9 years agoThis change fixes three bugs in loop unswitching. This change causes an 81% speed...
Mark Heffernan [Tue, 23 Jun 2015 18:26:50 +0000 (18:26 +0000)]
This change fixes three bugs in loop unswitching. This change causes an 81% speed-up on a benchmark that is based on EigenConvolutionKernel2D from Eigen3, where the lack of loop unswitching blocks hoisting of loads out of a nested loop (see bug 23816 for how loop unswitching and load hoisting are related).

Change 1: Unswitching on trivial conditions should always happen regardless of the computed unswitching cost, as really the cost is zero. While there is code to make that happen, the logic that checks the unswitching cost against a threshold was moved to an earlier point (revision 147935) than the point where trivial unswitching is detected, so trivial unswitching is currently blocked by the cost threshold. This change fixes that.

Change 2: Before revision 147935 (from 2012-01-11), the threshold parameter was a per-loop threshold. So an unswitching happened only if the cost of the unswitching was less than the threshold. In an indirect way (and I believe unintentionally), the logic for this since then has been that the threshold is an over-all budget across all loops for all loop unswitching done by a given LoopUnswitch loop pass object. So if an unswitching with cost 100 happens in one function, that in effect reduces the threshold from 100 to 0 for the loops even in another function. This persists for the lifetime of that loop pass object. This makes no difference for most small examples but it is important for large examples. This revision fixes that.

Change 3: The cost is currently calculated as std::min(NumInstructions, 5 * NumBlocks). So a loop with 2 blocks and a million instructions will have an unswitching cost of 10. I changed this to just NumInstructions, as it were before revision 147935, though I'm open to e.g. instead replacing std::min with std::max.

I've tried to make the change minimally invasive while staying with what I think was the original intent of the code.

Sanjay Patel [Tue, 23 Jun 2015 00:39:40 +0000 (00:39 +0000)]
[x86] generalize reassociation optimization in machine combiner to 2 instructions

Currently ( D10321, http://reviews.llvm.org/rL239486 ), we can use the machine combiner pass
to reassociate the following sequence to reduce the critical path:

A = ? op ?
B = A op X
C = B op Y
-->
A = ? op ?
B = X op Y
C = A op B

'op' is currently limited to x86 AVX scalar FP adds (with fast-math on), but in theory, it could
be any associative math/logic op (see TODO in code comment).

This patch generalizes the pattern match to ignore the instruction that defines 'A'. So instead of
a sequence of 3 adds, we now only need to find 2 dependent adds and decide if it's worth
reassociating them.

This generalization has a compile-time cost because we can now match more instruction sequences
and we rely more heavily on the machine combiner to discard sequences where reassociation doesn't
improve the critical path.

For example, in the new test case:

A = M div N
B = A add X
C = B add Y

We'll match 2 reassociation patterns, but this transform doesn't reduce the critical path:

A = M div N
B = A add Y
C = B add X

We need the combiner to reject that pattern but select this:

A = M div N
B = X add Y
C = B add A

9 years ago[X86] Teach load folding to accept scalar _Int users of MOVSS/MOVSD.
Ahmed Bougacha [Mon, 22 Jun 2015 20:51:51 +0000 (20:51 +0000)]
[X86] Teach load folding to accept scalar _Int users of MOVSS/MOVSD.

The _Int instructions are special, in that they operate on the full
VR128 instead of FR32.  The load folding then looks at MOVSS, at the
user, and bails out when it sees a size mismatch.

What we really know is that the rm_Int instructions don't load the
higher lanes, so folding is fine.

This happens for the straightforward intrinsic code, e.g.:

    _mm_add_ss(a, _mm_load_ss(p));

Fixes PR23349.
