Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Fri, 18 May 2012 09:52:01 -0700 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.
