This is a rewrite of the IV simplification algorithm used by
-disable-iv-rewrite. To avoid perturbing the default mode, I
temporarily split the driver and created SimplifyIVUsersNoRewrite. The
idea is to avoid doing opcode/pattern matching inside
IndVarSimplify. SCEV already does it. We want to optimize with the
full generality of SCEV, but optimize def-use chains top down on-demand rather
than rewriting the entire expression bottom-up. This was easy to do
for operations that SCEV can prove are identity function. So we're now
eliminating bitmasks and zero extends this way.

Change how PHINodes store their operands.

Change PHINodes to store simple pointers to their incoming basic blocks,
instead of full-blown Uses.

Note that this loses an optimization in SplitCriticalEdge(), because we
can no longer walk the use list of a BasicBlock to find phi nodes. See
the comment I removed starting "However, the foreach loop is slow for
blocks with lots of predecessors".

Extend replaceAllUsesWith() on a BasicBlock to also update any phi
nodes in the block's successors. This mimics what would have happened
when PHINodes were proper Users of their incoming blocks. (Note that
this only works if OldBB->replaceAllUsesWith(NewBB) is called when
OldBB still has a terminator instruction, so it still has some
successors.)

13 years agoAdd a RegisterTuples class to Target.td and TableGen.
Jakob Stoklund Olesen [Mon, 20 Jun 2011 02:50:54 +0000 (02:50 +0000)]
Add a RegisterTuples class to Target.td and TableGen.

A RegisterTuples instance is used to synthesize super-registers by
zipping together lists of sub-registers. This is useful for generating
pseudo-registers representing register sequence constraints like 'two
consecutive GPRs', or 'an even-odd pair of floating point registers'.

The RegisterTuples def can be used in register set operations when
building register classes. That is the only way of accessing the
synthesized super-registers.

For example, the ARM QQ register class of pseudo-registers could have
been formed like this:

  // Form pairs Q0_Q1, Q2_Q3, ...
  def QQPairs : RegisterTuples<[qsub_0, qsub_1],
                               [(decimate QPR, 2),
                                (decimate (shl QPR, 1), 2)]>;

  def QQ : RegisterClass<..., (add QQPairs)>;

Similarly, pseudo-registers representing '3 consecutive D-regs with
wraparound' look like:

  // Form D0_D1_D2, D1_D2_D3, ..., D30_D31_D0, D31_D0_D1.
  def DSeqTriples : RegisterTuples<[dsub_0, dsub_1, dsub_2],
                                   [(rotl DPR, 0),
                                    (rotl DPR, 1),
                                    (rotl DPR, 2)]>;

TableGen automatically computes aliasing information for the synthesized
registers.

Register tuples are still somewhat experimental. We still need to see
how they interact with MC.

Fix PR10103: Less code for enum type translation.

In cases such as the attached test, where the case value for a switch
destination is used in a phi node that follows the destination, it
might be better to replace that value with the condition value of the
switch, so that more blocks can be folded away with
TryToSimplifyUncondBranchFromEmptyBlock because there are less
conflicts in the phi node.

13 years agoWhen scalar replacement returns a vector type, only accept it if the vector
Cameron Zwarich [Sat, 18 Jun 2011 06:17:51 +0000 (06:17 +0000)]
When scalar replacement returns a vector type, only accept it if the vector
type's bitwidth matches the (allocated) size of the alloca. This severely
pessimizes vector scalar replacement when the only vector type being used is
something like <3 x float> on x86 or ARM whose allocated size matches a
<4 x float>.

I hope to fix some of the flawed assumptions about allocated size throughout
scalar replacement and reenable this in most cases.
