There already exist makefiles to build them in the LLVM test-suite and I had hope I could use the test-suite to create the bitcode files. It looks like the SPEC makefiles contain rules to build and then run the benchmarks with the interpreter but I could not figure out how to make this happen using the LNT tool. I tried to directly run the makefiles instead of using LNT but it just caused a lot of terrible errors.

  You can make SPEC just build those benchmarks, right? My point is if you *just*
want get those bitcode, then build those benchmarks rather than running them. :)
