You're not kidding. This is something we need desperately, some time
last year. JIT compilers really are different to all other userspace
programs in this regard: we really do need to know exact models,
pipelines, and so on, in order to generate best code. In some cases
we even need to minor CPU versions to work around bugs. We really
don't want to have to parse /proc/cpuinfo.
