[LLVMdev] Why are LLVM libraries enormous?

Why? I'd never checked, but I always assumed the LLVM JIT was much
larger than 3.4 MB.
For comparison:
[rnk at tamalpais google3]$ du -h /usr/lib/gcc/x86_64-linux-gnu/4.4/cc1plus
10M /usr/lib/gcc/x86_64-linux-gnu/4.4/cc1plus
[rnk at tamalpais google3]$ du -h `which python2.6`
2.5M /usr/bin/python2.6
It seems reasonable that a JIT compiler with optimizers would weigh in
somewhere between an interpreter and a full C++ compile...

> Why do you care about the size of library files?
I assumed dynamic libraries and static libraries were similar in size, but I just checked some of my own static libraries and they are indeed much larger than the executables they compile to. Sorry, it just never occurred to me that they would be much different.

klibc: support llvm's lld
Clang that we have in google3 started emitting relocations that
our outdated binutils ld doesn't support. In an effort to switch
userspace to use llvm's ld, let's teach klibc some ld.lld quirks.
