Note that while I appreciate the benchmarking very much, not
providing details on which SPEC tests regress in compile time is bad.
Can you manually identify the worst offender, ideally by file? Or is it
just overall regressing?
I can guess it is mostly overall regression. Of course there is always
worst offender. I could find it but it will take some time which
unfortunately I don't have next 2 weeks. Sorry for that. Even such
benchmarking takes a lot of time.
I do such bechmarking because I am worried more about missed code
regressions for now (I think that easy significant compile time
improvement is not possible anymore). After the merging such code
quality comparison will be impossible and it will be hard to say what
is missed because of the new df code. And I see that people (mostly
Seongbae) doing a good job fixing code regressions. I really
appreciate that because I know how hard to fix them for SPEC2000.
