If Marc (or anyone) provides us with a test case for the performance regression - for instance, the set of files produced by running gcc -E over all of the openbsd kernel, which is what Andrew meant - then we can find out why the compiler is slower, and fix it. We do have our own test cases for compile time, and they have been being fixed (mostly by Jan Hubicka) but we don't know that this will help you. zw
