Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Project Oberon the Design of an Operating System, a Compiler, and a Computer Pdf
this sort of exists at https://github.com/cksystemsteaching/selfie
> Selfie is a self-contained 64-bit, 12KLOC C implementation of: (...) a tiny (...) subset of C called C Star (C) (...) to a tiny (...) subset of RISC-V called RISC-U[;] a[n] (...) emulator (...) that executes RISC-U code[;] (...) a (...) hypervisor (...) that provides RISC-U virtual machines*
so they have an instruction set architecture, a compiler, and an operating system, though it's much simpler than xv6. because the instruction set is a subset of risc-v you can run its code on actual risc-v hardware (or qemu-system-riscv), but presumably you could also design risc-u hardware in verilog that was simpler than a full implementation of rv64i with whatever extensions the hypervisor needs
- Best book on writing an optimizing compiler (inlining, types, abstract interpretation)?

- An educational software system of a tiny self-compiling C compiler, a tiny self-executing RISC-V emulator, and a tiny self-hosting RISC-V hypervisor.

Supporting BFLOAT16 in ISO_Fortran_env: not recommended
It is great to know that LLVM Flang supports BFLOAT16!
I look forward to trying it in my project ( http://www.libprima.net ), although LLVM Flang is not ready to use last time I tried.
As a side note, the Classic Flang ( https://github.com/flang-compiler/flang ) does not support kind = 3.

Best book on writing an optimizing compiler (inlining, types, abstract interpretation)?
I think a lot of this material is in research papers and code. Take a look a MLTon or Clang Fortran
- Any updates on Flang?

Accidentally quadratic: When Python is faster than C++
I feel like the would have to, if they were to produce a remotely competitive compiler. That's why I'm hoping NVidia's Flang[1] efforts will lead to this aspect of LLVM being cleaned up.
