I agree, that was more or less my question comment #5 (and the reason why I
didn't sent the patch to gcc-patches)

I think I tried that in first place, and it didn't fix one of the testcases,
but maybe I used a wrong build tree, I'll re-test that.

need some

--- Comment #5 from Yvan Roux  ---
Thinking more about it, I think that the right place to fix it is in the define
of TARGET_HAVE_MOVT or TARGET_USE_MOVT, but I'm a bit confused with these two
macros.

My understanding of their semantic, is that it should be in TARGET_USE_MOVT
(the chip has movt support but we don't want to use it with when
-mword_relocations is used), but if we do so the issue movw/movt will be
generated anyway since arm_movt pattern and "j" contraint uses
TARGET_HAVE_MOVT.

In fact, it seems to me that most of TARGET_HAVE_MOVT should be replaced by
TARGET_USE_MOVT.  Kyrill, Thomas can you educate me ?

My quick understanding is that to prevent LRA generating invalid high/lo_sum
code, arm_valid_symbolic_address_p (introduced at r227129) needs to be
strengthen and check that target_word_relocations is not defined when an addend
is present.

I'll prepare a patch for that shortly.

--- Comment #6 from Yvan Roux  ---
Hi,

I got a small issue when testing the backport into the branch:

g++.dg/lto/pr80287_0.C is not a suitable testcase for GCC 6 branch, since it
uses c++17 class std:any which is not available in GCC 6.  In the first place
this bug was found when building
libstdc++-v3/testsuite/20_util/any/assign/2.cc, but it is not related to
std:any, I found it on my side in ceph package build, and the issue is
exhibited when compiling this reduced testcase with -g:

struct A {
  operator long() {}
} __attribute__((__may_alias__));
struct {
  A ino;
} a;
char b = a.ino;

So, I wonder what is the best way to handle that, adding this new testcase on
trunk as g++.dg/pr80287.C and only backport this one into GCC 6, or avoid
std:any usage into g++.dg/lto/pr80287_0.C ?

Hi Bernd,

with regression introduced at r234768).  I can prepare the backport if you
whish.

Reduced testcase

Hi,

the attached reduced testcase fails with ICE on trunk since r239561.  It was
observed on ARM and AArch64 targets, but might affect targets with
section-anchors enabled.

$ aarch64-linux-gnu-g++ -O2 reduced.C
reduced.C: In function 'void f()':
reduced.C:7:8: internal compiler error: in tree_to_shwi, at tree.c:7313

0x105bffa default_use_anchors_for_symbol_p(rtx_def const*)
.../gcc.git~master/gcc/varasm.c:6810
...

The issue is that tree_to_shwi is called without checking its parameter fits in
a signed HOST_WIDE_INT first.  I've validated the following fix, which does the
checking and avoid using section anchors if it fails, on ARM and AArch64
targets, and will submit it on the list.

No worries, this kind of thing is tricky and deserve board drawings, It's a

Christophe, Kyrill

My understanding of the ARMv8-A Architecture Reference Manual is not the same. 
For me when the vectors have two elements ZIP, UZIP and TRN instruction give
the same result.

for instance if we have:

   + -+--+
Vn |  A1  |  A0  |
   + -+--+
Vm |  B1  |  B0  |
   + -+--+

UZIP1 reads the even-numbered elemenents of Vn (i.e A0), places it in the lower
half of Vd and then do the same with Vm, thus we have:

   + -+--+
Vd |  B0  |  A0  |
   + -+--+

ZIP1 reads the first pair from Vn (which is only A0 is this case) and places it
into the lowest element of Vd and then do same with Vm to get them interleaved,
thus we also have:

   + -+--+
Vd |  B0  |  A0  |
   + -+--+

Maybe the confusion comes from the revision of the manual you looked at, which
doesn't include detailled explanation of these instructions, DDI0487A_k
includes figures.

Kyrill, in the UZP1 figures (C7.2.346) it show that the first unzipped vector
is from Vn ... but maybe I'm the one who misundertand the description ! ;)

--- Comment #3 from Yvan Roux  ---
I'd prefer to cherry-pick it now as it'll not change the current behavior and
simplify the job for the ones (like us ;) who monitor Glibc/GCC trunk
developments (not that cherry-picking the fix is complicated, but the less we
modify the sources we validate the better it is).  But I can also understand
that you prefer to wait Glibc 2.24 before doing it.

