With Microblaze Gcc version < 8.x build hangs on compiling last files
before linking.
This is due to bug 71124:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71124
Bug shows up building sqlite with optimization but not when building
with -O0.

If BR2_TOOLCHAIN_HAS_GCC_BUG_71124=y force using -O0 passing it to
SQLITE_CFLAGS.

libnss gcc bug 85862 has been worked around and that caused build
failure on Microblaze.

Remove 'depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85862' and 'depends on
!BR2_microblaze' from Config.in allowing this package to build.

'depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85862' is listed because libnss
was affected by that bug in latest Qt5, but now that bug has been worked
around.

So remove 'depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85862' and allow
building latest Qt5 by removing also '|| BR2_PACKAGE_QT5_VERSION_5_6'.

Commit:
https://git.buildroot.net/buildroot/commit/?id=bad25aff36b70b55b34ea4580b45f657385ae9ac
removed sourcery toolchain already deprecated in 2014 causing build
failure. It was based on Gcc 4.6.2 and Buildroot doesn't use this
anymore.

Remove check against BR2_microblaze and BR2_sh2a.

Is there any evidence that bug 71124 and 85180 are different ?

When there is an infinite loop when building a package on Microblaze,
how do you know if it's caused by gcc bug 71124 or gcc bug 85180 ?

Best regards,

Thomas

Actually not, I only based it on comments present inside Config.in, but 
almost probably they are the same.
Maybe is it better to fuse them into 85180?

Also, do i need to send these for next branch?
Because these patches don't fix bug, they only allow to build packages 
that before were not available.

Best regards

I would suggest so, and perhaps we can mark 71124 as a duplicate of
85180 on the gcc bug tracker as well.

> Also, do i need to send these for next branch?

As said on IRC: just base your patches in master. I think it's material
from master, and if Peter/Arnout disagree, we will apply on next: there
won't be much conflicts anyway, and if there's any, it will be a
trivial conflict.

Best regards,

Thomas

Ok, I'm going to mark as duplicate on gcc bug tracker and fuse 71124 
into 85180.

Following 'Fix GCC BUG 85180 per-package' patchset:
https://patchwork.ozlabs.org/project/buildroot/list/?series=109024
this patchset makes possible to build packages affected by GCC bugs 85180
and 85862.

V1->V2:
* merge gcc bug 71124 into 85180 since they are the same
  71124 has been marked as duplicate of 85180.
* removed patch 0001 where BUG_71124 was added since it's useless now

Giulio Benetti (7):
  package/sqlite: fix BUG_85180 build timeout
  package/ffmpeg: re-enable package if BUG_85180 is present
  package/assimp: re-enable package if BR2_microblaze is enabled
  package/libnss: re-enable package if BUG_85862 is present
  package/ecryptfs-utils: allow building with GCC_BUG_85862 and on
    Microblaze
  package/qt5webengine: re-enable building if BUG_85682=y on latest Qt5
  package/flashbench: remove old check if BR2_microblaze & BR2_sh2a

With Microblaze Gcc version < 8.x build hangs on compiling last files
before linking.
This is due to bug 85180:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180
Bug shows up building sqlite with optimization but not when building
with -O0.

If BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y force using -O0 passing it to
SQLITE_CFLAGS.

I cannot reproduce this timeout, and you don't have any autobuilder
failure. Could you provide a configuration that exhibits the failure ?

Thanks!

Sure, the problems comes out building libnss with gcc4.9/5/6/7.
Here is pastebin of my savedefconfig:
https://pastebin.com/wmR8Dme3

I use external toolchains, but they are BR toolchains.
The commit log is not precise, need to improve it.

Best regards

I still don't understand. You're mentioning libnss, but your defconfig
does not have libnss enabled. Am I missing something ?

Oh sorry, I use that defconfig and then I give:
"make libnss"

that causes 85180.

But then what is the relationship with sqlite ? Your original patch,
which I'm replying to, is about fixing a build timeout in sqlite.

Ah yes, sqlite is a dependency of libnss.
And now I've found that it happens only with Gcc 4.9
I've been confused because when compiling sqlite3.c file it takes a very 
long time with Gcc 5/6/7/8/9 and I thought they hanged.
Instead it hangs only with Gcc 4.9, so it's a different Gcc bug, not 85180.
Need to check in gcc bugzilla, otherwise I should submit a new bug.

Can you try to build and check it hangs with gcc 4.9 and building sqlite 
during compiling sqlite3.c ?
This is to double check.

Thank you
Best regards

It's a Gcc 4.9 only bug that I need to submit to gcc bugzilla.

Atharva built it and found it hangs while compiling sqlite3.c as me.

So, after submitting Gcc bug I'm going to add that bug to toolchain's 
Config.in and setting -O0 in sqlite.mk if that bug=y

Then I rewrite commit log and resubmit, but at this point this is not 
part of this patchset.

Right?

 There's not much point to submit a bug for GCC 4.9, which is no longer
maintained...

