Hi all.
I got an automated mail about this GCC regression related to one of my commits.
https://linaro.atlassian.net/browse/GNU-1578
The mail itself mentioned only a testsuite regression. I fixed that. However,
this was also linked in the mail:
https://ci.linaro.org/job/tcwg_bootstrap_build--master-arm-bootstrap_profil…
That looks like a different regression. As far as I can tell, `make
profiledbootstrap` is failing on arm. I have only very limited access to arm
machines. I tried to reproduce this on an Aarch64 machine and didn't succeed.
Could you check that this regression is still present on current trunk and/or
help me reproduce it?
Btw the "Instructions to reproduce the build" link doesn't work for me. I get
"Request is not authorized".
https://git-us.linaro.org/toolchain/ci/interesting-commits.git/plain/gcc/sh…
Thanks,
Filip Kastl
Hi,
For this V2-patch, I got the same "Operation not permitted" errors as
for the V1 one:
https://lists.linaro.org/archives/list/linaro-toolchain@lists.linaro.org/th…
@Adhemerval: have you had a look?
The only non-s390x changes of my patch are in:
elf/Makefile
elf/tst-glibc-hwcaps-cache.script
=> There the libmarkermod6 libraries are added.
As I don't have an arm, I've checked on x86_64, that the testcase
elf/tst-glibc-hwcaps-cache.c contains the libmarkermod6.so files in
glibc-hwcaps/z13-z17 directories by adding a "ldconfig -p" to the test.
Any idea why those "Operation not permitted" regressions hits my patch,
but no others?
Bye,
Stefan

The FAILs are obviously unrelated to the patch which modifies a
different test-case.
But anyway, this a know PR (
https://sourceware.org/bugzilla/show_bug.cgi?id=32445 ).
I've just committed a fix.
Thanks,

Hi,
I have just pushed the following fix on trunk, that fixes a similar issue
for 32bit x86_64.
https://gcc.gnu.org/cgit/gcc/commit/?id=2ca5725e104d432317a44ad45183a4f555d…
Please let me know if the build failure is addressed.
Regards,
Tomasz

Hi,
I've looked at this, and AFAICT this is PR32817 (
https://sourceware.org/bugzilla/show_bug.cgi?id=32817 ).
This is unrelated to the mentioned commit.
Thanks,

Ah, sorry for that. This is due to 'targetm.arm_eabi_unwinder', as per:
gcc/config/arm/arm.cc:#define TARGET_ARM_EABI_UNWINDER true
gcc/config/c6x/c6x.cc:#define TARGET_ARM_EABI_UNWINDER true
..., which for ARM is conditional to '#if ARM_UNWIND_INFO' (defined in
'gcc/config/arm/bpabi.h', used for various GCC configurations), and for
C6x unconditional.
This gets us:
--- target-exceptions-pr118794-1.C.269t.optimized
+++ target-exceptions-pr118794-1.C.270t.optimized
[...]
__attribute__((omp declare target))
void f ()
[...]
gimple_call <__dt_comp , NULL, &c>
- gimple_call <__builtin_eh_pointer, _7, 2>
- gimple_call <__builtin_unwind_resume, NULL, _7>
+ gimple_call <__builtin_cxa_end_cleanup, NULL>
}
[...]
There doesn't appear to be an effective-target keyword for
'targetm.arm_eabi_unwinder' specifically, do we need to add one?
Or, other test cases appear to use effective-target 'arm_eabi' to
disambiguate the two variants; is that the right thing to use here, too?
(..., plus 'tic6x-*-*' in this case?) OK to push the attached
"Adjust 'libgomp.c++/target-exceptions-pr118794-1.C' for 'targetm.arm_eabi_unwinder' [PR118794]"?
(Could Arm/C6x maintainers please test this for me?)

Hi,
I've looked into tests.log.1.xz and there are plenty of "Operation not
permitted" errors. I don't think that this has something to do with my
patch? Can you please check on your side, if there was a change/issue on
the build system?
Bye,
Stefan
