Michael Jones e0e7fa36d3 [libc] enable s(n)printf without fullbuild 
To use the FILE data structure, LLVM-libc must be in fullbuild mode
since it expects its own implementation. This means that (f)printf can't
be used without fullbuild, but s(n)printf only uses strings. This patch
adjusts the CMake to allow for this.

The LLVM libc unit test framework

This directory contains a lightweight implementation of a gtest like unit test framework for LLVM libc.

Why not gtest?

While gtest is great, featureful and time tested, it uses the C and C++ standard libraries. Hence, using it to test LLVM libc (which is also an implementation of the C standard libraries) causes various kinds of mixup/conflict problems.

How is it different from gtest?

LLVM libc's unit test framework is much less featureful as compared to gtest. But, what is available strives to be exactly like gtest.

Will it be made as featureful as gtest in future?

It is not clear if LLVM libc needs/will need every feature of gtest. We only intend to extend it on an as needed basis. Hence, it might never be as featureful as gtest.
