From 852fed2e8bfe195351fb0078ba7245d41154e7a5 Mon Sep 17 00:00:00 2001 From: Rosen Penev Date: Thu, 7 May 2026 17:08:34 -0700 Subject: [PATCH] sparc: Disable compat support with LLD An LLVM=1 sparc64 allmodconfig enables COMPAT and then tries to build the 32-bit vDSO. That path cannot be linked with ld.lld: ld.lld: error: unknown emulation: elf32_sparc ld.lld does not support the 32-bit SPARC ELF emulation used for the compat vDSO, so keep COMPAT disabled when LLD is the linker. This avoids selecting an unsupported build path while leaving the existing GNU ld configuration unchanged.
