C++ X64

Open-source C++ projects categorized as X64

Top 16 C++ X64 Projects

  1. x64dbg

    An open-source user mode debugger for Windows. Optimized for reverse engineering and malware analysis.

    Project mention: Debugging bugs in x64dbg debugger. Step out to GUI | dev.to | 2024-11-19

    Several months have passed since the last part was posted. Maintainers of x64dbg have continued to improve its functionality. They also opened a task to update the development tools. So in this post, we will continue the analysis based on commit f518e50 code and, where possible, we'll compare it with the commit 9785d1a, which is accurate at the time of writing.

  2. InfluxDB

  3. simdjson

    Parsing gigabytes of JSON per second : used by Facebook/Meta Velox, the Node.js runtime, ClickHouse, WatermelonDB, Apache Doris, Milvus, StarRocks

    Project mention: Make Ubuntu packages 90% faster by rebuilding them | news.ycombinator.com | 2025-03-18

    I think parsing once into a faster format (sqlite3 or parquet) would be more beneficial.

  4. oneDNN

    oneAPI Deep Neural Network Library (oneDNN)

    Project mention: Exploring biphasic programming: a new approach in language design | news.ycombinator.com | 2024-07-02

    I'm going to hijack the mention of ML to share xbyaku, a c++ library presenting a DSL for assembling machine code at runtime (useful for JIT).

    It's used by some of the pytorch back ends.

    https://github.com/herumi/xbyak

    Example use: https://github.com/oneapi-src/oneDNN/blob/main/src/cpu/aarch...

    I learned about these through a blog post about speeding up pytorch on ARM: https://pytorch.org/blog/optimized-pytorch-w-graviton/

  5. xray-16

    Improved version of the X-Ray Engine, the game engine used in the world-famous S.T.A.L.K.E.R. game series by GSC Game World. Join OpenXRay! ;)

    Project mention: OpenXRay: Reviving the S.T.A.L.K.E.R. Legacy | dev.to | 2025-05-19
