Description
It would be nice if linker reports a warning if different shared libraries present in the link have the same SO name.
For example, we should report warning for the below example where lib1.so and lib2.so have the same SO name.
#!/usr/bin/env bash
cat >1.c <<\EOF
int foo() { return 1; }
EOF
cat >2.c <<\EOF
int bar() { return 3; }
EOF
clang -o 1.o 1.c -target arm -c -ffunction-sections
clang -o 2.o 2.c -target arm -c -ffunction-sections
ld.eld -o lib1.so 1.o -shared -soname=foo
ld.eld -o lib2.so 2.o -shared -soname=foo
ld.eld -o a.out /dev/null lib1.so lib2.so
