Find all the places that simplify RTL and make them use simplify-rtx.c That is a good question but I don't have a good answer. If you are interested in one of those, I recommend writing to gcc@xxxxxxxxxxxx The unstated goal of number 1 is to speed up the generated code in insn-recog.c. That would be a nice small improvement in compilation time. Take a look at insn-recog.c and see what you come up with. Number 2 is a rather hairy problem: getting reorg.c to use things like cfglayout mode and the dataflow information, rather than its own private resource management code in resource.c. This is only mildly interesting as most popular targets do not use the code in reorg.c. I'm not sure what the status of number 3 is. I hope that there aren't too many places which are not using simplify-rtx.c anyhow. The list of open projects gets cleaned up occasionally but not very often. There are a lot of good ideas on http://gcc.gnu.org/wiki/ in the links under "Improving GCC". Ian
