It's now available under "F08/0048" at
ftp://ftp.nag.co.uk/sc22wg5/N1951-N2000/N1959.txt - published as Corrigendum 2
to Fortran 2008.

No - the code is valid. The added wording was "an element of a simply
contiguous array" - and the example from comment 0 ("call sub (x(10))") is the
latter.

[Bug tree-optimization/68673] Handle __builtin_GOMP_task optimally in ipa-pta

[vries at gcc dot gnu.org]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68673

--- Comment #7 from vries at gcc dot gnu.org ---
The constraints generated for the GOMP_task call look ok to me:
...
_Z2f3v._omp_cpyfn.1.arg0 = _CPFN_TMP.0+64
_Z2f3v._omp_cpyfn.1.arg1 = &.omp_data_o.2.0+64

_Z2f3v._omp_fn.0.arg0 = _CPFN_TMP.0+64
...

And we seem to be able to conclude that the loads and stores in
_Z2f3v._omp_fn.0 point to a, b and c:
...
_12 = { ESCAPED NONLOCAL a }
_14 = { ESCAPED NONLOCAL b }
_16 = { ESCAPED NONLOCAL c }
...
But AFAIU, the escaped/nonlocal bit causes the optimization to fail.

I'm not sure yet if the escaped/nonlocal bit is:
- too conservative, or
- actually necessary (due to either GOMP_task, or the testcase).

[Bug ipa/64812] [4.9 regression] x86 LibreOffice Build failure: undefined reference to acquire

actual code in LibreOffice *did* link with the implementation of the class -
there were 2 libraries involved, "toolkit" contained the implementation of
ListenerMultiplexerBase and "svxcore" linked against it;
ListenerMultiplexerBase has __attribute__ ((visibility("default"))) so its
member functions should be exported.

the member functions in question (acquire and release) are inline, and i was
assuming that it's ok then that they are not exported from the library
containing the impl. of the class, but if you say that linking needs to happen
anyway then maybe the bug is that the inline functions are not exported from
the "toolkit" library by GCC.

I don't think it's necessary to change anything.

[Bug tree-optimization/68694] New: SLP loads should be permuted until supported if possible

[rguenth at gcc dot gnu.org]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68694

Bug ID: 68694
   Summary: SLP loads should be permuted until supported if
possible
   Product: gcc
   Version: 6.0
Status: UNCONFIRMED
  Keywords: missed-optimization
  Severity: enhancement
  Priority: P3
 Component: tree-optimization
  Assignee: unassigned at gcc dot gnu.org
  Reporter: rguenth at gcc dot gnu.org
Blocks: 53947
  Target Milestone: ---

gcc.dg/vect/pr45752.c FAILs with --param=tree-reassoc-width=2 because the
association lets us arrive with a load permutation we don't support.  With
this testcase it's possible to shuffle the SLP tree (without making it invalid)
making the load permutation supported.

--- Comment #1 from Richard Biener  ---
Huh.  It somehow arrives at

gcc/testsuite/gcc.dg/vect/pr45752.c:45:3: note: Load permutation 4 4 4 4 4 0 0
0 3 3 1 1 1 2 2 3 3 3 0 0 2 2 2 1 1

instead of the desired

Load permutation 2 2 2 2 2 3 3 3 3 3 0 0 0 0 0 1 1 1 1 1 4 4 4 4 4

hmm, it's probably a bit of luck which association you get for the addition
chain.  tree-reasssoc-width may play a role here - yep, with --param
tree-reassoc-width=2 it fails on x86_64 as well.

This is a missed optimization opportunity - shuffling the SLP tree (where
possible) to make load permutations supported.

In this case we can also amend the testcase to use --param tree-reassoc-width=1
