llvm-svn: 171279

Fixed version of r171273.

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

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

No functionality change.

This changes formatting from:

inline namespace X {
  class A {
  };
}

to:

inline namespace X {
class A {
};
}

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.

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.

This is done to avoid odd test failures, like the one fixed in r171243.

* 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" }

This test did not test anything at all (except for opt crashing, but that was
not the reason why it was added).

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.

assert(Condition
       && "Text");

->

assert(Condition &&
       "Text);

This aligns Polly with the style used in LLVM.

llvm-svn: 171242

We fix the following formatting problems found by clang-format:

  - 80 cols violations
  - Obvious problems with missing or too many spaces
  - multiple new lines in a row

clang-format suggests many more changes, most of them falling in the following
two categories:

  1) clang-format does not at all format a piece of code nicely

  2) The style that clang-format suggests does not match the style used in
     Polly/LLVM

I consider differences caused by reason 1) bugs, which should be fixed by
improving clang-format. Differences due to 2) need to be investigated closer
to understand the cause of the difference and the solution that should be taken.
