users over to the new one. No sense maintaining this "compatibility"
layer it seems.

Implement the old API in terms of the new one. This simplifies the
implementation on Windows which can now re-use the self_process's once
initialization.

llvm-svn: 171330

llvm-svn: 171327

The new code is an improved copy of the code I deleted from Analysis/Loads.cpp.
One less compute-constant-gep-offset implementation. yay :)

recommit r171298 (add support for PHI nodes to ObjectSizeOffsetVisitor). Hopefully with bugs corrected now.

llvm-svn: 171325

This reverts r171298. Breaks clang selfhost.

llvm-svn: 171318

Also add an assert to avoid confusion in the code where is known that C1 <= C2.

Fix a truly odd namespace qualifier that was flat out wrong in the
process. The fully qualified namespace would have been
llvm::sys::TimeValue, llvm::TimeValue makes no sense.

The coding style used here is not LLVM's style because this is modeled
after a Boost interface and thus done in the style of a candidate C++
standard library interface. I'll probably end up proposing it as
a standard C++ library if it proves to be reasonably portable and
useful.

This is just the most basic parts of the interface -- getting the
process ID out of it. However, it helps sketch out some of the boiler
plate such as the base class, derived class, shared code, and static
factory function. It also introduces a unittest so that I can
incrementally ensure this stuff works.

However, I've not even compiled this code for Windows yet. I'll try to
fix any Windows fallout from the bots, and if I can't fix it I'll revert
and get someone on Windows to help out. There isn't a lot more that is
mandatory, so soon I'll switch to just stubbing out the Windows side and
get Michael Spencer to help with implementation as he can test it
directly.

promoting a store in a loop.  This was noticed when working on PR14753,
but isn't directly related.

PR14753

llvm-svn: 171279

llvm-svn: 171272

Remove the getAttributesAtIndex and getNumAttrs methods in favor of using the getAttrSomewhere predicate. This prevents the uses of 'Attribute' as a collection of attributes.

llvm-svn: 171271

if C1 and C2 differ only with one bit.
Fixes PR14708.

llvm-svn: 171270

Fixes pr14751.

Patch by Kai; Thanks!

The later API is nicer than the former, and is correct regarding wrap-around offsets (if anyone cares).
There are a few more places left with duplicated code, which I'll remove soon.

directly.

This is in preparation for removing the use of the 'Attribute' class as a
collection of attributes. That will shift to the AttributeSet class instead.

LCSSA PHIs may have undef values. The vectorizer updates values that are used by outside users such as PHIs.
The bug happened because undefs are not loop values. This patch handles these PHIs.

PR14725

llvm-svn: 171251

* One that accepts a single Attribute::AttrKind.

* One that accepts an Attribute::AttrKind plus a list of values. This is for
  attributes defined like this:

    #1 = attributes { align = 4 }

* One that accepts a string, for target-specific attributes like this:

    #2 = attributes { "cpu=cortex-a8" }

llvm-svn: 171249

stored here is of a certain kind. This is in preparation for when an Attribute
object represents a single attribute, instead of a bitmask of attributes.

already uniquified.

Note: This will be expanded in the future to add more than just one pointer
value.

Remove intrinsic specific instructions for (V)SQRTPS/PD. Instead lower to target-independent ISD nodes and use the existing patterns for those.

llvm-svn: 171237

llvm-svn: 171229

Remove intrinsic specific instructions for SSE/SSE2/AVX floating point max/min instructions. Lower them to target specific nodes and use those patterns instead. This also allows them to be commuted if UnsafeFPMath is enabled.
