From 8a3b947c40cb36100f316ac0d433f4ae554ee4cc Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 18 May 2012 09:52:01 -0700 Subject: x86, relocs: When printing an error, say relative or absolute When the relocs tool throws an error, let the error message say if it is an absolute or relative symbol. This should make it a lot more clear what action the programmer needs to take. Signed-off-by: H.
