Bug ID: 19617
Summary: ELF: Allow -E to work without -pic/-pie/-shared in the
absence of undefined symbols
Product: binutils
Version: 2.27 (HEAD)
Status: NEW
Severity: enhancement
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: hpa at zytor dot com
Target Milestone: ---
If neither -pic, -pie, or -shared is specified, *and* there are no undefined
symbols in the executable, ld produces no dynamic sections. However, if -E is
specified, the executable is supposed to export its symbols to modules loaded
in the future.
This configuration is common in embedded environments, including boot loaders.
The current workaround is to use -pie, but that generates a manifest .rel.dyn
section which is pure waste if -pie isn't actually required.
