; This test checks that the gold plugin does not attempt to use the bitcode
; in the .llvmbc section for LTO.  bcsection-lib.o calls a function that is
; present the symbol table of bcsection.bco, but not included in the embedded
; bitcode.  If the linker were to use the bitcode, then the symbols in the
; symbol table of bcsection.bco will be ignored and the link will fail.
