Bug ID: 16515
Summary: objcopy cannot weaken undefined symbols
Product: binutils
Version: 2.22
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: srk31 at srcf dot ucam.org

Patch to fix the bug
It is meaningful to weaken an undefined symbol. Currently objcopy silently
omits to do this when asked.
The attached patch fixes this for me.
(Note that by contrast, localizing and globalizing -- which are done
immediately after weakening in the code -- are, I think, only meaningful for
defined symbols. Perhaps this explains why the weakening code doesn't handle
the undefined case.)
