Message-Id: <20240812-nolibc-lto-v2-3-736af7bbefa8@weissschuh.net> Date: Mon, 12 Aug 2024 22:50:19 +0200 From: Thomas Weißschuh <linux@...ssschuh.net> To: Willy Tarreau <w@....eu> Cc: Ammar Faizi <ammarfaizi2@...weeb.org>, linux-kernel@...r.kernel.org, Thomas Weißschuh <linux@...ssschuh.net> Subject: [PATCH v2 3/3] tools/nolibc: x86_64: use local label in memcpy/memmove Compiling arch-x86_64.h with clang and binutils LD yields duplicate label errors: .../gcc-13.2.0-nolibc/x86_64-linux/bin/x86_64-linux-ld: error: LLVM gold plugin: <inline asm>:44:1: symbol '.Lbackward_copy' is already defined .Lbackward_copy:leaq -1(%rdi, %rcx, 1), %rdi Instead of a local symbol use a local label which can be defined multiple times and therefore avoids the error.
