--- Comment #3 from Martin Liska <mliska at suse dot cz> ---
Great, thank you Vladimir. I was able to isolate that and reduce it. It started
with 20ea3acc727f3be6322dfbd881e506873535231d and it's regression since
20ea3acc727f3be6322dfbd881e506873535231d.
$ cat iotrace.i
extern __inline __attribute__((__gnu_inline__)) void open64(int, ...) {}
int __attribute__((__symver__("open64@GLIBC_2.2"))) __collector_open64_2_2() {}
void open64(int, ...) {}
$ cat libgprofng.ver
GLIBC_2.2 {
global:
open64;
};
$ gcc iotrace.i -shared -fPIC -O2 -Wl,--version-script,libgprofng.ver
-flto-partition=max -flto=auto -B ~/Programming/binutils/objdir/ld -fuse-ld=bfd
/usr/bin/ld.bfd: /tmp/ccLS2iVj.ltrans1.ltrans.o: in function `open64':
<artificial>:(.text+0x0): multiple definition of `open64@GLIBC_2.2';
/tmp/ccLS2iVj.ltrans0.ltrans.o:<artificial>:(.text+0x0): first defined here
collect2: error: ld returned 1 exit status
while -fuse-ld=mold or -fuse-ld=lld works fine. gold is also affected.
@H.J. Can you please take a look?
