.com/p/address-sanitizer/issues/detail?id=183
