             Bug #: 13857
           Summary: "WARNING: Absolute relocations present" compiling
                    Linux kernel using -Wl,--icf=safe
           Product: binutils
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2

    Classification: Unclassified


I compiled Linux kernel 3.2.9 with Gentoo and CK patches and used the Gold
linker 1.11 from binutils 2.22. I added additional linker flags to the Makefile
including -Wl,--icf=safe. After compiling, I saw the error message:

I removed -Wl,--icf=safe and recompiled and did not receive the error again.
