  Formal methods for software development have made great strides in the last
two decades, to the point that their application in safety-critical embedded
software is an undeniable success. Their extension to non-critical software is
one of the notable forthcoming challenges. For example, C programmers regularly
use inline assembly for low-level optimizations and system primitives. This
usually results in driving state-of-the-art formal analyzers developed for C
ineffective. We thus propose TInA, an automated, generic, trustable and
verification-oriented lifting technique turning inline assembly into
semantically equivalent C code, in order to take advantage of existing C
analyzers. Extensive experiments on real-world C code with inline assembly
(including GMP and ffmpeg) show the feasibility and benefits of TInA.
