Hmm. Some things that help with this for me are to:
1) Compile with -j12 (or lower, depending on your hardware spec)
2) Compile with "cd compiler && make stage=2" to only build the stage
2 compiler (if this isn't already happening). Make sure the stage 1
compiler is built with optimisations! (I use the stage2devel
configuration, which already does this)

This reduces compile times to a few minutes for me. Still tedious, but
not too bad.

Thanks. Doing this reduces compilation time to about 30s, but unfortunately my pass is not updated (even though it is compiled). I have to do 'make stage=2' at the root directory, not inside compiler. This brings compilation time to 1m10s (which is still better than what I was doing), but I really don't know what would need building outside the compiler directory...

As an aside, is there any hope of using SYB in the core pass? As a generic programmer I quickly get tired of traversing the entire AST when I want just a few changes in specific places...

Thanks,
Pedro

Hope that helps,
