The new version reads d_reclen for (struct dirent) size.

Add pseudo conditional store instructions, so that we use:

    branch foo:
    store
foo:

instead of:

    load
    branch foo:
    move
foo:
    store

z196 has real 32-bit and 64-bit conditional stores, but we don't use
any z196 instructions yet.

This is essentially reverting one piece of 184793 to try to fix one of Apple's
buildbots.  I will check with Eric to see if this is OK or if we need to find
some other solution.

There are a few valid situation where we care about the structure inside a
directory, but not about the directory itself. A simple example is for unit
testing directory traversal.

PathV1 had a function like this, add one to V2 and port existing users of the
created temp file and delete it hack to using it.

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.

[APFloat] Added unittest for APFloat.divide that checks special cases, result categories, and result statuses.

The Builtin attribute is an attribute that can be placed on function call site that signal that even though a function is declared as being a builtin,

Found a race condition when killing an application where the state could be set to exited by the waitpid_thread() _before_ we call task resume (via MachProcess::PrivateResume()) in MachProcess::Kill().

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.

SLP: Dont erase instructions during vectorization because it prevents the outerloops from iterating over the instructions.

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().

side-effect is not sequenced before its value computation. Also fix a
mishandling of ?: expressions where the condition is constant that was
exposed by the tests for this.

Option groups don't have prefixes.  Option dumping is basically dead
code unless there is something wrong with the option table, so this
isn't an important crasher.
