It's not LOC.
It's 52 targets with a bunch of subtargets against a compiler that so
far can't tell the difference between a Pentium 2 and a Pentium 3.
Redoing all the backends for LLVM is a huge amount of work. Think
about the S/390 for example, or AMD64, Itanium, etc. Those are not
targets you just rewrite a good backend for in a matter of weeks or
months.
