From 81a93bf93f0e5963d8695a3596ac50b5ceea87c3 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 26 May 2025 18:07:51 +0900 Subject: [PATCH] tinyconfig: enable CONFIG_LD_DEAD_CODE_DATA_ELIMINATION This CONFIG option, if supported by the architecture, helps reduce the size of vmlinux. For example, the size of vmlinux with ARCH=arm tinyconfig decreases as follows: text data bss dec hex filename 631684 104500 18176 754360 b82b8 vmlinux.before 455316 93404 15472 564192 89be0 vmlinux.after Signed-off-by: Masahiro Yamada --- kernel/configs/tiny.config | 1 + 1 file changed, 1 insertion(+) diff --git a/kernel/configs/tiny.config b/kernel/configs/tiny.config index b753695c5a8ff..5dd0f0a34a73c 100644 --- a/kernel/configs/tiny.config +++ b/kernel/configs/tiny.config @@ -2,3 +2,4 @@ CONFIG_CC_OPTIMIZE_FOR_SIZE=y CONFIG_KERNEL_XZ=y CONFIG_SLUB=y CONFIG_SLUB_TINY=y +CONFIG_LD_DEAD_CODE_DATA_ELIMINATION=y -- 2.39.5
