From d681b22ed77274a805c6c8e81925c18eeb57a968 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Tue, 11 Mar 2014 17:58:08 +0000 Subject: automake: ask the linker to do garbage collection By doing GC the linker removes all the symbols that are not referenced and/or used by the final library. This results in a saving of ~100K up-to ~600K per (stripped) binary (classic vs gallium drivers). If interested one can ask the compiler to print the sections that are removed using -Wl,--print-gc-sections. v2: Check if ld supports the flag before using it.
