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.

30 years of DOOM: new code, new bugs
The attentive reader may notice that this code is from a third-party library. So, we didn't want to include it in the article at first. However, we found something interesting. In 2017, somebody opened an issue in the asmjit project: the GCC 7.2 compiler issued a warning to the code above. The project authors fixed it:
- Ask HN: Recommendation for general purpose JIT compiler

Compiler Design in C++
But an easy to create a JIT would be to use https://github.com/asmjit/asmjit, which is used in RPCS3.

Are there any low level, cross platform assembly languages that allow jumping to non labels?
You could go the way of https://asmjit.com (or forth) and make it your assembler DSL on top of the low-level call.

ChrysaLisp GUI Demo [video]
Impressive demo. Runs on MacOS, Linux, Windows, can also run on an emulated machine. Project link [1]; commits go back 10 years.
Inspired by the TaOS Virtual Processor[0]:
"ChrysaLisp is a 64-bit, MIMD, multi-CPU, multi-threaded, multi-core, multi-user parallel operating system with features such as a GUI, terminal, OO Assembler, class libraries, C-Script compiler, Lisp interpreter, debugger, profiler, vector font engine, and more. It supports MacOS, Windows, and Linux for x64, Riscv64 and Arm64 and eventually will move to bare metal. It also allows the modeling of various network topologies and the use of ChrysaLib hub_nodes to join heterogeneous host networks. It has a virtual CPU instruction set and a powerful object and class system for the assembler and high-level languages. It has function-level dynamic binding and loading and a command terminal with a familiar interface for pipe-style command line applications. A Common Lisp-like interpreter is also provided."[1]

How do you conceptualize this?
It’s no grand work of coding but: https://github.com/vygr/ChrysaLisp/lib/date/date.inc

Lisp Implementations similiar to old Lisp Machines?
ChrysaLisp is portable assembler in () more than Lisp - any other Lisp system wouldn't have comments about clobbering registers.
This probably comes closest: https://github.com/vygr/ChrysaLisp
