GitHub - metacraft-labs/codetracer: CodeTracer is a user-friendly time-traveling debugger designed to support a wide range of programming languages.
Compared to traditional debuggers, CodeTracer gives you two major superpowers: Once you capture a bug in a recording, consider it squashed! Bugs that are hard to reproduce can be painful to fix — you’ve surely been there. Once such a bug is captured with CodeTracer, you'll rarely need more than 30 minutes to track it down! This is largely a consequence of the next superpower: Most bugs are easily

Hazard3 is a 3-stage RISC-V processor, implementing the RV32I or RV32E instruction set and the following optional extensions: M: integer multiply/divide/modulo A : atomic memory operations, with AHB5 global exclusives C: compressed instructions Zicsr: CSR access Zilsd: load/store pair instructions Zba: address generation Zbb: basic bit manipulation Zbc: carry-less multiplication Zbs: single-bit ma
GitHub - google/orbit: C/C++ Performance Profiler
This project is not maintained by Google engineers anymore at this point. Orbit, the Open Runtime Binary Instrumentation Tool is a standalone native application profiler for Windows and Linux. It supports native applications written in languages such as C, C++, Rust, or Go. Its main purpose is to help developers identify the performance bottlenecks of a complex application. Orbit can be also used
