Bug ID: 27441
Summary: Small inconsistency in between gold and bfd
Product: binutils
Version: 2.37 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: mliska at suse dot cz
CC: ian at airs dot com
Target Milestone: ---
I see the following discrepancy with the latest bintuils release:
$ cat umapfile.i
extern "C" int close(int);
void uprv_mapFile_67() {
int fd;
close(fd);
}
BFD:
$ g++ umapfile.i -O2 -c && g++ -o lib1.so -Wl,--as-needed -shared -lpthread
-fuse-ld=bfd umapfile.o && readelf -d lib1.so | grep NEEDED
0x0000000000000001 (NEEDED) Shared library: [libc.so.6]
GOLD:
$ g++ umapfile.i -O2 -c && g++ -o lib1.so -Wl,--as-needed -shared -lpthread
-fuse-ld=gold umapfile.o && readelf -d lib1.so | grep NEEDED
0x0000000000000001 (NEEDED) Shared library: [libpthread.so.0]
It seems close can be fulfilled by both libs, is there any guarantee which
library is selected for NEEDED?
