Hi, so here's something more of my patch queue. It adds the facility to merge also other trees than types over compilation unit borders. This specific patch only deals with STRING_CST and INTEGER_CST nodes. Originally I used that place for merging declarations, hence the naming of some variables. That needs to wait for adjustments of the cgraph/varpool streamer.
On building cc1 the overall numbers of trees that stay around after all global sections are streamed in goes down from 620818 to 598843 trees, overall saving 1 MB (out of 76 MB for just the trees). Not much, but hey... Regstrapping on x86_64-linux in progress. Okay for trunk? Ciao, Michael.
