C++20 RISC-V RV32/64/128 userspace emulator library

Project mention: Ask HN: Looking for a project to volunteer on? (November 2023) | news.ycombinator.com | 2023-11-02

This is a C++ RISC-V emulator that focuses on isolating a single process, aka userspace emulation. I am currently working mostly on binary translation, and recently I have made a push to move it from experimental state to fully supported. Another experimental feature is embedding libtcc and using that for binary translation. It is fairly fast to compile, and gives decent speedups. The challenge is what to do now that (perhaps) some low hanging fruits have been picked.

A non-sampling profiler purpose built to measure and optimize performance of C++ low latency/real time systems

Project mention: Google/orbit – C/C++ Performance Profiler | news.ycombinator.com | 2024-02-11

Can anyone suggest a good non-sampling profiler for low latency apps? The only one I can think of is https://github.com/morganstanley/Xpedite but it's not even clear that it is being maintained anymore.
