has more than one function with a body.  This
prevents declarations e.g. of blocks from being
passed to the IRInterpreter; they must pass
through to the JIT.

Fix a conversion to incomplete type bug -- The error message now specifically states that the type is incomplete and points to the forward declaration of the incomplete type.

correctly.  We have been getting lucky since most
expressions generate only one section (or the first
code section contains all the code), but sometimes
it actually matters.

When we store values for reversed induction stores we must not store the
reversed value in the vectorized value map. Another instruction might use this
value.

This fixes 3 test cases of PR16455.

bother checking if a region is safe to use.  In
cases where regions need to be synthesized rather
than properly allocated, the memory reads required
to determine whether the area is used are

- insufficient, because intermediate locations
  could be in use, and

- unsafe, because on some platforms reading from
  memory can trigger events.

All this only makes a difference on platforms
where memory allocation in the target is impossible.
Behavior on platforms where it is possible should
stay the same.

SLP: When searching for vectorization opportunities scan the blocks in post-order because we grow chains upwards.

Armed with a much better understanding of what
TemplateSpecializationTypeLoc::initializeArgLocs actually does, I now
understand that it's fine to just use an empty TemplateArgumentLocInfo
for Integral, Declaration, and NullPtr TemplateArguments.

Fixes PR14281. (The testcases are actually derived from libcxx_test in
deduction-crash.cpp because the original testcase was impossible to reduce.)

In InstCombine{AddSub,MulDivRem} convert APFloat.isFiniteNonZero() && !APFloat.isDenormal => APFloat.isNormal.

llvm-svn: 185037

Currently inside APFloat fcNormal still implies the old definition of Normal
(i.e. isFiniteNonZero) instead of the proper IEEE-754R definition that the
external method isNormal() uses.

This patch prepares for the internal switch inside APFloat by converting all
references that check if a category is fcNormal directly with an indirect call
via isFiniteNonZero().

Option groups don't have prefixes.  Option dumping is basically dead

ARM: Proactively ensure that the LowerCallResult hack for 'this'-returns is not used for incompatible calling conventions.

(Currently, ARM 'this'-returns are handled in the standard calling convention case by treating R0 as preserved and doing some extra magic in LowerCallResult; this may not apply to calling conventions added in the future so this patch provides and documents an interface for indicating such)

The old implementation of ms_struct in RecordLayoutBuilder was a
complete mess: it depended on complicated conditionals which didn't
really reflect the underlying logic, and placed a burden on users of
the resulting RecordLayout. This commit rips out almost all of the
old code, and replaces it with simple checks in
RecordLayoutBuilder::LayoutBitField.

This commit also fixes <rdar://problem/14252115>, a bug where class
inheritance would cause us to lay out bitfields incorrectly.
