[LV] Preserve LoopInfo when store predication is used

This was a latent bug that got exposed by the change to add LoopSimplify
as a dependence to LoopLoadElimination.  Since LoopInfo was corrupted
after LV, LoopSimplify mis-compiled nbench in the test-suite (more
details in the PR).

The problem was that when we create the blocks for predicated stores we
didn't add those to any loops.

The original testcase for store predication provides coverage for this

DenseMap: make .resize() do the intuitive thing

In some places, like InstCombine, we resize a DenseMap to fit the elements
we intend to put in it, then insert those elements (to avoid continual
reallocations as it grows). But .resize(foo) doesn't actually do what
people think; it resizes to foo buckets (which is really an
implementation detail the user of DenseMap probably shouldn't care about),
not the space required to fit foo elements. DenseMap grows if 3/4 of its
buckets are full, so this actually causes one forced reallocation every
time instead of avoiding a reallocation.

This patch makes .resize(foo) do the intuitive thing: it grows to the size
necessary to fit foo elements without new allocations.

Also include a test to verify that .resize() actually does what we think it
does.

Justin Lebar [Mon, 14 Mar 2016 23:15:34 +0000 (23:15 +0000)]
[LoopUnroll] Respect the convergent attribute.

Summary:
Specifically, when we perform runtime loop unrolling of a loop that
contains a convergent op, we can only unroll k times, where k divides
the loop trip multiple.

Without this change, we'll happily unroll e.g. the following loop

  for (int i = 0; i < N; ++i) {
    if (i == 0) convergent_op();
    foo();
  }

into

  int i = 0;
  if (N % 2 == 1) {
    convergent_op();
    foo();
    ++i;
  }
  for (; i < N - 1; i += 2) {
    if (i == 0) convergent_op();
    foo();
    foo();
  }.

This is unsafe, because we've just added a control-flow dependency to
the convergent op in the prelude.

In general, runtime unrolling loops that contain convergent ops is safe
only if we don't have emit a prelude, which occurs when the unroll count
divides the trip multiple.

This doesn't accomplish anything on its own. It's the first step towards preserving

The next step would be to make sure we're propagating the info in all of the other
places where we create selects (SimplifyCFG, InstCombine, etc). I don't think there's
an easy fix to make this happen; we have to look at each transform individually to
determine how to correctly propagate the weights.

Along with that step, we need to then use the weights when making subsequent transform
decisions such as discussed in http://reviews.llvm.org/D16836.

The inliner test is independent but closely related. It verifies that metadata is

8 years ago[SpillPlacement] Fix a quadratic behavior in spill placement.
Quentin Colombet [Mon, 14 Mar 2016 18:21:25 +0000 (18:21 +0000)]
[SpillPlacement] Fix a quadratic behavior in spill placement.

The bad behavior happens when we have a function with a long linear chain of
basic blocks, and have a live range spanning most of this chain, but with very
few uses.
Let say we have only 2 uses.
The Hopfield network is only seeded with two active blocks where the uses are,
and each iteration of the outer loop in `RAGreedy::growRegion()` only adds two
new nodes to the network due to the completely linear shape of the CFG.
Meanwhile, `SpillPlacer->iterate()` visits the whole set of discovered nodes,
which adds up to a quadratic algorithm.

This is an historical accident effect from r129188.

When the Hopfield network is expanding, most of the action is happening on the
frontier where new nodes are being added. The internal nodes in the network are
not likely to be flip-flopping much, or they will at least settle down very
quickly. This means that while `SpillPlacer->iterate()` is recomputing all the
nodes in the network, it is probably only the two frontier nodes that are
changing their output.

Instead of recomputing the whole network on each iteration, we can maintain a
SparseSet of nodes that need to be updated:

- `SpillPlacement::activate()` adds the node to the todo list.
- When a node changes value (i.e., `update()` returns true), its neighbors are
  added to the todo list.
- `SpillPlacement::iterate()` only updates the nodes in the list.

The result of Hopfield iterations is not necessarily exact. It should converge
to a local minimum, but there is no guarantee that it will find a global
minimum. It is possible that updating nodes in a different order will cause us
to switch to a different local minimum. In other words, this is not NFC, but
although I saw a few runtime improvements and regressions when I benchmarked
this change, those were side effects and actually the performance change is in
the noise as expected.

Huge thanks to Jakob Stoklund Olesen <stoklund@2pi.dk> for his feedbacks,
guidance and time for the review.

[mips] MIPS32R6 compact branch support

Summary:
MIPSR6 introduces a class of branches called compact branches. Unlike the
traditional MIPS branches which have a delay slot, compact branches do not
have a delay slot. The instruction following the compact branch is only
executed if the branch is not taken and must not be a branch.

It works by generating compact branches for MIPS32R6 when the delay slot
filler cannot fill a delay slot. Then, inspecting the generated code for
forbidden slot hazards (a compact branch with an adjacent branch or other
CTI) and inserting nops to clear this hazard.

8 years ago[SystemZ] Avoid LER on z13 due to partial register dependencies
Ulrich Weigand [Mon, 14 Mar 2016 13:50:03 +0000 (13:50 +0000)]
[SystemZ] Avoid LER on z13 due to partial register dependencies

On the z13, it turns out to be more efficient to access a full
floating-point register than just the upper half (as done e.g.
by the LE and LER instructions).

Current code already takes this into account when loading from
memory by using the LDE instruction in place of LE.  However,
we still generate LER, which shows the same performance issues
as LE in certain circumstances.

This patch changes the back-end to emit LDR instead of LER to
implement FP32 register-to-register copies on z13.

[mips] Simplify ordering of range checked immediate classes.

Summary:
With the addition of checks to ensure that operands have a strict ordering
it has become tricky to manage the order in the way I originally intended.

This patch linearizes the ordering which simplifies the implementation but
requires an order that is arbitrary in places. Here are some examples:
* uimm4 < uimm5 < uimm6
* simm4 < uimm4 < simm5 < uimm5
* uimm5 < uimm5_plus1 (1..32) < uimm5_plus32 (32..63) < uimm6
  The term 'superset' starts to break down here since the *_plus* classes
  are not true supersets of uimm5 (but they are still subsets of uimm6).
* uimm5 < uimm5_64, and uimm5 < vsplat_uimm5
  This is entirely arbitrary. We need an ordering and what we pick is
  unimportant since only one is possible for a given mnemonic.

[CodeView] Truncate display names

Fundamentally, the length of a variable or function name is bound by the
maximum size of a record: 0xffff.  However, the name doesn't live in a
vacuum; other data is associated with the name, lowering the bound
further.

We would naively attempt to emit the name, causing us to assert because
the record would no-longer fit in 16-bits.  Instead, truncate the name
but preserve as much as we can.

While I have tested this locally, I've decided to not commit it due to
the test's size.

N.B.  While this behavior is undesirable, it is better than MSVC's
behavior.  They seem to truncate to ~4000 characters.
