Solved bug found by Teme about asserts.

Previously assert expression containing -> would lead to unnormalized ite. Now each expression within the assert is normalized and may bind new node equations.
This could be later optimized but is working now.

13fa31c2 12/10/2014 11:15 AM Pierre-Loïc Garoche

Revert the commit 384 by Xavier: adding dirname to the source_name introduced a bug: the .h file is empty!!! Strange behavior.

5d8ddbf7 12/10/2014 11:14 AM Pierre-Loïc Garoche

Added an install target in the src folder

c825868a 12/09/2014 02:03 PM Xavier Thirioux

added a new option -print_reuse that prints clock disjoint variables and reuse policy.
useful for debugging and carrying correctness proofs to the C code level.
non trivial result only when option -O 3 or above is activated.
