Bug ID: 21518
Summary: ld.gold should igmore -pie flag for --oformat=binary
mode (ld.bfd does)
Product: binutils
Version: 2.27
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: slyfox at inbox dot ru
CC: ian at airs dot com
Target Milestone: ---
It came up as a build failure of dosemu on gcc-7 with --enable-default-pie:
https://bugs.gentoo.org/show_bug.cgi?id=618366
Simple reproducer (imagine '-pie' is a default):
$ cat a.S
.text
.code16
.globl _start16
_start16:
# this works
$ gcc -pie -fuse-ld=gold -Wl,-Ttext,100,-e,_start16,--oformat,binary -nostdlib
-s -o foo.com a.S
/usr/lib/gcc/x86_64-pc-linux-gnu/7.1.0/../../../../x86_64-pc-linux-gnu/bin/ld.gold:
fatal error: binary output format not compatible with -shared or -pie or -r
collect2: error: ld returned 1 exit status
# this fails
$ gcc -pie -fuse-ld=bfd -Wl,-Ttext,100,-e,_start16,--oformat,binary -nostdlib
-s -o foo.com a.S
Arguably '-pie' has no role here as the output format is not really an ELF.
$ x86_64-pc-linux-gnu-ld.gold --version
GNU gold (Gentoo 2.27 p1.0 2.27) 1.12
