9 years ago[AArch64] Use intermediate step for concat_vectors of illegal truncs.

[AArch64] Use intermediate step for concat_vectors of illegal truncs.

Optimize concat_vectors of truncated vectors, where the intermediate
type is illegal, to avoid said illegality,  e.g.,
  (v4i16 (concat_vectors (v2i16 (truncate (v2i64))),
                         (v2i16 (truncate (v2i64)))))
->
  (v4i16 (truncate (v4i32 (concat_vectors (v2i32 (truncate (v2i64))),
                                          (v2i32 (truncate (v2i64)))))))

This isn't really target-specific, and, as such, would best go in the
DAGCombiner.  However, ISD::TRUNCATE legality isn't keyed on both input
and result type, so we might generate worse code when we don't know
better.  On AArch64 we know it's fine for v2i64->v4i16 and v4i32->v8i8.

Michael Gottesman [Mon, 16 Mar 2015 07:02:36 +0000 (07:02 +0000)]
[objc-arc] Make the ARC optimizer more conservative by forcing it to be non-safe in both direction, but mitigate the problem by noting that we just care if there was a further use.

The problem here is the infamous one direction known safe. I was
hesitant to turn it off before b/c of the potential for regressions
without an actual bug from users hitting the problem. This is that bug ;
).

The main performance impact of having known safe in both directions is
that often times it is very difficult to find two releases without a use
in-between them since we are so conservative with determining potential
uses. The one direction known safe gets around that problem by taking
advantage of many situations where we have two retains in a row,
allowing us to avoid that problem. That being said, the one direction
known safe is unsafe. Consider the following situation:

retain(x)
retain(x)
call(x)
call(x)
release(x)

Then we know the following about the reference count of x:

// rc(x) == N (for some N).
retain(x)
// rc(x) == N+1
retain(x)
// rc(x) == N+2
call A(x)
call B(x)
// rc(x) >= 1 (since we can not release a deallocated pointer).
release(x)
// rc(x) >= 0

That is all the information that we can know statically. That means that
we know that A(x), B(x) together can release (x) at most N+1 times. Lets
say that we remove the inner retain, release pair.

// rc(x) == N (for some N).
retain(x)
// rc(x) == N+1
call A(x)
call B(x)
// rc(x) >= 1
release(x)
// rc(x) >= 0

We knew before that A(x), B(x) could release x up to N+1 times meaning
that rc(x) may be zero at the release(x). That is not safe. On the other
hand, consider the following situation where we have a must use of
release(x) that x must be kept alive for after the release(x)**. Then we
know that:

// rc(x) == N (for some N).
retain(x)
// rc(x) == N+1
retain(x)
// rc(x) == N+2
call A(x)
call B(x)
// rc(x) >= 2 (since we know that we are going to release x and that that release can not be the last use of x).
release(x)
// rc(x) >= 1 (since we can not deallocate the pointer since we have a must use after x).
…
// rc(x) >= 1
use(x)

Thus we know that statically the calls to A(x), B(x) can together only
release rc(x) N times. Thus if we remove the inner retain, release pair:

// rc(x) == N (for some N).
retain(x)
// rc(x) == N+1
call A(x)
call B(x)
// rc(x) >= 1
…
// rc(x) >= 1
use(x)

We are still safe unless in the final â€¦ there are unbalanced retains,
releases which would have caused the program to blow up anyways even
before optimization occurred. The simplest form of must use is an
additional release that has not been paired up with any retain (if we
had paired the release with a retain and removed it we would not have
the additional use). This fits nicely into the ARC framework since
basically what you do is say that given any nested releases regardless
of what is in between, the inner release is known safe. This enables us to get
back the lost performance.

InstrProf: Do a better job of reading coverage mapping data.

This code was casting regions of a memory buffer to a couple of
different structs. This is wrong in a few ways:

1. It breaks aliasing rules.
2. If the buffer isn't aligned, it hits undefined behaviour.
3. It completely ignores endianness differences.
4. The structs being defined for this aren't specifying their padding
   properly, so this doesn't even represent the data properly on some

This commit is mostly NFC, except that it fixes reading coverage for
32 bit binaries as a side effect of getting rid of the mispadded
structs. I've included a test for that.

endianness properly in a followup commit.

[dsymutil] Add support for linking line tables.

dsymutil behavior. A much simpler approach (described in the numerous
FIXMEs that I put in there) gives the right output for the vast

need to be investigated: they seem to correctly handle debug info that
is in the input, but that info looks suspicious in the first place.

Anyway, the current code needs to handle this, but I plan to revisit it
as soon as the big round of validation against the classic dsymutil is
over.
