I've been focusing on kernel profiling, when I should also be thinking
about user profiling. With these changes, will gprof be able to profile
the output of 32-bit sparc apps? With NetBSD/sparc64, are you running
all user apps at 64-bit? If you lose all userland profiling, this seems
like a serious compatibility issue.
