Bug ID: 25882
Summary: .gnu.attributes are not checked for shared libraries
Product: binutils
Version: 2.35 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: amodra at gmail dot com
Target Milestone: ---
ld/ldlang.c lang_check calls bfd_merge_private_bfd_data from within a block
conditional on bfd_count_sections (input_bfd). It makes sense to exclude
relocatable objects without contents, but since shared libraries do not have
sections loaded by the ELF linker (see elflink.c:4337 bfd_section_list_clear
call), the condition stops .gnu.attributes processing for shared libraries.
gold on the other hand does process .gnu.attributes for shared libraries.
