The memory allocator is a very important component, which significantly affects both performance an stability of the game. The purpose of is to allow the allocator to be developed independently on the application, allowing both Bohemia Interactive and co
of using native calls like 'malloc' or 'free' we're going to use a custom memory allocator that will do this for us but in a more efficient way. The goal, then, is to understand how the most common allocators work, what they offer and compare them to see which one performs better...
We present MemBrush, a new tool to detect memory allocation and deallocation functions in stripped binaries with high accuracy. We evaluated the technique on a large number of real world applications that use custom memory allocators. We demonstrate that MemBrush can detect allocators/deallocators...
Custom dynamic memory allocator using the segragated fit mechanism Built this as part ofSiKV, that I am also working on, but I felt the need to have it on a separate repo to work on it independently -- as I add more features in the future ...
