__attribute__((visibility("protected"))) void *foo() {
return (void *)foo;
}
gcc -fpic -shared -fuse-ld=bfd fails with the confusing diagnostic:
relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `foo' which may bind externally can not be used when making a shared object; recompile with -fPIC
Call _bfd_elf_symbol_refs_local_p with local_protected==true to suppress
the error. The new behavior matches gold and ld.lld.
Note: if some code tries to use direct access relocations to take the
address of foo (likely due to -fno-pic), the pointer equality will
break, but the error should be reported on the executable link, not on
the innocent shared object link. glibc 2.36 will give a warning at
relocation resolving time.
