One of the platforms I use has an 800MHz ARM processor.  Building LLVM =
(even a release build with asserts disabled and with all of the =
cross-compile targets disabled) is an overnight job.  On my main laptop, =
a release build of LLVM takes about 5 minutes.

Please don't assume that just because fast computers exist that they are =
the only things people are using.  A lot of the more interesting =
platforms these days are significantly slower.
