            Bug ID: 19278
           Summary: load segment created outside memory section specified
                    in linker script
           Product: binutils
           Version: 2.27 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gold
          Assignee: ccoutant at gmail dot com

  Target Milestone: ---

Created attachment 8802
  --> https://sourceware.org/bugzilla/attachment.cgi?id=8802&action=edit
Minimal example to reproduce

When using a linker script that contains MEMORY regions with gold, the
following warning is issued:

warning: creating a segment to contain the file and program headers outside of
any MEMORY region

Looking at the ELF data it looks like there is a LOAD segment that is getting
prepended to the first segment found. Since this will be at the memory
boundary, it will always fall outside the region.

I have attached a minimal assembly file and linker script to reproduce the
problem.

gcc -nodefaultlibs -nostartfiles -fno-PIE -o main main.s -Wl,-Tmain.lnk
-fuse-ld=gold

I have tried this on x86, x86_64, armv7 and aarch64 targets, all issue the same
warning.
