From: Ammar Faizi Date: Tue, 29 Mar 2022 10:17:31 +0000 (+0700) Subject: tools/nolibc: Remove .global _start from the entry point code X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1590c59836dace3a20945bad049fe8802c4e6f3f;p=linux.git tools/nolibc: Remove .global _start from the entry point code Building with clang yields the following error: ``` :3:1: error: _start changed binding to STB_GLOBAL .global _start ^ 1 error generated. ``` Make sure only specify one between `.global _start` and `.weak _start`. Remove `.global _start`. Cc: llvm@lists.linux.dev Reviewed-by: Nick Desaulniers Acked-by: Willy Tarreau Signed-off-by: Ammar Faizi Signed-off-by: Paul E.
