#--- def.s
#--- ref.s
.globl fun
fun:
bl foo@PLT
#--- main.s
.globl _start
_start:
bl fun@PLT
% llvm-mc -filetype=obj -triple=aarch64 main.s -o main.o
% llvm-mc -filetype=obj -triple=aarch64 def.s -o def.o && ld.lld -shared def.o -o def.so
% llvm-mc -filetype=obj -triple=aarch64 ref.s -o ref.o && ld.lld -shared ref.o -o ref.so def.so
```
# ld
ld will report warning:
```
% ld main.o ref.so
ld: warning: def.so, needed by ref.so, not found (try using -rpath or -rpath-link)
ld: ref.so: undefined reference to `foo'
```
# lld
No alarm is generated when lld is linking.
```
% lld main.o ref.so
```
I think the behavior of ld is more reasonable.
Can we add alarms for lld?
