Duncan P. N. Exon Smith [Mon, 16 Feb 2015 19:18:01 +0000 (19:18 +0000)]
Bitcode: Fix major regression: large files w/ debug info

The metadata/value split introduced a major regression reading large
bitcode files that contain debug info (or other cyclic (non-self
reference) metadata graphs).  For the first time in a while, I dropped
from libLTO.dylib down to `llvm-lto` with a non-trivial bitcode file
(~350MB), and I hit this when reading the result of ld64's `-save-temps`
in `llvm-lto`.

Here's pseudo-code for what was going on:

    read-main-metadata-block:
      for each md:
        if has-fwd-ref: // Only true for cyclic graphs.
          any-fwd-refs <- true
      if any-fwd-refs:
        foreach md:
          resolve-cycles(md) // Handle cycles.

    foreach function:
      read-function-metadata-block: // Such as !alias, !loop
        if any-fwd-refs:
          foreach md: // (all metadata, not just this block)
            resolve-cycles(md) // A no-op, but the loop is expensive!!

This commit resets the `AnyFwdRefs` flag to `false`.  This on its own
was enough to change my Release+Asserts `llvm-lto` time for reading this
bitcode from over 20 minutes (I gave up on it) to 20 seconds.  I've gone
further by tracking the min/max metadata forward-references in a
metadata block.  This protects against a schema that has lots of
functions that each reference their own metadata cycle.

Unfortunately, this regression is in the 3.6 branch as well.

9 years ago[x86] Teach the 128-bit vector shuffle lowering routines to take
Chandler Carruth [Mon, 16 Feb 2015 01:52:02 +0000 (01:52 +0000)]
[x86] Teach the 128-bit vector shuffle lowering routines to take
advantage of the existence of a reasonable blend instruction.

The 256-bit vector shuffle lowering has leveraged the general technique
of decomposed shuffles and blends for quite some time, but this never
made it back into the 128-bit code, and there are a large number of
patterns where this is substantially better. For example, this removes
almost all domain crossing in vector shuffles that involve some blend
and some permutation with SSE4.1 and later. See the massive reduction
in 'shufps' for integer test cases in this commit.

This isn't perfect yet for a few reasons:

1) The v8i16 shuffle lowering continues to plague me. We don't always
   form an unpack-based blend when that would be better. But the wins
   pretty drastically outstrip the losses here.
2) The v16i8 shuffle lowering is just a disaster here. I never went and
   implemented blend support here for some terrible reason. I'll do
   that next probably. I've not updated it for now.

More variations on this technique are coming as well -- we don't
shuffle-into-unpack or shuffle-into-palignr, both of which would also be
profitable.

Note that some test cases grow significantly in the number of
instructions, but I expect to actually be faster. We use
pshufd+pshufd+blendw instead of a single shufps, but the pshufd's are
very likely to pipeline well (two ports on most modern intel chips) and
the blend is a *very* fast instruction. The domain switch penalty will
essentially always be more than a blend instruction, which is the only
increase in tree height.

9 years ago[x86] When splitting 256-bit vectors into 128-bit vectors, don't extract
Chandler Carruth [Sun, 15 Feb 2015 10:12:02 +0000 (10:12 +0000)]
[x86] When splitting 256-bit vectors into 128-bit vectors, don't extract
subvectors from buildvectors. That doesn't really make any sense and it
breaks all of the down-stream matching of buildvectors to cleverly lower
shuffles.

With this, we now get the shift-based lowering of 256-bit vector
shuffles with AVX1 when we split them into 128-bit vectors. We also do
much better on the zero-extension patterns, although there remains quite
a bit of room for improvement here.
