278bbacd27 ConstantFold: Don't optimize comparisons with weak linkage objects
Consider:
void f() {}
void __attribute__((weak)) g() {}
bool b = &f != &g;

It's possble for g to resolve to f if --defsym=g=f is passed on to the
linker.

a421ac689f SelectionDAG switch lowering: Replace unreachable default with most popular case.
This can significantly reduce the size of the switch, allowing for more
efficient lowering.

I also worked with the idea of exploiting unreachable defaults by
omitting the range check for jump tables, but always ended up with a
non-neglible binary size increase. It might be worth looking into some more.

SimplifyCFG currently does this transformation, but I'm working towards changing
that so we can optimize harder based on unreachable defaults.

ab4ad4f98e Optimize merging of scalar loads for 32-byte vectors [X86, AVX]
Fix the poor codegen seen in PR21710 ( http://llvm.org/bugs/show_bug.cgi?id=21710 ).
Before we crack 32-byte build vectors into smaller chunks (and then subsequently
glue them back together), we should look for the easy case where we can just load
all elements in a single op.

An example of the codegen change is:

From:

vmovss  16(%rdi), %xmm1
vmovups (%rdi), %xmm0
vinsertps       $16, 20(%rdi), %xmm1, %xmm1
vinsertps       $32, 24(%rdi), %xmm1, %xmm1
vinsertps       $48, 28(%rdi), %xmm1, %xmm1
vinsertf128     $1, %xmm1, %ymm0, %ymm0
retq

To:

vmovups (%rdi), %ymm0
retq

a44126f432 Use 32-bit ebp for NaCl64 in a limited case: llvm.frameaddress.
Summary:
Follow up to [x32] "Use ebp/esp as frame and stack pointer":
http://reviews.llvm.org/D4617

In that earlier patch, NaCl64 was made to always use rbp.
That's needed for most cases because rbp should hold a full
64-bit address within the NaCl sandbox so that load/stores
off of rbp don't require sandbox adjustment (zeroing the top
32-bits, then filling those by adding r15).

However, llvm.frameaddress returns a pointer and pointers
are 32-bit for NaCl64. In this case, use ebp instead, which
will make the register copy type check. A similar mechanism
may be needed for llvm.eh.return, but is not added in this change.

6a9a49d7ab [X86] Improved lowering of packed vector shifts to vpsllq/vpsrlq.
SSE2/AVX non-constant packed shift instructions only use the lower 64-bit of
the shift count. 

This patch teaches function 'getTargetVShiftNode' how to deal with shifts
where the shift count node is of type MVT::i64.

Before this patch, function 'getTargetVShiftNode' only knew how to deal with
shift count nodes of type MVT::i32. This forced the backend to wrongly
truncate the shift count to MVT::i32, and then zero-extend it back to MVT::i64.

1a283409bc BFI: Saturate when combining edges to a successor
When a loop gets bundled up, its outgoing edges are quite large, and can
just barely overflow 64-bits.  If one successor has multiple incoming
edges -- and that successor is getting all the incoming mass --
combining just its edges can overflow.  Handle that by saturating rather
than asserting.

This fixes PR21622.
