Morgan Wilde talks with SE Radio's Jeff Meyerson about the LLVM compiler toolchain. They begin with a discussion of how a compiler works and how compiled code executes against different processor architectures. Using the JVM as a model for interoperability, they move on to how LLVM is a system that optimizes an intermediate representation (IR), which is similar to the Java bytecode: every programming language that compiles down to IR can leverage the same optimizations of that IR. The conversation concludes with a discussion of applications of LLVM and the future of the ecosystem.
