Simon Pilgrim 9c1e4123f8 [X86][AVX] 256-bit vector stack unaligned load/stores identification
Under many circumstances the stack is not 32-byte aligned, resulting in the use of the vmovups/vmovupd/vmovdqu instructions when inserting ymm reloads/spills.

This minor patch adds these instructions to the isFrameLoadOpcode/isFrameStoreOpcode helpers so that they can be correctly identified and not be treated as folded reloads/spills.

This has also been noticed by http://llvm.org/bugs/show_bug.cgi?id=18846 where it was causing redundant spills - I've added a reduced test case at test/CodeGen/X86/pr18846.ll

Enrico Granata 49bfafb510 Shuffle APIs around a little bit, so that if you pass custom summary options, we don't end up caching the summary hence obtained. You may want to obtain an uncapped summary, but this should not be reflected in the summary we cache. The drawback is that we don't cache as aggressively as we could, but at least you get to have different summaries with different options without having to reset formatters or the SBValue at each step

Nick Kledzik 2020efb9fe [mach-o] for 32-bit arm, in -r mode support B (not BL) to undefined symbol
When fixing up BL instructions, the linker has to compare the thumbness of the
target to decide if the instruction needs to be converted to BLX.  But with B
instruction there is no BX, so the linker asserts if the target is not the
same thumbness. This assert was firing in -r mode when the target was undefined
which it interpreted as being non-thumb.

Test case change is to add a B (in both thumb and arm code) to an undefined
symbol and round trip through -r mode.

Fariborz Jahanian ef202d96c7 [Sema] Patch to issue warning on comparing parameters with
nonnull attribute when comparison is always true/false. 
Original patch by Steven Wu. I have added extra code to prevent issuing of
warning  when the nonnull parameter is modified prior to the comparison.
This addition prevents false positives in the most obvious cases.
There may still be false positive warnings in some cases (as one of my tests
indicates), but benefit far outweighs such cases. rdar://18712242

Matt Arsenault 162c1010bd R600/SI: Move SIFixSGPRCopies to inst selector passes
This should expose more of the actually used VALU
instructions to the machine optimization passes.

This also should help getting i1 handling into a better state.
For not entirly understood reasons, this fixes the split-scalar-i64-add.ll
test where a 64-bit add would only partially be moved to the VALU
resulting in use of undefined VCC.

Juergen Ributzka 7a7c4684e4 [AArch64] Don't optimize all compare instructions.
"optimizeCompareInstr" converts compares (cmp/cmn) into plain sub/add
instructions when the flags are not used anymore. This conversion is valid for
most instructions, but not all. Some instructions that don't set the flags
(e.g. sub with immediate) can set the SP, whereas the flag setting version uses
the same encoding for the "zero" register.

Update the code to also check for the return register before performing the
optimization to make sure that a cmp doesn't suddenly turn into a sub that sets
the stack pointer.

I don't have a test case for this, because it isn't easy to trigger.

Philip Reames 018dbf18c4 Tweak EarlyCSE to recognize series of dead stores
EarlyCSE is giving up on the current instruction immediately when it recognizes that the current instruction makes a previous store trivially dead. There's no reason to do this. Once the previous store has been deleted, it's perfectly legal to remember the value of the current store (for value forwarding) and the fact the store occurred (it could be dead too!).
