polution problems from system headers.  Patch by Nathan Keynes!

llvm-svn: 52682

"Support for Objective-C message sends which return structures.  Also includes a small fix for constant string handling that should have been in the last patch (sorry!) and a hook for generating selectors (rest of this implementation to follow in the next patch)."

Patch by David Chisnall!

"This is a small fix for a bug where static object instances were being incorrectly generated.  The bug was caused by my inability to read the GNU libobjc source and is only apparent when JITing code (static compilation does not expose the bug due to the data layout of other globals)."

Update serialization for ObjCMessageExpr to handle additional bit-swizziling of receiver information.

Also add a testcase to reproduce the gcc bootstrap failure in very much reduced form.

ObjCMessageExpr objects that represent messages to class methods now can contain the ObjCInterfaceDecl* of the target class if it was available when the ObjCMessageExpr object was constructed.  The original interfaces of the class has been preserved (requiring no functionality changes from clients), but now a "getClasSInfo" method returns both the ObjCInterfaceDecl* and IdentifierInfo* of the target class.

We will keep the old projects/llvm-test working for existing installs.

The changes to configure are made manually, since I lack autoconf-2.6. Someone
might want to run AutoGen.sh to see if that changes anything.

All of LLVM's testing features are now referred to as the "Testing
infrastructure", the DejaGNU tests are just that, and the whole program tests
are referred to as the "test suite".

Test commit: changed the forward declaration of FieldDeclarator from class to struct to be coherent with its definition (DeclSpec.h)

If it's determined safe, remat MOV32r0 (i.e. xor r, r) and others as it is instead of using the longer MOV32ri instruction.

'There's not much to say about this patch, it just adds the Arch Linux
gcc 4.3.1 header paths for i686 and amd64. The patch was generated
using "svn diff" with clang at revision 52660. The paths aren't
distribution-specific, so they should work for all Linux distributions
using the default(?) names like "i686-pc-linux-gnu".'

general solution possible, but it's a fairly simple one.
Based on a patch from the OpenGTL project!

where there is a use in a PHI node that's a predecessor to the defining
block. We don't want to mark all predecessors as having the value "alive" in
this case. Also, the assert was too restrictive and didn't handle this case.

needs arbitrary-element removal.

llvm-svn: 52654

Added ObjCSummaryCache, a new summary cache object to cache summaries for Objective-C methods.  Instead of mapping from Selectors -> Summaries, we will now map from (ObjCInterfaceDecl*,Selectors) -> Summaries.  This will allow more nuanced summary generation.  This patch just swaps in the new data structure; the rest of the code works as before by allowing the ObjCInterfaceDecl* to be null.

llvm-svn: 52653

Add getScaledIntervalSize, which gives a measure of the size of an interval that is independent of the scaling of
the function due to empty index slots.  This is suitable for use in backend heuristics that need to reason about the density
of an interval.

llvm-svn: 52651

Rename summary methods for "instance methods" to "class methods" (the names got screwed up).  No functionality change.

llvm-svn: 52650

Use getMBBEndIdx rather than assuming that the end is right after the last instruction in the block.

in the presence of out-of-loop users of in-loop values and the trip
count is not a known multiple of the unroll count, and to be a bit
simpler overall. This fixes PR2253.

Remove option used to debug stack coloring bugs. It's no longer needed since stack coloring is now bug free.
