Right. The data-refs analysis fails for the bit assignment, and SLP marks this
statement as not vectorizable and continues with the vectorization of other
statements, which is incorrect because we ignore a possible dependence (as it
happens here).
Instead of just failing for data-refs that can't be analyzed (as in the patch
below), we can check that the statement with the data-ref is either before the
first load or after the last store of the SLP instance, verifying that there is
no data dependence. But this patch is enough to prevent vectorization here and
fix the bug.

I believe it is the problem we run into with Michael on the opensuse conference and we made that module to be last (it is because on my setup sun java does not work and ibm java apparently breaks with current libreoffice). So perhaps this is all needed? It will build fine with LTO (and --without-java), but the resulting binary crashes during startup: terminate called after throwing an instance of 'com::sun::star::container::NoSuchElementException' It throws an exception in: xmlreader::XmlReader::XmlReader(rtl::OUString const) () from image/usr/ure/lib/libxmlreader.so. This happens in xmlreader/source/xmlreader.cxx. I haven't looked deeper yet, but a non LTO build shows no problems at all. The above happened when I configured --with-max-jobs=4 and --with-num-cpus=4. With -with-max-jobs=1 and --with-num-cpus=4 I get a different crash on startup: Hmm, this is very weird. Since max-jobs affects nothing in GCC, it is probably some sort of build machinery problem. I guess it will be needed to debug what really happens here? Honza

(In reply to comment #7)
I reverted the fix on 4.6 branch because it was causing a lot of other trouble
(particularly PR 50295). Therefore, this has to be re-opened.
Hi Martin,
I noticed a new dg directive was added as /* { dg-xfail-run-if { *-*-* }
{ -O2 -O3 -Os } } */. Since then, this case is XPASS for arm-none-eabi
on QEMU for Cortex-M3. Here are the log:
Running
/home/build/work/jenkins-daily-build/src/gcc/gcc/testsuite/gcc.dg/torture/dg-torture.exp
...
XPASS: gcc.dg/torture/pr49886.c -O2 execution test

-finline-functions execution test
XPASS: gcc.dg/torture/pr49886.c -O3 -g execution test
XPASS: gcc.dg/torture/pr49886.c -Os execution test
Do you think the case should fail for arm-none-eabi or not? If not, I think we
may need arm-none-eabi from dg-xfail-run-if.
