576f62c1ea TLI: Microoptimize calls to strlen+memcmp to strncmp.
The strlen+memcmp was hidden in a call to StringRef::operator==. We check if
there are any null bytes in the string upfront so we can simplify the comparison
Small speedup when compiling code with many function calls.

d787c047bc R600/SI: Use source scheduler
This is certainly not the last word on scheduling for this target, but
right now this allows a few apps to run / finish with radeonsi, most
notably UT2004 / Lightsmark. They fail to compile some shaders with the
default scheduler because it ends up trying to spill registers, which
we don't support yet (and which is probably a bad idea in general for
performance if it can be avoided).

NOTE: This is a candidate for the Mesa stable branch.

- Phi nodes should be replaced/updated after lowering CMOV into branch
  because 'mainMBB' updating operand in Phi node is changed.
- Add EFLAGS in livein before lowering the 2nd CMOV. It's necessary as
  we will reuse the EFLAGS generated before the 1st lowered CMOV, which
  won't clobber EFLAGS. However, we need explicitly specify that.
- '-attr=-cmov' test case are added.

cf70590c38 Add more functions to the TLI.
This patch adds many more functions to the target library information.
All of the functions being added were discovered while doing the migration
of the simplify-libcalls attribute annotation functionality to the
functionattrs pass.  As a part of that work the attribute annotation logic
will query TLI to determine if a function should be annotated or not.

62f38ca141 R600: initial scheduler code
This is a skeleton for a pre-RA MachineInstr scheduler strategy. Currently
it only tries to expose more parallelism for ALU instructions (this also
makes the distribution of GPR channels more uniform and increases the
chances of ALU instructions to be packed together in a single VLIW group).
Also it tries to reduce clause switching by grouping instruction of the
same kind (ALU/FETCH/CF) together.

Vincent Lejeune:
 - Support for VLIW4 Slot assignement
 - Recomputation of ScheduleDAG to get more parallelism opportunities

Tom Stellard:
 - Fix assertion failure when trying to determine an instruction's slot
   based on its destination register's class
 - Fix some compiler warnings

Vincent Lejeune: [v2]
 - Remove recomputation of ScheduleDAG (will be provided in a later patch)
 - Improve estimation of an ALU clause size so that heuristic does not emit cf
 instructions at the wrong position.
 - Make schedule heuristic smarter using SUnit Depth
 - Take constant read limitations into account

Vincent Lejeune: [v3]
 - Fix some uninitialized values in ConstPair
 - Add asserts to ensure an ALU slot is always populated

6c4265a541 The current X86 NOP padding uses one long NOP followed by the remainder in
one-byte NOPs.  If the processor actually executes those NOPs, as it sometimes
does with aligned bundling, this can have a performance impact.  From my
micro-benchmarks run on my one machine, a 15-byte NOP followed by twelve
one-byte NOPs is about 20% worse than a 15 followed by a 12.  This patch
changes NOP emission to emit as many 15-byte (the maximum) as possible followed
by at most one shorter NOP.

The VDUP instruction source register doesn't allow a non-constant lane

5f0d9dbdf4 X86 cost model: Adjust cost for custom lowered vector multiplies
This matters for example in following matrix multiply:

int **mmult(int rows, int cols, int **m1, int **m2, int **m3) {
  int i, j, k, val;
  for (i=0; i<rows; i++) {
    for (j=0; j<cols; j++) {
      val = 0;
      for (k=0; k<cols; k++) {
        val += m1[i][k] * m2[k][j];
      }
      m3[i][j] = val;
    }
  }
  return(m3);
}

Taken from the test-suite benchmark Shootout.

We estimate the cost of the multiply to be 2 while we generate 9 instructions
for it and end up being quite a bit slower than the scalar version (48% on my
machine).

Also, properly differentiate between avx1 and avx2. On avx-1 we still split the
vector into 2 128bits and handle the subvector muls like above with 9
instructions.
Only on avx-2 will we have a cost of 9 for v4i64.

I changed the test case in test/Transforms/LoopVectorize/X86/avx1.ll to use an
add instead of a mul because with a mul we now no longer vectorize. I did
verify that the mul would be indeed more expensive when vectorized with 3
kernels:

for (i ...)
   r += a[i] * 3;
for (i ...)
  m1[i] = m1[i] * 3; // This matches the test case in avx1.ll
and a matrix multiply.

In each case the vectorized version was considerably slower.

This patch eliminates the need to emit a constant move instruction when this

(select (setgt a, Constant), T, F)

The pattern above effectively turns into this:

(conditional-move (setlt a, Constant + 1), F, T)

- ISD::SHL/SRL/SRA must have either both scalar or both vector operands
  but TLI.getShiftAmountTy() so far only return scalar type. As a
  result, backend logic assuming that breaks.
- Rename the original TLI.getShiftAmountTy() to
  TLI.getScalarShiftAmountTy() and re-define TLI.getShiftAmountTy() to
  return target-specificed scalar type or the same vector type as the
  1st operand.
- Fix most TICG logic assuming TLI.getShiftAmountTy() a simple scalar
  type.

fd3417d288 [fast-isel] Add X86FastIsel::FastLowerArguments to handle functions with 6 or
fewer scalar integer (i32 or i64) arguments. It completely eliminates the need
for SDISel for trivial functions.

Also, add the new llc -fast-isel-abort-args option, which is similar to
-fast-isel-abort option, but for formal argument lowering.

4edd84da1b Fix PR14364.
This removes a const_cast hack from PPCRegisterInfo::hasReservedSpillSlot().
The proper place to save the frame index for the CR spill slot is in the
PPCFunctionInfo object, not the PPCRegisterInfo object.

No new test cases, as this just reimplements existing function.  Existing
tests such as test/CodeGen/PowerPC/crsave.ll are sufficient.

700ed80d3d Move the eliminateCallFramePseudoInstr method from TargetRegisterInfo
to TargetFrameLowering, where it belongs. Incidentally, this allows us
to delete some duplicated (and slightly different!) code in TRI.

There are potentially other layering problems that can be cleaned up
as a result, or in a similar manner.

The refactoring was OK'd by Anton Korobeynikov on llvmdev.

Note: this touches the target interfaces, so out-of-tree targets may
be affected.

53b0b0e754 Large code model support for PowerPC.
Large code model is identical to medium code model except that the

use the addis/ld sequence.

The coding changes are straightforward; most of the patch is taken up
with creating variants of the medium model tests for large model.

8389f24a66 getX86SubSuperRegister has a special mode with High=true for i64 which
exists solely to enable it to call itself for i8 with some registers.
The proposed patch simplifies the function somewhat to make the High
bit only meaningful for the i8 mode, which makes sense. No functional
difference (getX86SubSuperRegister is not getting called from anywhere
outside with i64 and High=true).