Ah, I didn't know it's maintained anymore.
So in this case I can base the rule for using -O0 on 
BR2_TOOLCHAIN_GCC_AT_LEAST_5 and comment on top of it.
At the moment sqlite is the only package suffering from this.

Thank you
Kind regards

 You mean, without introducing a _GCC_HAS_BUG_ option, right? Sounds good to me.

Yes. I hope there won't be other packages affected by this, but since 
4.9 is no longer maintained I don't see other way, excect adding 
internal special _GCC_HAS_BUG_ but I think that could mess things up.

Kind regards

With Microblaze Gcc version < 8.x build hangs on compiling.
This is due to bug 85180:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180
This package has been excluded from building if BUG_85180 is present.
Bug shows up building ffmpeg with optimization.

In config.mk if BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y force using -O0 by:
- add --disable-optimizations to FFMPEG_CONF_OPTS
- passing -O0 to CFLAGS in FFMPEG_CONF_ENV
Then remove 'depends on !BR2_microblaze' from Config.in

With Microblaze Gcc version < 8.x build hangs on compiling first files.
This is due to bug 85180:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180
This package has been excluded from building if BR2_microblaze is
enabled.
Bug shows up building assimp with optimization but not when building
with -O0.

In config.mk if BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y force using -O0 by:
- passing -O0 to ASSIMP_CXXFLAGS
Then remove 'depends on !BR2_microblaze' and its comment if not
available from Config.in

With Microblaze Gcc version < 7.x build hangs on compiling first files.
This is due to bug 85862:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85862
This package has been excluded from building if BUG_85862 is present.
Bug shows up building libnss with optimization.

In config.mk append BUILD_OPT=1 only if
BR2_TOOLCHAIN_HAS_GCC_BUG_85862=y otherwise don't declare BUILD_OPT
forcing build system to not emit -O* flag.
Then remove 'depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85862' and its
comment if not available from Config.in

In fact why are we building with BUILD_OPT=1 at all ? This adds some
semi-random optimization flags decided by libnss. I guess we should not
pass BUILD_OPT=1 at all, and simply pass CFLAGS=$(LIBNSS_CFLAGS), with
LIBNSS_CFLAGS = $(TARGET_CFLAGS), with -O0 added to work around the
Microblaze bug.

What do you think ?

I totally agree. I've taken a closer look to what I've done on this 
patch, LIBNSS_CFLAGS are not setup and CFLAGS=".." passed to $(MAKE1) 
are actually ignored by libnss. Need to find a way to pass our 
$(TARGET_CFLAGS).

Actually libnss is configure with BUILD_OPT=1 that doesn't take into
account TARGET_CFLAGS nor TARGET_LDFLAGS resulting in pre-chosen
optimizations and debugging symbols.

Can't pass TARGET_CFLAGS through CFLAGS or similar otherwise other
iternal libnss will be overwritten(i.e. -fPIC), so prefer to append
TARGET_CFLAGS at the end of Linux.mk as well as TARGET_LDFLAGS according
to internal libnss Makefile system's names. And obviously remove
BUILD_OPT=1 from BUILD_VARS.

With Microblaze Gcc version < 8.x the build hangs due to bug 85862:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85862
To avoid this, the libnss package has a !BR2_TOOLCHAIN_HAS_GCC_BUG_85862
dependency. However, gcc bug 85862 only triggers when optimization is
enabled, so we can work around the issue by passing -O0, which is what
we do in other Buildroot packages to work around this bug.

libnss gcc bug 85862 has been worked around and that caused build
failure on Microblaze.

Remove 'depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85862' and 'depends on
!BR2_microblaze' from Config.in allowing this package to build.

I've seen you've tagged this as Changes Requested:
https://patchwork.ozlabs.org/patch/1103358/

It is because of dependency to "keyutils" still not fixed right?

Because this patch depends on the libnss patch, which was also marked
as Changes Requested.

'depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85862' is listed because libnss
was affected by that bug in latest Qt5, but now that bug has been worked
around.

So remove 'depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_85862' and allow
building latest Qt5 by removing also '|| BR2_PACKAGE_QT5_VERSION_5_6'.

Commit:
https://git.buildroot.net/buildroot/commit/?id=bad25aff36b70b55b34ea4580b45f657385ae9ac
removed sourcery toolchain already deprecated in 2014 causing build
failure. It was based on Gcc 4.6.2 and Buildroot doesn't use this
anymore.

Remove check against BR2_microblaze and BR2_sh2a.

This explanation is quite fuzzy. What is the relationship between the
removal of those toolchains and this particular issue ? Also this
commit only removes Microblaze toolchains, not SH2A toolchains.

Since when the LLONG_MAX issue has been fixed ?

Best regards,

Thomas

I improve commit log.

I've messed up, I need to remove BR2_microblaze only.

> Since when the LLONG_MAX issue has been fixed ?

Need to check and report on commit log.
