André Maroneze on 17 June 2020

The analysis scripts provided with Frama-C, which have been mentioned in this blog several times, are now documented in the Frama-C User Manual. This should provide a more complete and up-to-date experience concerning these scripts. Faster iterations with daily Frama-C snapshots Deploying analysis scripts usually required very long iteration times:...

Frama-C has a somewhat obscure plug-in called Obfuscator, whose original purpose was to help industrial users give the Frama-C developers enough information about confidential use cases, for debugging and optimizations. However, sharing proprietary code is never easy: is the obfuscation good enough? Are there legal issues involved? Is it worth...

One of the new features in Frama-C 18 (Argon) is the annotation @loop unroll, used by the Eva plug-in to replace and improve upon the usage of slevel for semantically unrolling loops. This new annotation is more stable, predictable, and overall more efficient. In this post we present the annotation...

A recurring subject when using Frama-C, especially intriguing for newcomers, is how to reach the stage where parsing of a realistic code base (as in, one that uses external libraries and compiles to different architectures) succeeds. This post will show a bit of the depth involved in the subject, presenting...
