OK, some results from Andreas came. The 3rd liveness pass costs about 1% of compilation time and brings noticeable speedups to C++ code only (eon, stephanov) about 1%. We definitly need to replace heuiristics in GCC by proper analyzers, so perhaps we can make people to wait 1% longer, or we can speed up liveness. I've posted question about it. If converison adds about 3 points to specs, this is good comparisons to 2-3 points brought by double test pass. Lets re-measure it, it can be interesting to see whtehr bootstrap time changes. GCC has plenty of oppurtunities for double test converison. So for now I will study and see whether someone repsponds to the posts. Would be cool to measure behaviour on non-x86 platform. Need to set up something...
