I wanted some mechanical way to compare the output of dejagnu runs between releases, etc. I asked a few people at the GCC Summit last year what they used or knew about. Not much came to light, so I ended up writing something of my own.
It's a shell script I've been using on Linux with only trivial changes since December. The one tricky part was dealing with lines in the results file that are identical. I made the rash assumption that the relative order wouldn't change between runs and that seems to hold. The script works well although it isn't blazingly fast. My current version is attached. If others find it useful I can contribute it. Comments and suggestions are welcome. Typical invocation is something like: dg-cmp-results.sh -v "" gcc-20060328.sum gcc-20060510.sum |less for the first variation in the files, or dg-cmp-results.sh -v arm-sim gcc-20060328.sum gcc-20060510.sum |less for a specific variation.
