14 ; We can't read symbols that are set by `module asm` in the bitcode's symbol table.
15 ; LTO compiles only f.ll, b.ll, and m.ll without q.ll due to missing reference to `q_asm` in f.ll.
16 ; However, later `q_asm` appears in the resulting object for `f.ll`, which triggers resolving
17 ; a ODR symbol `q_odr` from `q.ll,` as opposed to one expected from `b.ll`.
18 ; As a result, we have invalid relocation for `q_odr` as `q.ll` is neither compiled, nor linked.
20 ; CHECK: error: The pending prevailing symbol(_q_odr) in the bitcode file({{.*}}libb.a(b.o)) is overridden by a non-native object (from bitcode): {{.*}}libq.a(q.o)
