This is important for Frameworks, which are usually symlinks. ld64 gets this right for @rpath that's replaced with @loader_path, but not for bare @loader_path -- ld64's code calls realpath() in that case too, but ignores the result. ld64 somehow manages to find libbar1.dylib in the test without the explicit `-rpath` in Foo1. I don't understand why or how. But this change is a step forward and fixes an immediate problem I'm having, so let's start with this :) Differential Revision: https://reviews.llvm.org/D103990
