From 63b6a48c951d63bf39d44603ada48a987ccf66eb Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Fri, 4 Sep 2026 21:44:23 +0800 Subject: [PATCH] LoongArch: Do not select HAVE_RUST when KASAN is enabled After commit 2625480a1bf7 ("hardening: Default randstruct off with rust for better allmodconfig support"), which allows Rust to be enabled for allmodconfig, ARCH=loongarch allmodconfig starts failing with: error: kernel-address sanitizer is not supported for this target error: aborting due to 1 previous error make[4]: *** [rust/Makefile:741: rust/core.o] Error 1 For the same reason as the commit 84a0f7caafc679f7 ("ARM: Do not select HAVE_RUST when KASAN is enabled"), do not select HAVE_RUST when KASAN is enabled until the loongarch64-unknown-none-softfloat target in rustc supports KASAN.
