This document was originally written several years ago. At the time I was working as an execution core verification engineer at Arm. The following points are coloured heavily by working in and around the execution cores of various processors. Apply a pinch of salt; points contain varying degrees of opinion.

It is still my opinion that RISC-V could be much better designed; though I will also say that if I was building a 32 or 64-bit CPU today I'd likely implement the architecture to benefit from the existing tooling.

Mostly based upon the RISC-V ISA spec v2.0. Some updates have been made for v2.2

Original Foreword: Some Opinion

The RISC-V ISA has pursued minimalism to a fault. There is a large emphasis on minimizing instruction count, normalizing encoding, etc. This pursuit of minimalism has resulted in false orthogonalities (such as reusing the same instruction for branches, calls and returns) and a requirement for superfluous instructions which impacts code density both in terms of size and

Step-by-step instructions to build Emacs for Windows 64 bit with MSYS2 and MinGW-w64. Now `native-comp` supported.

Build Emacs-w64 with MSYS2/MinGW-w64 with Native Compilation

Instructions are modified from emacs-w64 Wiki page by zklhp. Many thanks for sharing!

  1. Download the latest MSYS2 from this download page.

  2. Install MSYS2 to, for example, C:\msys2 (make sure no space in path to avoid unwanted problems).

  3. Optionally prettify the MSYS2 console mintty with ~/.minttyrc to make it more pleasing to eyes. Thanks to this awesome theme!
