[Bug ld/19327] New: [AArch64] ld should issue an error if a shared library is built from a non-PIC object
https://sourceware.org/bugzilla/show_bug.cgi?id=19327
Bug ID: 19327
Summary: [AArch64] ld should issue an error if a shared library
is built from a non-PIC object
Product: binutils
Version: 2.27 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: ikudrin.dev at gmail dot com
Target Milestone: ---
On host (Ubuntu 15.10, x86_64):
$ cat d.c
int d = 5;
int f() { return d; }
$ cat m.c
#include
int d = 42;
int f();
int main() {
printf("%d\n", f());
return 0;
}
$ aarch64-linux-gnu-gcc -c d.c -o d.nopic.o
$ ld.git -shared d.nopic.o -o d.ld.nopic.so
$ aarch64-linux-gnu-gcc m.c ./d.ld.nopic.so -o r.ld.nopic
$ aarch64-linux-gnu-gcc -c d.c -o d.pic.o -fPIC
$ ld.git -shared d.pic.o -o d.ld.pic.so
$ aarch64-linux-gnu-gcc m.c ./d.ld.pic.so -o r.ld.pic
Note: ld.git is just built from git sources.
On VM with AArch64 Debian:
$ ./r.ld.nopic
5
$ ./r.ld.pic
42
Expected bahavior: should report an error similar to other targets:
$ gcc -c d.c -o d.nopic.o
$ ld -shared d.nopic.o -o d.nopic.so
ld: d.nopic.o: relocation R_X86_64_PC32 against symbol `d' can not be used when
making a shared object; recompile with -fPIC
