Comment (by ken@…):

 Various comments in mozilla bug reports suggest that, at least for the
 next few firefox releases, the latest version of rust will be needed (the
 language is still developing, they will want the additions) and therefore
 rust will probably need to be upgraded for each new firefox major version.

 I've experimentally installed a cut-down llvm-3.9.1 (only the basic part,
 only for host cpu, but with FileCheck) in /opt/llvm3 on my underpowered
 test machine (the AMD Kaveri) so that I can decide if that is likely to be
 worthwhile on a non-high-end machine.

 Unfortunately, my scripted build of rust, with the system llvm-3 and the
 tests, took over 47 minutes.  When I looked at top while rust was
 building, it only ever seemed to use 100% or 200% CPU instead of 400%. I
 need to do more testing/measuring on that machine once the build is
 completed.
