Bug ID: 20513
Summary: GNU ld does not ignore symbols defined in sections
marked EXCLUDE
Product: binutils
Version: 2.26
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: rguenth at gcc dot gnu.org
Target Milestone: ---
When linking two object files, one with a definition of symbol FOO and one with
a definition of symbol FOO in a section marked with SHF_EXCLUDE then GNU ld
complains about 'multiple definitions of 'FOO''. GOLD handles this situation
just fine.
t1.s:
.text
.section .text.startup,"ax",@progbits
.p2align 4,,15
.globl main
.type main, @function
main:
t2.s:
.text
.section .text.startup,"axe",@progbits
.p2align 4,,15
.globl main
.type main, @function
main:
(ignore assembler warnings about bogus section attributes)
> ld t1.o t2.o -o a.out
t2.o: In function `main':
(.text.startup+0x0): multiple definition of `main'
t1.o:(.text.startup+0x0): first defined here
> gold t1.o t2.o -o a.out
