Hi Andrew,
The movsi_ne variants are in a wrong order, leading to wrong
computation of the internal attribute "cond". Hence, to errors when
outputting annul-true or annul-false instructions. Testcase added.
The patch needs to go for trunk and gcc9 branch.
OK to apply?

Hello,
I've only noticed a couple typos, and one minor remark. From my
perspective it's okay, but you still need the okay of a proper reviewer,
for which you might want to state the testing/regression state of this
patch relative to trunk. The remarks follow:
On Tue, 22 Oct 2019, Feng Xue
The following fixes an ICE when vectorizable_reduction asks for
the optab for a shift but passes optab_default. Simply pass
optab_vector since that's what it code-generates later. As
optimization if its own code-generator fails try the regular
one.

Hi All,
Glibc has recently introduced changed to the mode field in ipc_perm
in commit 2f959dfe849e0646e27403f2e4091536496ac0f0. For Arm this
means that the mode field no longer has the same size.
This causes an assert failure against libsanitizer's internal copy
of ipc_perm. Since this change

Hi Andrew,
There are cases when an pic address gets complicated, and it needs to
be resolved via force_reg function found in
prepare_move_operands. When this happens, we need to disambiguate the
pic address and re-legitimize it. Testcase added as well.
