Duncan P. N. Exon Smith 353c84e747 CodeGen: Avoid implicit conversion in MachineInstrBuilder, NFC
Avoid another implicit conversion from MachineInstrBundleIterator to
MachineInstr*, this time in MachineInstrBuilder.h (this is in pursuit of
PR26753).

Tobias Grosser 4fb9e51664 ScopInfo: Drop some debug statements
This debug output distracts from the -debug-only=polly-scops output. As it is
rather verbose and only really needed for debugging the domain construction
I drop this output. The domain construction is meanwhile stable enough to
not require regular debugging.

Duncan P. N. Exon Smith 3ac9cc6156 CodeGen: Take MachineInstr& in SlotIndexes and LiveIntervals, NFC
Take MachineInstr by reference instead of by pointer in SlotIndexes and
the SlotIndex wrappers in LiveIntervals.  The MachineInstrs here are
never null, so this cleans up the API a bit.  It also incidentally
removes a few implicit conversions from MachineInstrBundleIterator to
MachineInstr* (see PR26753).

At a couple of call sites it was convenient to convert to a range-based
for loop over MachineBasicBlock::instr_begin/instr_end, so I added
MachineBasicBlock::instrs.

Tobias Grosser abafafe07c ScopInfo: Add function to invalidate ScopArrayInfo object
In case the underlying basepointer of a ScopArrayInfo object is moved to another
module while the scop is still processed is it necessary to free dependent
ScopArrayInfo objects as they might otherwise be looked accidentally when a
new llvm basepointer value is reassigned the very same memory location as the
llvm value that has been moved earlier.

This function is not yet used in Polly itself, but is useful for external users.

Sean Silva ea399f0242 [instrprof] Use __{start,stop}_SECNAME on PS4 too.
Summary:
The PS4 linker seems to handle this fine.

Hi David, it seems that indeed most ELF linkers support
__{start,stop}_SECNAME, as our proprietary linker does as well.

This follows the pattern of r250679 w.r.t. the testing.

Maggie, Phillip, Paul: I've tested this with the PS4 SDK 3.5 toolchain
prerelease and it seems to work fine.

Chandler Carruth ad8cb382fa [LICM] Teach LICM how to handle cases where the alias set tracker was
merged into a loop that was subsequently unrolled (or otherwise nuked).

In this case it can't merge in the ASTs for any remaining nested loops,
it needs to re-add their instructions dircetly.

The fix is very isolated, but I've pulled the code for merging blocks
into the AST into a single place in the process. The only behavior
change is in the case which would have crashed before.

This fixes a crash reported by Mikael Holmen on the list after r261316
restored much of the loop pass pipelining and allowed us to actually do
this kind of nested transformation sequenc. I've taken that test case
and further reduced it into the somewhat twisty maze of loops in the
included test case. This does in fact trigger the bug even in this
reduced form.

Richard Smith e5a91464bc Fix bug in using shadow decl checking: a using shadow decl should not conflict
with a prior UsingDecl -- those should not even really be found by the lookup
here, except that we use the same lookup results for two different checks, and
the other check needs them.

This happens to work in *almost all* cases, because either the lookup results
list the UsingDecl first (and the NonTag result gets replaced by something
else) or because the problematic declaration is a function (which causes us to
use different logic to detect conflicts). This can also be triggered from a
state only reachable through modules (where the name lookup results can contain
multiple UsingDecls in the same scope).

Philip Reames adf0e35308 [LVI] Extend select handling to catch min/max/clamp idioms
Most of this is fairly straight forward. Add handling for min/max via existing matcher utility and ConstantRange routines.  Add handling for clamp by exploiting condition constraints on inputs.  

Note that I'm only handling two constant ranges at this point. It would be reasonable to consider treating overdefined as a full range if the instruction is typed as an integer, but that should be a separate change.

Sanjay Patel 1ace99351f [x86, InstCombine] transform x86 AVX masked stores to LLVM intrinsics
The intended effect of this patch in conjunction with:
http://reviews.llvm.org/rL259392
http://reviews.llvm.org/rL260145

is that customers using the AVX intrinsics in C will benefit from combines when
the store mask is constant:

void mstore_zero_mask(float *f, __m128 v) {
  _mm_maskstore_ps(f, _mm_set1_epi32(0), v);
}

void mstore_fake_ones_mask(float *f, __m128 v) {
  _mm_maskstore_ps(f, _mm_set1_epi32(1), v);
}

void mstore_ones_mask(float *f, __m128 v) {
  _mm_maskstore_ps(f, _mm_set1_epi32(0x80000000), v);
}

void mstore_one_set_elt_mask(float *f, __m128 v) {
  _mm_maskstore_ps(f, _mm_set_epi32(0x80000000, 0, 0, 0), v);
}

...so none of the above will actually generate a masked store for optimized code.
