guix: use GCC 14.3.0 over 13.3.0

fanquake commented at 1:12 pm on November 4, 2025: member

Switching to using GCC 14.x for release builds has come up multiple times recently. It will eventually be needed for #25573, and could also be useful for #30210.

Why 14.3.0 specifically, and not 14.2.0?

(asking because 14.2.x is mentioned in https://gist.github.com/hebasto/dee3c918da49ee767ccf5eea43276407).

fanquake commented at 1:51 pm on November 4, 2025:

I’d rather we use the version of the compiler with more bug fixes, and less known bugs.

hebasto commented at 11:57 pm on December 8, 2025:

Why not use the same minor version for both gcc-14 and gcc-toolchain-14 packages?

fanquake commented at 5:29 pm on December 10, 2025:

It shouldn’t make any difference, for building host tools. It also seems non-trivial to swap out the version in gcc-toolchain-14.

Diffing bitcoind.exe built on x86_64 and aarch64, the offending symbols are:

0wallet::SQLiteDataFile(fs::path const&)
1wallet::ListDatabases[abi:cxx11](fs::path const&)
2std::pair<fs::path, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >& std::vector<std::pair<fs::path, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<std::pair<fs::path, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >::emplace_back<fs::path const&, char const (&) [4]>(fs::path const&, char const (&) [4]).isra.0

Seeing the following difference:

That’s such a strange difference. Just register selection.

We should probably aim to create a minimum reproduction, to be able to report and troubleshoot this. (running builds on x86_64, arm64 and riscv64)

I tried comparing debug info from GCCs passes, the first one that seems to differ is objsz1:

So that seems like compute_builtin_object_size is returning a different value based on the host arch?

So that seems like compute_builtin_object_size is returning a different value based on the host arch?

Wonder if there’s any windows-specific code paths for that in mingw64? After all, we’re not seeing it when building for the other targets and architectures.

laanwj commented at 12:20 pm on December 3, 2025: member

Looks like riscv64 matches aarch64. x86_64 is the odd one out.

To build, i’m currently carefully reproducing the conditions of Bitcoin Core’s build system. i’m not sure in how far this is necessary, but remapping the /gnu/store prefixes is important, otherwise the platforms output differs.

These are critical, without them, the non-determinism goes away:

#include <cstring>
Defining and using fs::path
IsBDBFile and IsSQLiteFile are defined and used, and have some logic in them

i think these are purely to prevent the compiler from inlining std::vector<std::pair<fs::path, std::string>>::emplace_back, which would cause the logic that causes the divergence in objsz1 to not be hit.

The non-determinism also goes away if you build with _FORTIFY_SOURCE=2 instead of _FORTIFY_SOURCE=3. The difference there should be that the headers are using __builtin_dynamic_object_size in the =3 case, instead of __builtin_object_size.

@maflcko suggested just declaring the util functions. This has reduced test.cpp further, with the same non-determinism (https://github.com/fanquake/bitcoin/commit/c12ef2a5312cb66cd01a2f1230fe4e976759f4e1).

Here’s a patch to manifest.scm that makes it easier to test with arbitrary gcc commits: https://github.com/laanwj/bitcoin/commit/3ab504a97997dc0a2bb0b7b0e849459e42d3c316

Allows:

0GCC_COMMIT=953536524a198efa932ee2cccf5d29d4fc1d24f3 GCC_HASH=3b59e003321ac50462f626bba07826c2d4c203d4fd1500c64d2ea332e61eaab0 HOSTS="x86_64-w64-mingw32" contrib/guix/guix-build

GCC_COMMIT is any arbitrary commit from the gcc repository (any will work as long as the patches apply).
GCC_HASH is the hex sha256sum of the tar.gz file for the commit. Sadly guix won’t work without a hash, but unlike the base32 ones this one is easy to pre-generate with stock utilities.

FWIW i’ve checked

bisecting wlll go back to an ancient merge base (8e08c7886eed5824bebd0e011526ec302d622844) that breaks guix’s patching, sadly.

It might be possible to cut down the toolchain (reduce the number of stages) for faster builds. Especially if we pre-preprocess test.cpp. But i haven’t looked into this yet.

FWIW: My bisect is not done yet (2 steps to go, it will likely finish today), but in the current commit range https://github.com/gcc-mirror/gcc/commit/1d82fc2e6824bf83159389729c31a942f7b91b04 optimize std::vector::push_back is the most suspicious as it affects vector appending. It’s a change to libstdc++-v3, not the compiler, so it doesn’t directly point at a root cause. (it would be an easy thing to revert though, and experimenting with it is less involved than having to recompile the compiler)

Edit: confirmed:

 5
 6    optimize std::vector::push_back
 7
 8    this patch speeds up the push_back at -O3 significantly by making the
 9    reallocation to be inlined by default.  _M_realloc_insert is general
10    insertion that takes iterator pointing to location where the value
11    should be inserted.  As such it contains code to move other entries around
12    that is quite large.
13
14    Since appending to the end of array is common operation, I think we should
15    have specialized code for that.  Sadly it is really hard to work out this
16    from IPA passes, since we basically care whether the iterator points to
17    the same place as the end pointer, which are both passed by reference.
18    This is inter-procedural value numbering that is quite out of reach.
19
20    I also added extra check making it clear that the new length of the vector
21    is non-zero.  This saves extra conditionals.  Again it is quite hard case
22    since _M_check_len seem to be able to return 0 if its parameter is 0.
23    This never happens here, but we are not able to propagate this early nor
24    at IPA stage.

Edit2: Here’s a branch that upgrades gcc to 14.3.0 but reverts that commit: https://github.com/laanwj/bitcoin/tree/2025-12-gcc-upgrade . It currently does this for all platforms, whereas mingw would be enough, but it’s just for testing.

Output matches, as expected:

The first variant (test-original.cpp.i) is preprocessed with gcc -E with the original gcc 14.3.0 headers, the second one (test-reverted.cpp.i) with the reverted commit. Note that we could now drop HOST_CXXFLAGS with the remaps (as well as all the explicit CROSS_ environment setup) as the file was preprocessed on one host, having the same paths.

guix: Revert part of GCC commit "optimize std::vector::push_back" to restore determinism 92f275aabf

ci: migrate some jobs to Debian Trixie, use GCC 14 a72ff31b87

In 92f275aabf12ebfc0d6d0ccbd83af7e4f88dad25:

From the partially reverted commit message, it follows that the commit affects code generation at -O3. This is somewhat confusing, as we use -O2.

Based on that commit message, I conclude that reverting only the two checks, rather than the entire commit, is safe. Nevertheless, why not revert the whole commit, which would make review of this PR much easier?

I’d say it is easier to check that dead/unreachable code has been removed than to check the correct port of a optimization reversion across gcc minor or even major versions?

IMO this is safer. It removes only unreachable code, which is enough to remove the non-determinism. Reverting the optimization seems more risky especially for platforms where this is not needed. (and there’s no reason to believe that the optimization is unsafe and needs to be reverted? the problem is only the non-determinism)
