I will try asking on the gcc list about that. I see. I also expect that the experts have some idea for this issue. > I think it would be a bit too much checking out each individual pattern. I don't think that it's too much. Those numbers can be easily collected for CSiBE. If your patterns are named, you could simply add "-dap -save-temps" to the compiler option which is specified when ruining CSiBE's create-config and then get the occurrences of testsi_6, for example, with something like grep "testsi_6" `find . -name "*.s" -print` | wc -l after running the CSiBE size test.
