[PATCH 0/4] Add lto and none-lto input support for ld -r

[H.J. Lu]

We generate a mixed ET_REL object with ld -r from non-IR ET_REL objects
and IR ET_REL objects, which contains IR sections and a special non-IR
section.  When generating ET_EXEC or ET_DYN output, linker extracts an
non-IR ET_REL object from the special non-IR section in the mixed ET_REL
object and adds it to the list of linker inputs.

H.J. Lu (4):
  ld: Add lto and none-lto input support for ld -r
  Add test for nm on mixed LTO/non-LTO object
  Don't check the plugin target twice
