[LLVMdev] Google Summer of Code proposal: Adding memory safety checks to the LLVM bitcodes
...nd identifiers across function calls in order to have a precise analysis, as described in the paper [1]. I do not plan to couple my analysis with the interval domain, but, if the LLVM community judge that it should be done, than I can implement my algorithm after the pentagon domain, proposed by Logozzo and Fahndrich in 2010 [2]. The pentagon domain is a different approach to get an analysis that is overflow resilient. It combines the interval domain {-inf, ..., -1, 0, 1, ... +inf} with the "less-than" domain. If some variable is bound to an interval like [l, u], where l -inf and u <...

[LLVMdev] Google Summer of Code proposal: Adding memory safety checks to the LLVM bitcodes
...w/underflow into account? No. The less-than lattice only reports if a variable is less than another, assuming that your lattice is {-inf, ... -2, -1, 0, 1, 2, ... +inf}. But I know of another lattice that takes overflows into consideration. It is called the Pentagon domain, and it was published by Logozzo and Fahndrich in the paper [1]: [1] Francesco Logozzo, Manuel Fähndrich: Pentagons: A weakly relational abstract domain for the efficient validation of array accesses. Sci. Comput. Program. 75(9): 796-807 (2010) Pentagons combine the less-than lattice with the interval lattice to have an analysis...

[LLVMdev] Google Summer of Code proposal: Adding memory safety checks to the LLVM bitcodes
Dear LLVMers, My name is Raphael Ernani, and I am doing my MsC at the Federal University of Minas Gerais, Brazil. I have been using LLVM for a while, and I would like to participate in this year's Summer of Code. One particular idea, in your "open projects" page caught my eye, and I decided to write a proposal about it. The line that I liked in the page was "Create an LLVM
