            Bug ID: 101246
           Summary: gccgo cross-compiler targeting arm fails to build with
                    gcc 11. Missing structs in runtime.inc. Using
                    uclibc-ng
           Product: gcc
           Version: 11.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
          Assignee: ian at airs dot com
          Reporter: lancethepants at gmail dot com
                CC: cmang at google dot com
  Target Milestone: ---

I've recently run into an issue building a go cross-compiler on x86_64
targeting an arm embedded device (Netgear R7000 router) starting with gcc 11.

I was previously able to build the cross-compiler (c,c++,go) under gcc 9 & 10,
but am getting the errors listed at the bottom.

armv7 cortexa9 cpu (no fpu)
uclibc-ng (latest)
kernel 2.6.36.4.

I don't think the old kernel is an issue because the same errors arise if I use
kernel 5.12.  

I tried building with glibc, and it does work then. So I think the issue is
with uclibc-ng.

So I did use uclibc-ng with gcc 9 & 10 with success, but for some reason with
gcc 11 I am now running into this issue.

My untrained eyes think it may be as easy as a couple missing structs within
runtime.inc.   Is runtime.inc generated? because it doesn't appear in
unconfigured source I've notices.

thanks,
Lance

--- Comment #1 from Ian Lance Taylor <ian at airs dot com> ---
Yes, runtime.inc is a generated file.  Can you post the lines around the
errors? 
 These look like fields in a struct type, and I'd like to know which type it
is.  Thanks.

--- Comment #3 from Ian Lance Taylor <ian at airs dot com> ---
Thanks, but I am hoping to see not the build log, but rather the contents of
the generated file TARGET/libgo/runtime.inc, around lines 1357 and 1360. 
Thanks.

Just to check another architecture, I tried building gccgo-11 for x86_64 and
uclibc-ng.  With gcc-11 I get the same build-time error with x86_64 as I did
with arm. 

gccgo-10 for x86_64 & uclibc-ng did build, but when compiling a simple program
I get a few undefined errors I don't have with arm.
undefined reference to `__wrap_pthread_create'
undefined reference to `__morestack_block_signals'
undefined reference to `__generic_morestack'
undefined reference to `__morestack_unblock_signals'

Probably needs to be its own bug report. Not sure if gcc-10 will see more
releases, but I would guess it would still be present in gcc-11 if it built.

I hope uclibc-ng still gets some love from gcc and is supported.  It plays nice
with old kernels, has more supported targets, and is still actively developed.

So I compared runtime.inc in gcc 10.3 and gcc 11.1, and they have quite a bit
different.  I tried using the runtime.inc file from 10.3 in 11.1, and it does
allow it to finish compiling, and I appear to be able to compile a simple go
program.  

I also just removing struct _FILE, which has those to fields __lock and __state
and also completes and I appear to be able to compile some simple go programs.

Not sure if any of this is helpful. I've been trying to figure out all the file
generation is happening, but it's a lot to take in.

[Bug go/101246] gccgo cross-compiler targeting arm fails to build with gcc 11. Missing structs in runtime.inc. Using uclibc-ng

So this is the patch I'm using to build gccgo for uclibc arm.

https://raw.githubusercontent.com/lancethepants/tomatoware/master/patches/gcc/0006-fix-libgo-uclibc-ng.patch

In a seperate discussion you mentioned excluding the struct from generation,
and this seems to work fine. It'd be nice to see this upstreamed but submitting
for gcc looks like a high barrier to entry.

    mkruntimeinc: skip _FILE

    We don't need it, and it breaks uclibc.
