[Buildroot] [PATCH v2] toolchain: remove binutils bug 21464

[Giulio Benetti]

This bug has been fixed upstream and backported to buildroot binutils
package. So let's remove it from toolchain/Config.in and from packages
that are affected by it:
- libgeos
- postgis
- protobuf

In fact, no I reverted this patch. It depends on other patches to be
applied first. This is an illustration of why you should *never* ever
resend just a single patch out of a larger series. Even if only one
patch is changed, please resend the entire series.

Could you update your "Fix binutils bug 21464 and remove it" series and
resend it?

Thanks,

Thomas

Oh, I see the reason, sorry.

[Buildroot] [PATCH v2 0/3] Fix binutils bug 21464 and remove it

[Giulio Benetti]

This patchset fixes binutils bug 21464 and fixes libgeos and protobuf
packages build failure by introducing the gcc option flag -mcmodel.
This is done by adding upstreamed binutils and gcc patches.

Note:
this way buildroot toolchains can be considered bug binutils 21464 free
and the only other OpenRisc toolchain supported is the external Bootlin
one. So this patchset has to be considered valid once Bootlin updates its
OpenRisc by adding binutils and gcc patches that are added with patches in
this patchset.

V1->V2:
* squashed patches [6..9/9] into one resulting into
"toolchain: remove binutils bug 21464" where binutils bug gets removed all
around buildroot. Note that this patch has been sent as v2 alone but it
shouldn't have been since was part of this patchset and before it the
other 2 patches which add -mcmodel=large to libgeos and protobuf must be
applied.

[Buildroot] [PATCH v2 1/3] package/libgeos: fix build failure due to missing -mcmodel=large

[Giulio Benetti]

When building libgeos for or1k -mcmodel=large is needed to link, so let's
add that gcc option in case we're building for or1k.

 According to git, -mcmodel was added to GCC after the 11.2.0 release. Are you
sure that this works?

 Oooh, we have a patch that adds it. But that patch is missing for 11.1.0 for
some reason. Romain, you apparently didn't carry any of our patches when you
added GCC 11 in 2ab88dac293aed5adf2504e8b182f9d8a306b935. The commit message
doesn't say anything. Do you remember anything about the patches? The patch was
added to master on May 21 and you only submitted the GCC bump on June 12, but
perhaps you already had it lying around for a while?

 Giulio, maybe you can port the patch to 11.1.0?

 Regards,
 Arnout

You've read into my mind :-), I've sent it yesterday:
https://patchwork.ozlabs.org/project/buildroot/list/?series=258108

and that is valid for both libgeos and profobuf.

Best regards!

Already sent and applied here :-):
https://git.buildroot.net/buildroot/commit/?id=137225cef423ccbebc31d0c562bf3f37192739ac

I'm going to add myself to toolchain as maintainer too, so I keep up to 
date on toolchain movement and also I've added a bunch of binutils/gcc
bugs. So it's time for it :-)

 Applied to master, thanks.

 I've added a comment to the commit message to explain that this option is from
a Buildroot patch.

 I've also applied the second patch with the same comment.

[Buildroot] [PATCH v2 2/3] package/protobuf: fix build failure due to missing -mcmodel=large

[Giulio Benetti]

When building protobuf for or1k -mcmodel=large is needed to link, so let's
add that gcc option in case we're building for or1k.

[Buildroot] [PATCH v2 3/3] toolchain: remove binutils bug 21464

[Giulio Benetti]

This bug has been fixed upstream and backported to buildroot binutils
package. So let's remove it from toolchain/Config.in and from packages
that are affected by it:
- libgeos
- postgis
- protobuf

 It's not clear to me if all the external toolchains that we use also have this
patch already. Basically that boils down to the stable and bleeding edge bootlin
toolchains.

 Well, I'm pretty sure they're not yet updated, since they're still  2020.08-1...

For this patch we have to wait until all or1k patches have been applied 
to Bootlin toolchain and they got rebuilt and bumped.
Then we can apply it since Buildroot will become OpenRisc bug free. But 
this depends on external OpenRisc toolchains that only Bootlin provide

Kind regards

Unfortunately libgeos is still affected by this bug and postgis too 
because it's its dependency. The reason is that libgeos has been bumped 
and I've never given a build after that.

Only protobuf has been fixed after rebuilding all Bootlin toolchains.
So I will report upstream that is usually very responsive and ask to fix 
this binutils again, hopefully once for all.

So please drop this patch. I'll send a patch for protobuf package only.

Best regards

[Buildroot] [PATCH] package/protobuf: drop dependency on binutils bug 21464

[Giulio Benetti]

This package build failure has been fixed by using -mcmodel=large that is
now available in external toolchains as well as buildroot toolchains. So
we can drop its dependency on binutils 21464.

I've updated the bug on the gcc side that works together with binutils 
on the fix:
