guix: native GCC 10 toolchain for Linux builds #25076

fanquake commented at 2:00 PM on May 6, 2022: member

Completes the migration to using a native GCC 10 toolchain for all HOSTS. This change means we'll now use GCC 10 when compiling glibc and friends (currently we use GCC 7), which is the same as our release compiler, except for macOS (Clang 10). Note that Guix has also switched it's default compiler from GCC 7 to GCC 10. See each commit for more details.

In e138dead3f85fd85c791d6ec0fd41e69fa69d775 "guix: compile glibc without -werror" is it possible to specify -Wno-error=... explicitly to clearly document problematic warnings?

If 15760c4cdb5eab8a221c27bb84545f4ccd4b9389 "guix: fix glibc 2.27 multiple definition warnings with GCC 10" is about warnings, why is it required after disabling -Werror in e138dead3f85fd85c791d6ec0fd41e69fa69d775?

d309a15649b052103730e1a2ffe806e80779dac2 "guix: use -fcommon when building glibc 2.24" From GCC docs:

The -fcommon places uninitialized global variables in a common block. This allows the linker to resolve all tentative definitions of the same variable in different compilation units to the same object, or to a non-tentative definition. This behavior is inconsistent with C++, and on many targets implies a speed and code size penalty on global variable references. It is mainly useful to enable legacy code to link without errors.

Considering this, maybe limit this patch to the powerpc hosts only?

Different (HOST) compilers may warn in different ways, and I'm not sure of the benefit of listing all these out. It'd also remove the ability to simply set enable_werror.

"guix: fix glibc 2.27 multiple definition warnings with GCC 10" is about warnings, why is it required after disabling -Werror in https://github.com/bitcoin/bitcoin/commit/e138dead3f85fd85c791d6ec0fd41e69fa69d775?

It's to fix a link issue (-fcommon). Turning compiler warnings into errors, or not, is unrelated.

Considering this, maybe limit this patch to the powerpc hosts only?

I don't really want to start configuring / compiling HOST glibcs differently (RISCV is already an exception).

MarcoFalke commented at 1:53 PM on May 10, 2022: member

No objection, but I wonder what user-facing improvement this brings. In fact, it might be slightly disadvantageous to compile an ancient tool with a modern compiler, as we are likely the first ones to do so, putting our users on an "unexplored" path. Moreover, it might actually make it harder to bump gcc at a later point, requiring even more patches to compile the ancient glibc with an even more modern compiler.

Wouldn't it be better to not touch this until gcc is bumped or alternatively until glibc is removed?

No objection, but I wonder what user-facing improvement this brings.

As with the majority of the changes that are merged into this repository, there may be little-to-no end-user facing improvement. The developer-facing improvement, is a simpler Guix toolchain, and improved build times.

Moreover, it might actually make it harder to bump gcc at a later point, requiring even more patches to compile the ancient glibc with an even more modern compiler.

This change shouldn't make it any harder to bump (release) GCC. The release compiler and native compiler can exist independently of each other, as they do now. If, some time into the future, we want to use GCC 13 to build our release binaries, because we need support for C++20, then we split them back out, while continuing to use GCC 10 to compile glibc.

Wouldn't it be better to not touch this until gcc is bumped

I would like to consolidate to GCC 10, and simplify our Guix toolchain.

or alternatively until glibc is removed?

Do you mean until some sort of migration to musl libc? Otherwise I don't know what you mean by glibc being removed, as it is required to provide a functioning toolchain.

OT: Heh, I hope this is not true. I consider code changes that make the code less susceptible to bugs a (minimal) user-facing improvement.

Concept ACK

Although I personally don't care that we're on the same GCC version everywhere, I think this change is good overall mostly because Guix has moved from gcc-7 to gcc-10 as the default toolchain as of our guix time-machine commit. So there will be more eyes on the gcc-10 package and it will be exercised or tested against more things.

guix: compile glibc without -werror

Compiling glibc 2.24 and 2.27 with the new GCC 10 results in a number of new warnings,
i.e:
```bash
libc-tls.c: In function ‘__libc_setup_tls’:
libc-tls.c:208:30: error: array subscript 1 is outside the bounds of an interior zero-length array ‘struct dtv_slotinfo[0]’ [-Werror=zero-length-bounds]
  208 |   static_slotinfo.si.slotinfo[1].map = main_map;
      |   ~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~
In file included from ../sysdeps/x86_64/ldsodefs.h:54,
                 from ../sysdeps/gnu/ldsodefs.h:46,
                 from ../sysdeps/unix/sysv/linux/ldsodefs.h:25,
                 from libc-tls.c:20:
../sysdeps/generic/ldsodefs.h:398:7: note: while referencing ‘slotinfo’
  398 |     } slotinfo[0];
      |       ^~~~~~~~
```

While we could try and backport all the patches required to fix these up, it would
currently seem easier to disable -Werror, which Guix uses by default when building
glibc.

guix: adjust RISC-V __has_include() patch to work with GCC 10

The actual macro is __has_include(), not __has_include__(), using the
later would result in build failures when using GCC 10. i.e:
```bash
../sysdeps/unix/sysv/linux/riscv/flush-icache.c:24:5: warning: "__has_include__" is not defined, evaluates to 0 [-Wundef]
   24 | #if __has_include__ (<asm/syscalls.h>)
```

Looks like at least someone else has run into the same thing, see:
http://lists.busybox.net/pipermail/buildroot/2020-July/590376.html.

guix: fix glibc 2.27 multiple definition warnings with GCC 10 0e51913595

guix: use -fcommon when building glibc 2.24

GCC 10 started using -fno-common by default, which causes issues with
the powerpc builds using gibc 2.24. A patch was commited to glibc to fix
the issue, 18363b4f010da9ba459b13310b113ac0647c2fcc but is non-trvial
to backport, and was broken in at least one way, see the followup in
commit 7650321ce037302bfc2f026aa19e0213b8d02fe6.

For now, retain the legacy GCC behaviour by passing -fcommon when
building glibc 2.24.

ACK 6b9d53e1ff0099a8d9abb3c389df96fa75eac3f5

Maybe reword "we'll now use GCC 10 when compiling glibc and friends..., which is the same as our release compiler" in the PR description as it does not look as a true justification, and replace it with "Guix has moved from gcc-7 to gcc-10 as the default toolchain" from #25076 (comment)?

fanquake commented at 8:56 AM on May 18, 2022: member

I've added a sentence about Guix having swapped it's default compiler; note that Guix having swapped to GCC 10 as their default compiler was also part of the reasoning for #23778.
