The Blackfin ELF compiler requires the user to explicitly select a CPU target else it will fail: bfin-elf-gcc: error: no processor type specified for linking Select the sim target for these tests since we should (hopefully) have access to the simulator. At least, it's more likely than having access to a real development board. This makes the pass/fail numbers increase by a lot: -# of expected passes 398 -# of unexpected failures 6 +# of expected passes 587 +# of unexpected failures 109 It looks like the vast majority of new failures are due to our omission of COPY relocations: /* Bfin does not currently have a COPY reloc. */ if ((h->root.u.def.section->flags & SEC_ALLOC) != 0) { _bfd_error_handler (_("the bfin target does not currently support the generation of copy relocations")); return FALSE; } There doesn't seem to be a way to easily disable tests that cause copy relocations though, lets just take the hit for now. * testsuite/config/default.exp [bfin*-elf*] (gcc_B_opt): Append -msim.
