   Without ``--fat-lto-objects``, LLD will link LLVM FatLTO objects using the
   relocatable object file. (`D146778 <https://reviews.llvm.org/D146778>`_)

Could be worth adding
* ``--save-temps --lto-emit-asm`` now derives ELF/asm file names from bitcode file names. ld.lld --save-temps a.o d/b.o -o out` will create ELF relocatable files `out.lto.a.o`/`d/out.lto.b.o` instead of `out1.lto.o`/`out2.lto.o`. (`#78835 <https://github.com/llvm/llvm-project/pull/78835>`_)