--- Comment #1 from Yvan Roux  ---
Hi,

this issue was solved by commit r214797 but is not in 4.9 branch. This code is
executed to check if the target is an ARM cortex M core and this checking is
triggered by the logical_op_short_circuit in the scan-tree-dump-times
directive, commit r214797 avoids trying to compile a testcase if the triplet is
not an ARM one, but having a failure is still valid here (it is an internal
checking which is not reported in testsuite results).

Bug ID: 67127
   Summary: [ARM] Avoiding odd-number ldrd/strd in movdi
introduced a regression on armeb-linux-gnueabihf
   Product: gcc
   Version: 6.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: target
  Assignee: unassigned at gcc dot gnu.org
  Reporter: yroux at gcc dot gnu.org
  Target Milestone: ---

Hi,

Commit r225461 which avoids odd-number ldrd/strd in movdi, and its backport on
gcc-5-branch (r225467) introduced several segfault (stack overflow) in the
testsuite when the compiler is built for big-endian + vfp targets. 

The issue is that the movdi pattern calls gen_lowpart (SImode, operands[0]),
operands being in DImode, but the mode of the register cannot be changed as it
is explained in the macro CANNOT_CHANGE_MODE_CLASS definition:

In big-endian mode, modes greater than word size (i.e. DFmode) are stored in
 VFP registers in little-endian order.  We can't describe that accurately to
 GCC, so avoid taking subregs of such values.

Thus, gen_lowpart_general makes a copy of that register and copy it, which
calls again emit_move_insn and gen_movdi and so on ...

I've a patch under test that prevent doing this when the mode of a register
can't be changed, but the regression discussed in this thread may be back
then...

The latent bug on trunk is now fixed, but the issue is still present in 4.9.2
branch as the patch needs validation on that branch.  I don't plan to validate
it right now, as I don't always have access to the Cubox I validate trunk patch
on and it's really long to do it.

Fix is obvious, there is a typo in insn *thumb2_addsi3_compare0_scratch where
match_operand should be done on operand 1 and not 2 (there is only 2 operands
in this insn).  I'll prepare a testcase as this insn doesn't seem to be
generated really often.

--- Comment #4 from Yvan Roux yroux at gcc dot gnu.org ---
I was about to report the same issue which occurs during the build of videolan
x264 build. Vlad patch fixes the issue on trunk, but with that testcase the
problem is also present in 4.9 branch (it occurs this time in ARM mode on armv6
architecture).

To be backported on 4.9 the rematerialization code as to be removed from the
patch, I'll submit the patch on the mailing list.

command line to reproduce the problem:

cc1 -O3 -marm -march=armv6 -std=c99 a.c

--- Comment #2 from Yvan Roux yroux at gcc dot gnu.org ---
Regression was introduced on trunk and 4.9 branch by fix of PR
rtl-optimization/60969 and then workaround by r211798 (-fuse-caller-save enable
for ARM).

The PR fix changes some IRA cost which makes it choose a IWMMXT_REGS (instead
of a GENERAL_REGS one) for the result of iwmmxt_arm_movdi insn and the
alternatives of this pattern make LRA stuck in a loop.

The -fuse-caller-save patch fixed the issue because it adds IP and CC cloobers
to CALL_INSN_FUNCTION_USAGE, which changes the register allocation (a
GENERAL_REGS is selected this time), but the real issue is in the alternatives
description of iwmmxt_arm_movdi insn.  I've a patch for it that I'll submit.

[Bug libgcc/56846] _Unwind_Backtrace on ARM and noexcept

[yroux at gcc dot gnu.org]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56846

--- Comment #14 from Yvan Roux yroux at gcc dot gnu.org ---

 No I meant FSF 4.8 branch. The bug log only show a commit to trunk and GCC
 4.9 FSF branch.

It's only in trunk (the backport I made was in Linaro 4.9 branch).  For FSF
branches check with the maintainers and/or ping Tony, I don't mind doing it,
but it's maybe better if done by the patch owner.

--- Comment #12 from Yvan Roux yroux at gcc dot gnu.org ---
Hi Thomas,

 Any chance you could backport for 4.8 Yvan? Do you want me to do it? Or are
 the release manager against a 4.8 backport?

Do you mean Linaro 4.8 branch ? if it is the case I'll not be able to do it
before tomorrow (which is our deadline for our 2014.11 source release).
