Bug ID: 30187
Summary: ld.bfd and ld.gold versions in .comment section of ELF
files
Product: binutils
Version: 2.39
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: tkacvins at gmail dot com
CC: ian at airs dot com
Target Milestone: ---
Using a simple "hello world!" program
#include <stdio.h>
int main(int argc, char** argv)
{
printf("Hello world!\n");
return 0;
}
and then compiling with GCC 12.1 (or any GCC that supports -fuse-ld=gold)
gcc -fuse-ld=gold hello.c
Results in the ld.gold version not being in the .comment section. Ditto if one
uses ld.bfd.
However, if one uses a GCC that supports -fuse-ld=lld, one gets a linker
version in the .comment section
gcc -B /opt/lld-14.0.6/bin -fuse-ld=lld hello.c
$ readelf -p .comment a.out
String dump of section '.comment':
[ 0] GCC: (GNU) 4.8.5 20150623 (Red Hat 4.8.5-39)
[ 2d] Linker: LLD 14.0.6
[ 40] GCC: (GNU) 12.1.0
It would be nice if the gold and bfd linkers emitted their version into the
.comment section.
