This is a cross build on a PowerPC LE host. $ rustc --version rustc 1.80.1 $ x86_64-linux-gnu-gcc --version x86_64-linux-gnu-gcc (Debian 14.2.0-1) 14.2.0 I have reverted these commits for today: a2f115470520 ("kasan: rust: Add KASAN smoke test via UAF") e3117404b411 ("kbuild: rust: Enable KASAN support") f64e2f3a66e3 ("rust: kasan: Rust does not support KHWASAN") c42297438aee ("kbuild: rust: Define probing macros for rustc") cc1d98f9fe30 ("kasan: simplify and clarify Makefile") ca627e636551 ("rust: cfi: add support for CFI_CLANG with Rust") Basically for the latter one (as a guess). And the build works. --=20 Cheers, Stephen Rothwell --Sig_/wANEv3YAoDiVFAl6pjs/tH1 Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmb0pRIACgkQAVBC80lX 0Gw/QAf/UUa74b3h4LdmwUdqWoi5urJVUt9qsu/dyY35z8CZUSsZ9NPnbGz238On VmnV+Qzn7xAg5RT3jJ4IgseR1EYR6B1mWKh440QwQ3mOU2AT7gMxefNv+oNi3Ta9 gkksyRVmiqXJvnKmu78wYV8AhM10lDgDPv9nsV5y94yHlgP0BIS/GvIpDnxkXrXs RliKH+KbNxP02+GpPQGmidVj4C4UbeOjmQqoVuuxgQWpB2BNbDujiutMlX7cOKnw u2Lb48kUSUD4ZjHGu9hn2FIO3/LXjF0sRKMaY84+6bYa4bNhe4CKI9IhRQwypZ5y 7NUGQzRAs0TpFhg7UTXsH5VgcQgPPw== =p3KM -----END PGP SIGNATURE----- --Sig_/wANEv3YAoDiVFAl6pjs/tH1--
