Begin incorporating target information into BBVectorize.

This is the first of several steps to incorporate information from the new
TargetTransformInfo infrastructure into BBVectorize. Two things are done here:

 1. Target information is used to determine if it is profitable to fuse two
    instructions. This means that the cost of the vector operation must not
    be more expensive than the cost of the two original operations. Pairs that
    are not profitable are no longer considered (because current cost information
    is incomplete, for intrinsics for example, equal-cost pairs are still
    considered).

 2. The 'cost savings' computed for the profitability check are also used to
    rank the DAGs that represent the potential vectorization plans. Specifically,
    for nodes of non-trivial depth, the cost savings is used as the node
    weight.

The next step will be to incorporate the shuffle costs into the DAG weighting;
this will give the edges of the DAG weights as well. Once that is done, when
target information is available, we should be able to dispense with the
depth heuristic.

This patch addresses a PPC64 ELF issue with passing parameters consisting of
structs having size 3, 5, 6, or 7.  Such a struct must be passed and received
as right-justified within its register or memory slot.  The problem is only
present for structs that are passed in registers.

Previously, as part of a patch handling all structs of size less than 8, I
added logic to rotate the incoming register so that the struct was left-
justified prior to storing the whole register.  This was incorrect because
the address of the parameter had already been adjusted earlier to point to
the right-adjusted value in the storage slot.  Essentially I had accidentally
accounted for the right-adjustment twice.

In this patch, I removed the incorrect logic and reorganized the code to make
the flow clearer.

The removal of the rotates changes the expected code generation, so test case
structsinregs.ll has been modified to reflect this.  I also added a new test
case, jaggedstructs.ll, to demonstrate that structs of these sizes can now
be properly received and passed.

I've built and tested the code on powerpc64-unknown-linux-gnu with no new
regressions.  I also ran the GCC compatibility test suite and verified that
earlier problems with these structs are now resolved, with no new regressions.

12 years agoTeach SROA how to split whole-alloca integer loads and stores into
Chandler Carruth [Thu, 25 Oct 2012 04:37:07 +0000 (04:37 +0000)]
Teach SROA how to split whole-alloca integer loads and stores into
smaller integer loads and stores.

The high-level motivation is that the frontend sometimes generates
a single whole-alloca integer load or store during ABI lowering of
splittable allocas. We need to be able to break this apart in order to
see the underlying elements and properly promote them to SSA values. The
hope is that this fixes some performance regressions on x86-32 with the
new SROA pass.

Unfortunately, this causes quite a bit of churn in the test cases, and
bloats some IR that comes out. When we see an alloca that consists soley
of bits and bytes being extracted and re-inserted, we now do some
splitting first, before building widened integer "bucket of bits"
representations. These are always well folded by instcombine however, so
this shouldn't actually result in missed opportunities.

If this splitting of all-integer allocas does cause problems (perhaps
due to smaller SSA values going into the RA), we could potentially go to
some extreme measures to only do this integer splitting trick when there
are non-integer component accesses of an alloca, but discovering this is
quite expensive: it adds yet another complete walk of the recursive use
tree of the alloca.

Either way, I will be watching build bots and LNT bots to see what
fallout there is here. If anyone gets x86-32 numbers before & after this
change, I would be very interested.
