GHCcold

GHCcold is a term that emerged within online communities, particularly associated with discussions around the Haskell programming language and its primary compiler, the Glasgow Haskell Compiler (GHC). It refers to a hypothetical or perceived state where the GHC compiler is considered to be performing poorly in terms of speed, efficiency, or responsiveness. This perception can arise from various factors, including slow compilation times, excessive memory usage during compilation, or the generation of inefficient machine code.

The concept of "GHCcold" is not a formal technical specification or a recognized bug category. Instead, it's a colloquial expression used by developers to describe their subjective experience when encountering performance issues with the compiler. Users might employ this term when they feel that GHC is taking an unusually long time to compile their code, especially for large projects or when making minor changes.

Discussions around "GHCcold" often involve sharing personal anecdotes, comparing build times, and seeking solutions or workarounds. These conversations can also lead to investigations into specific compiler optimizations, dependency management, or hardware configurations that might be contributing to the perceived slowness. While the term itself is informal, the underlying issues it represents are genuine concerns for developers aiming for efficient development workflows.
