guix: disable LTO in GCC #35261

1. 
   fanquake commented at 3:19 PM on May 11, 2026: member

   We don't use LTO in release builds, and neither do any of our dependencies, so disable support in GCC (--disable-lto):

   Enable support for link-time optimization (LTO). This is enabled by default, and may be disabled using --disable-lto.

   This reduces what needs to be compiled when building the Guix toolchain. It would also make it clear if something started using it.

   Also disable Native Language Support (--disable-nls):

   The --enable-nls option enables Native Language Support (NLS), which lets GCC output diagnostics in languages other than American English. Native Language Support is enabled by default if not doing a canadian cross build.

   Also disable support for transactional memory (--disable-tm-clone-registry):

   Disable TM clone registry in libgcc. It is enabled in libgcc by default. This option helps to reduce code size for embedded targets which do not use transactional memory.

   See https://gcc.gnu.org/install/configure.html.

   in the PR description:

   saves some compilation

   i'd like to assume you meant 'saves some compilation time' rather than 'saves some compilation' - is that right ?

   Maybe both? Skipping LTO means compiling less stuff (albeit not much) in Guix, when building the toolchain, which ultimately saves some time (across 6 toolchains).

   correct!

   how about updating it to something like: 'This reduces what needs to be compiled and saves some compilation time when building the toolchain'? that way it captures both aspects you mentioned in turn making the description clearer

   (just a suggestion though, no worries either way!)

    ACK 313ed191e9d46bb19012e677e9a8ec3c95d693b7.

    Review comments below.

    Nits:

    • Avoid swapping lines to make diffs easier to review. Example: posix and ssp flags are swapped on mingw. Same for linux.
    • The change from an ordinary quasiquote to a gexp is not mentioned in the PR. This limits the minimum supported Guix version, but it is not an issue because the syntax is used elsewhere in the codebase and the project pins the Guix version (to c5eee3336cc1d10a3cc1c97fde2809c3451624d3). Gexps in arguments are available since 1.3.0, May 2021 (see compatibility note here and release date here). Gexps is also the preferred syntax. Also, the trailing commas used before were actually no-op quasiquotes.
    • --enable-gprofng=no added to mingw, not mentioned in the PR description. Was part of linux flags before.
    • --disable-libsanitizer is not mentioned in the PR description. Not an issue because it should not be used with release builds, it was also part of linux flags before.

    Minor:

    • --disable-tm-clone-registry is added only to linux-base-gcc, not mingw-w64-base-gc. Is this not available on mingw? Also not mentioned in the PR description.
    • depends/Makefile:45 has an LTO setting (but it's empty/off). Not sure whether that one should be removed as well.

    Hashes on that commit (same as multiple people above):

    @nkaretnikov thanks for taking a look.

    Avoid swapping lines to make diffs easier to review. Example: posix and ssp flags are swapped on mingw. Same for linux.

    Lines are being swapped on purpose.

    depends/Makefile:45 has an LTO setting (but it's empty/off). Not sure whether that one should be removed as well.

    No, this can remain.

    --disable-tm-clone-registry is added only to linux-base-gcc, not mingw-w64-base-gc. Is this not available on mingw?

    It's only valid on Linux.

    You've mentioned a number of times about things being missing from the PR description; I don't think the PR description needs to duplicate the entire content of all commits/commit messages, however I might add some more content.

    I appear to still be stuggling to get matching hashes here :'(

    Seems likely to be an issue with my setup, rather than this PR.

    @willcl-ark are you building in a bix env? that’s what I used.

    https://github.com/bitcoin-dev-tools/bix

    UPD: actually, nevermind, I remembered that I then enabled the guix service in nixos settings, so the env had no effect on the build since guix used its own toolchain.

    Well I am still at a loss as to why my linux builds don't match. I've tried cleaning all depends/caches that I can think of, as well as rebuilding gcc toolchain, and doing no-substitute builds, but to no avail.

    If any builders (with matching hashes for 313ed191e9d4) still have their build dir about, perhaps they might be able to check the output of:

    #!/usr/bin/env bash
    set -euo pipefail
    
    host=x86_64-linux-gnu
    build="guix-build-313ed191e9d4"
    profile=$(readlink -f "$build/var/profiles/$host")
    cxx="$profile/bin/$host-g++"
    libgcc=$("$cxx" -print-libgcc-file-name)
    libstdcpp=$("$cxx" -print-file-name=libstdc++.a)
    
    printf 'PROFILE %s\n' "$profile"
    sha256sum \
      "$(readlink -f "$cxx")" \
      "$libgcc" \
      "$libstdcpp"
    

    I get:

    Thanks @nkaretnikov. I guess I need to go even deeper into the rabbit hole...

    nkaretnikov commented at 10:12 AM on July 21, 2026: none

    @willcl-ark I suggest checking in with the guix team. There are certain configurations where you can introduce "impurities" into the build process, which will result in hashes being different. Something like setting an environment variable that gets inherited. I don't know the exhaustive list at the moment.

    Unless you have done so already, I would recommend trying after a reboot and with a clean shell profile just in case.

    If reproducing on that particular machine is not the goal, I would also consider setting up a new host from scratch.

    Please let me know if you want me to run additional tests.

    @nkaretnikov I do perhaps one further check I would ask you to run, if you don't mind. Perhaps we can jump into #bitcoin-core-builds on libera though; I've already derailed this PR enough!

    Not a blocker IMO, but do we mind that the windows bootstrap compiler still has LTO enabled?

    LTO is disabled for the Linux bootstrap compiler via linux-base-gcc, while the MinGW bootstrap compiler is constructed from base-gcc.

    The final windows compiler uses mingw-w64-base-gcc with LTO disabled, as indended.
