As we are on the topic of SPEC and test-suite: The SPEC running Makefiles in the test-suite do not come close to proper SPEC runs. They only ever run 1 input while SPEC often supplies multiple different inputs. They are good as “smoke” tests but do not necessarily reflect the changes in a real ref run.
If you need spec-ref numbers then I would recommend to use the runspec tool that comes with SPEC or the test-suite/LNTBased stuff (lnt runtest nt —spec-with-ref I believe). I’m also currently integrating proper SPEC support into the new cmake/lit style of the test-suite which already properly handle SPEC95 and SPEC2000 but the SPEC2006 part isn’t finished yet.
