Message-Id: <E1SHnDZ-0006Za-Kh@tytso-glaptop.cam.corp.google.com> Date: Tue, 10 Apr 2012 22:23:33 -0400 From: "Theodore Ts'o" <tytso@....edu> To: linux-kernel@...r.kernel.org, hjl.tools@...il.com Subject: Trying to make a working kernel with the gold linker So I was trying to see if I could make the kernel build with the gold linker (since until it can, I can't install it on my system). I saw a message from HJ indicating one of the problems was x86_64 gold used an incompatible max-page-size setting, so I tried changing it in hopes that would make a bootable kernel. No dice, it didn't work. (At least not with a 2.20 binutils-gold.) Does anybody know what the other issues with the gold linker? Is the 2.22 binutils-gold more likely to work?
