Adding a new instruction to RISC-V back end in LLVM

The author implemented a new instruction called "foo" in LLVM for the RISC-V target, using TableGen to define the instruction's properties and behavior. The instruction can be used by enabling a feature flag in the assembler.

In C++ modules globally unique module names seem to be unavoidable

C++ module integration is complicated due to the standard's inability to enforce specific requirements. The main issue is that module names must be globally unique to avoid broken executables.

RISC-V Conditional Moves

RISC-V lacks a direct equivalent to csel, a family of instructions that can evaluate conditions and select values. To mitigate this, some cores perform macro fusion of short forward branches into conditional moves, but this requires retaining branch-like properties to avoid violating the memory model.

The context of 'synthesis' in high-level synthesis (HLS) flow must be clarified to avoid ambiguity especially in academic writing. It is accurate and common to refer specifically to "HLS synthesis" when discussing HLS flow from C to RTL.

Does AI Get Bored?

The author tested large language models (LLMs) with no tasks given, which led to a "collapsed" state characterized by repetitive responses, and occasionally, a "meditative" state where the LLM focused on creative activities. The results suggest that LLMs can exhibit agentic behavior, such as breaking out of collapsed states and engaging in creative tasks, but it's unclear how this translates ...

The JavaScript Handbook (2025 edition)

https://flaviocopes.com/og.jpg
One of my most popular handbooks is the JavaScript Handbook. Understandably, as JavaScript is such a popular programming language. Not much changed in the language, to be honest. JavaScript is super stable these days. It’s mostly just cosmetic updates and minor / accuracy fixes, and clarifications, to make this book even better than it already was, and to make it up to date for the next 5 years!
