            Bug ID: 19854
           Summary: Build fails with gcc<4.9: -Wstack-usage not support
           Product: binutils
           Version: 2.27 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: faraz.shahbazker at imgtec dot com
  Target Milestone: ---

Build fails because older gcc versions (<4.9) do not have a -Wstack-usage=
option. Problem commit is: e1fa0163505af867009ea73fc5f705162120e795

Configured with:
/scratch/gcc/nightly/src/binutils/configure --enable-werror
