[PowerPC] Generate little-endian object files

As a first step towards real little-endian code generation, this patch
changes the PowerPC MC layer to actually generate little-endian object
files.  This involves passing the little-endian flag through the various
layers, including down to createELFObjectWriter so we actually get basic
little-endian ELF objects, emitting instructions in little-endian order,
and handling fixups and relocations as appropriate for little-endian.

The bulk of the patch is to update most test cases in test/MC/PowerPC
to verify both big- and little-endian encodings.  (The only test cases
*not* updated are those that create actual big-endian ABI code, like
the TLS tests.)

Note that while the object files are now little-endian, the generated
code itself is not yet updated, in particular, it still does not adhere
to the ELFv2 ABI.

[mips] Implement shorthand add / sub forms for MIPS.

Summary:
- If only two registers are passed to a three-register operation, then the
  first argument is both source and destination register.

- If a non-register is passed as the last argument, generate the immediate
  version of the instruction.

Also mark DADD commutative and add scheduling information (to the generic
scheduler), and implement DSUB.

7 years ago[PowerPC] Update comment re: VSX copy-instruction selection
Hal Finkel [Mon, 24 Mar 2014 09:36:36 +0000 (09:36 +0000)]
[PowerPC] Update comment re: VSX copy-instruction selection

I've done some experimentation with this, and it looks like using the
lower-latency (but lower throughput) copy instruction is essentially always the
right thing to do.

My assumption is that, in order to be relatively sure that the higher-latency
copy will increase throughput, we'd want to have it unlikely to be in-flight
with its use. On the P7, the global completion table (GCT) can hold a maximum
of 120 instructions, shared among all active threads (up to 4), giving 30
instructions per thread.  So specifically, I'd require at least that many
instructions between the copy and the use before the high-latency variant is
used.

Trying this, however, over the entire test suite resulted in zero cases where
the high-latency form would be preferable. This may be a consequence of the
fact that the scheduler views copies as free, and so they tend to end up close
to their uses. For this experiment I created a function:

  unsigned chooseVSXCopy(MachineBasicBlock &MBB,
                         MachineBasicBlock::iterator I,
                         unsigned DestReg, unsigned SrcReg,
                         unsigned StartDist = 1,
                         unsigned Depth = 3) const;

with an implementation like:

  if (!Depth)
    return PPC::XXLOR;

  const unsigned MaxDist = 30;
  unsigned Dist = StartDist;
  for (auto J = I, JE = MBB.end(); J != JE && Dist <= MaxDist; ++J) {
    if (J->isTransient() && !J->isCopy())
      continue;

    if (J->isCall() || J->isReturn() || J->readsRegister(DestReg, TRI))
      return PPC::XXLOR;

    ++Dist;
  }

  // We've exceeded the required distance for the high-latency form, use it.
  if (Dist > MaxDist)
    return PPC::XVCPSGNDP;

  // If this is only an exit block, use the low-latency form.
  if (MBB.succ_empty())
    return PPC::XXLOR;

  // We've reached the end of the block, check the successor blocks (up to some
  // depth), and use the high-latency form if that is okay with all successors.
  for (auto J = MBB.succ_begin(), JE = MBB.succ_end(); J != JE; ++J) {
    if (chooseVSXCopy(**J, (*J)->begin(), DestReg, SrcReg,
                      Dist, --Depth) == PPC::XXLOR)
      return PPC::XXLOR;
  }

  // All of our successor blocks seem okay with the high-latency variant, so
  // we'll use it.
  return PPC::XVCPSGNDP;

and then changed the copy opcode selection from:
    Opc = PPC::XXLOR;
to:
    Opc = chooseVSXCopy(MBB, std::next(I), DestReg, SrcReg);

In conclusion, I'm removing the FIXME from the comment, because I believe that
there is, at least absent other examples, nothing to fix.

In the case of a switch statement it is possible that a following PHI node may
have more than one such pair per incoming basic block. E.g.:
%0 = phi i64 [ 123456, %case2 ], [ 654321, %Entry ], [ 654321, %Entry ]
This is valid and the verfier doesn't complain, because both values are the
same.

Constant hoisting materializes the constant for each operand separately and the
value is still the same, but the variable names have changed. As a result the
verfier can't recognize anymore that they are the same value and complains.

This fix adds special update code for PHI node in constant hoisting to prevent
this corner case.
