breakage with builds without X86-support.

This change adds MemorySanitizer annotations to BumpPtrAllocator to
improve report quality.

That function doesn't make sense anymore because there's only one attribute per
Attribute object now.

Fixed a mistake in my previous commit where I changed the wording slightly and forgot to undo the change after changing my mind and deciding to only commit the style changes.

llvm-svn: 174041

section Global Variable so that the style matches the other keywords in
said section.

It broke many hosts to crash.

as well.

llvm-svn: 174028

it isn't really an AliasAnalysis concept, and ValueTracking has similar things
that it could plausibly share code with some day.

llvm-svn: 174027

The Attribute::hasAttributes() is kind of meaningless since an Attribute can
have only one attribute. And we would rather people use the 'operator=='
instead of Attribute::hasAttribute().

llvm-svn: 174026

reference to a pointer, so that it can handle the case where DataLayout
is not available and behave conservatively.

llvm-svn: 174024

llvm-svn: 174023

Makefile.config does not have the value for ENABLE_THREADS substituted as the
variable is called LLVM_ENABLE_THREADS within configure.ac.  This was pointed
out by zygoloid over IRC.

 - Also, add a test for it.

Filecheckized 2x tests in SimplifyCFG and removed their date prefix to fit with current llvm style for test names.

llvm-svn: 174011

The AttrBuilder is there to build up multiple attributes. The Attribute class
represents only one attribute at a time. So remove this unnecessary builder
creator method.

register for inline asm. This conforms to how gcc allows for effective
casting of inputs into gprs (fprs is already handled).

Several places were still treating the Attribute object as respresenting
multiple attributes. Those places now use the AttributeSet to represent
multiple attributes.

with an assert instead of failing and requiring callers to check for failure.

for example, a one-past-the-end pointer from one global variable may
be equal to the base pointer of another global variable.

As a bonus I put in some extra checks to make sure that we are identifying the
machine word of various Mac OS X/iOS targets appropriately.

llvm-svn: 173994

On systems which support the QPX vector instructions, the stack must be
32-byte aligned.

llvm-svn: 173993

llvm-svn: 173992

There are still places which treat the Attribute object as a collection of
attributes. I'm systematically removing them.
