Source is not simple and clang was modified. Anyway, If I cannot resolve
with clang 3.6 (old version for ARM), I am planning to build/execute full
sources with 3.8.x (or latest commit number).

Do you mean that you could successfully build and run some unit-tests with
-O3 flag + latest revision (e.g., LLVM rev 273084)?

It's Ubuntu/ARM 14.04 distribution.

Don't try to avoid pain if you fail.

you can gain a lot by giving your best.
