Most of these are updating the new R600 target and fixing up a few
regressions that have creeped in since the last time I sorted the
includes.

No functionality change.

llvm-svn: 171348

Added DEBUG message when ObjCARC replaces a call which returns its argument verbatim with its argument to temporarily undo an optimization.

Specifically these calls return their argument verbatim, as a low-level
optimization. However, this makes high-level optimizations
harder. We undo any uses of this optimization that the front-end
emitted. We redo them later in the contract pass.

llvm-svn: 171346

Added DEBUG messages to the top of several processing loops in ObjCARC.cpp that emit what instructions are being visited.

This is a part of a larger effort of adding DEBUG messages to the ARC
Optimizer Backend.

llvm-svn: 171345

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

llvm-svn: 171310

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

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.

llvm-svn: 171253

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.

[ASan] Fix lifetime intrinsics handling. Now for each intrinsic we check if it describes one of 'interesting' allocas. Assume that allocas can go through casts and phi-nodes before apperaring as llvm.lifetime arguments

llvm-svn: 171153

If all of the write objects are identified then we can vectorize the loop even if the read objects are unidentified.

such as by a compiler warning, a check in clang -fsanitizer=undefined, being
optimized to unreachable, or a combination of the above. PR14722.

llvm-svn: 171119

LoopVectorizer: Optimize the vectorization of consecutive memory access when the iteration step is -1

llvm-svn: 171114

Origin alignment is as high as the alignment of the corresponding application
location, but never less than 4.

llvm-svn: 171110

llvm-svn: 171109

For the time being this includes only some dummy test cases. Once the
generic implementation of the intrinsics cost function does something other
than assuming scalarization in all cases, or some target specializes the
interface, some real test cases can be added.

Also, for consistency, I changed the type of IID from unsigned to Intrinsic::ID
in a few other places.

VectorType::getInteger() can not be used with them, because pointer size
depends on the target.

When the backend is used from clang, it should produce proper diagnostics
instead of just printing messages to errs(). Other clients may also want to
register their own error handlers with the LLVMContext, and the same handler
should work for warnings in the same way as the existing emitError methods.

Change 'AttrVal' to 'AttrKind' to better reflect that it's a kind of attribute instead of the value of the attribute.
