From e0f31baacc6ad30096a332b69433c85f5830bb2c Mon Sep 17 00:00:00 2001 From: Jakub Kądziołka Date: Thu, 30 Jul 2020 02:21:54 +0200 Subject: build-system/gnu: strip with --strip-unneeded [v2] [Accidentally pushed patch v1, this commit contains the rest of the changes. Revised commit message follows.] Apart from debug information, one can also strip some symbols. This can be a significant difference, the closure of gcc-toolchain@7 got reduced by 15 MB in my tests. As per [1], --strip-debug is included in --strip-unneeded, and the debug files created also contain a copy of the information removed by --strip-unneeded. Linux From Scratch suggests that this option shouldn't be used on static libraries [2], however other sources [3] indicate otherwise. Building a toolchain with this patch succeeds, and the result works fine for 'gcc -static hello-world.c'.
