OK, so all IR objects are converted into a single .o file encapsulating the module image. Does this give the same benefits as LTO linking IR objects to a fully linked executable? Even if it does, partial linking is not something the toolchain people are usually crazy about, so it would be nice to have some confirmation that this is a usage model that is fully supported.
