Issue created Jun 02, 2014 by Jochen Burghardt@burghardt

"assigns \nothing \from ..." unrecognized, although admitted by ACSL grammar

ID0001794: This issue was created automatically from Mantis Issue 1794. Further discussion may take place here.


Id Project Category View Due Date Updated
ID0001794 Frama-Clang Kernel public 2014-06-02 2015-02-20
Reporter Jochen Assigned To virgile Resolution fixed
Priority normal Severity minor Reproducibility always
Platform - OS xubuntu-cfe13.10 OS Version -
Product Version Frama-C Neon-20140301 Target Version - Fixed in Version -

Description :

Output from "frama-c from03.c" is: from03.c:5:[kernel] user error: unexpected token '\from'

Output after reaminig to "from03.cpp": from03.cpp:5:23: Expecting ';' after assigns

However, according to the manual "ACSL Version 1.8 --- Implementation in Neon-20140301", fig.2.22, p.63, it is valid syntax.

I could image that such clauses can make sense, e.g. to specify that a function writes a certain variable to stdout; in security applications it may be undesirable to express such issues. (If I'm wrong here, the above error message wouldn't be an issue.)
