Clang Standard C Library

Question

I work with an embedded environment in which there is no operating system or file system. I am looking for a minimal C library with at least standard versions of stdio, stdlib and math, although it would be better.

The library needs to be ported, as there is definitely no implementation for this architecture. The compiler for this architecture uses LLVM, so the library should be able to build with clang.

Can anyone suggest a good candidate? I already looked at some of them:

• newlib http://www.sourceware.org/newlib/ (not created using clang AFAIK)
• uClibc http://www.uclibc.org/ (not created using clang)
• pdclibc http://pdclib.e43.eu/ (no math support)
