They are currently implicit because TargetMachine::shouldAssumeDSOLocal implies dso_local. For such function declarations, clang -fno-pic emits the dso_local specifier. Adding explicit dso_local makes these tests align with the clang behavior and helps implementing an option to use GOT indirection when taking the address of a function symbol in -fno-pic (to avoid a canonical PLT entry (SHN_UNDEF with non-zero st_value)).
