StructurizeCFG: Use a reverse post-order traversal

We were previously doing a post-order traversal and operating on the
list in reverse, however this would occasionaly cause backedges for
loops to be visited before some of the other blocks in the loop.

We know use a reverse post-order traversal, which avoids this issue.

The reverse post-order traversal is not completely ideal, so we need
to manually fixup the list to ensure that inner loop backedges are
visited before outer loop backedges.

Philip Reames [Wed, 4 Feb 2015 00:37:33 +0000 (00:37 +0000)]
Add a pass for inserting safepoints into (nearly) arbitrary IR

This pass is responsible for figuring out where to place call safepoints and safepoint polls. It doesn't actually make the relocations explicit; that's the job of the RewriteStatepointsForGC pass (http://reviews.llvm.org/D6975).

Note that this code is not yet finalized.  Its moving in tree for incremental development, but further cleanup is needed and will happen over the next few days.  It is not yet part of the standard pass order.

Planned changes in the near future:
 - I plan on restructuring the statepoint rewrite to use the functions add to the IRBuilder a while back.
 - In the current pass, the function "gc.safepoint_poll" is treated specially but is not an intrinsic. I plan to make identifying the poll function a property of the GCStrategy at some point in the near future.
 - As follow on patches, I will be separating a collection of test cases we have out of tree and submitting them upstream.
 - It's not explicit in the code, but these two patches are introducing a new state for a statepoint which looks a lot like a patchpoint. There's no a transient form which doesn't yet have the relocations explicitly represented, but does prevent reordering of memory operations. Once this is in, I need to update actually make this explicit by reserving the 'unused' argument of the statepoint as a flag, updating the docs, and making the code explicitly check for such a thing. This wasn't really planned, but once I split the two passes - which was done for other reasons - the intermediate state fell out. Just reminds us once again that we need to merge statepoints and patchpoints at some point in the not that distant future.

Future directions planned:
 - Identifying more cases where a backedge safepoint isn't required to ensure timely execution of a safepoint poll.
 - Tweaking the insertion process to generate easier to optimize IR. (For example, investigating making SplitBackedge) the default.
 - Adding opt-in flags for a GCStrategy to use this pass. Once done, add this pass to the actual pass ordering.

    PPCISelLowering.cpp: Make CTPOP legal for vector types.

data types.  When adding the v2i64 type to the Vector Register set, I

9 years agoAdd straight-line strength reduction to LLVM
Jingyue Wu [Tue, 3 Feb 2015 19:37:06 +0000 (19:37 +0000)]
Add straight-line strength reduction to LLVM

Summary:
Straight-line strength reduction (SLSR) is implemented in GCC but not yet in
LLVM. It has proven to effectively simplify statements derived from an unrolled
loop, and can potentially benefit many other cases too. For example,

LLVM unrolls

  #pragma unroll
  foo (int i = 0; i < 3; ++i) {
    sum += foo((b + i) * s);
  }

into

  sum += foo(b * s);
  sum += foo((b + 1) * s);
  sum += foo((b + 2) * s);

However, no optimizations yet reduce the internal redundancy of the three
expressions:

  b * s
  (b + 1) * s
  (b + 2) * s

With SLSR, LLVM can optimize these three expressions into:

  t1 = b * s
  t2 = t1 + s
  t3 = t2 + s

This commit is only an initial step towards implementing a series of such
optimizations. I will implement more (see TODO in the file commentary) in the
near future. This optimization is enabled for the NVPTX backend for now.
However, I am more than happy to push it to the standard optimization pipeline
after more thorough performance tests.

from varying offsets of a base pointer. These loads did not match the existing

A happy side effect of doing this optimization earlier is that we can now fold
the load into a math op where possible; this is shown in some of the updated

one example is StackProtector pass. We will get assertion failure when running

lto_api_version is added so ld64 can check for runtime-availability of the new
