Some thoughts on LLVM vs. libjit - Eli Bendersky's website
Having recently completed a series of articles on using libjit and understanding how it works, I couldn't stop comparing it to LLVM inside my head. This is hardly surprising, since LLVM has been a significant part of my professional life for the past 3.5 years, and will remain in this position in the foreseeable future. So this post is some unfiltered thoughts on libjit and LLVM - what's similar,

Runtime Codegeneration in Haskell: Harpy vs. LLVM
Currently, I’m writing on my master thesis. The resulting prototype is called MateVM which is a method-based Java Just-In-Time Compiler, written in Haskell. Although, it’s a rather low-level application, Haskell is a perfect match (well, that’s my opinion ;-)). Anyways, for dynamic code generation we use Harpy, which is only available for x86 at the moment (no PowerPC sigh). People ask us, why we
LLVM 3.0 Type System Rewrite
One of the most pervasive IR (and thus compiler API) changes in LLVM 3.0 was a complete reimplementation of the LLVM IR type system. This change was long overdue (the original type system lasted from LLVM 1.0!) and made the compiler faster, greatly simplified a critical subsystem of VMCore, and eliminated some design points of IR that were frequently confusing and inconvenient.
