Lto does not work on assembly, it only works if some IR is stored in the .o files (like gimple for gcc) iirc.

Currently.

However, that is not an inherent restriction - that is only a restriction on current compilers. It is entirely possible for a compiler to read the assembly of things being linked and optimize based on that.
