LLD, LLVM’s New Linker, Coming to LLVM 4

by Sergio De Simone on  Feb 21, 2017

LLD, which touts great performance improvements over GCC ld, will be included in LLVM 4 rc1 and enabled by default. Although the new linker is already able to build a running FreeBSD/amd64 base system, its inclusion in LLVM is still experimental and could be set back in rc2 if it causes problems.

MIT Extended LLVM IR to Enable Better Optimization of Parallel Programs

by Sergio De Simone on  Feb 06, 2017

Researchers at MIT have been working on a fork of LLVM to explore a new approach to optimizing parallel code by embedding fork-join parallelism directly into the compiler’s intermediate representation (IR). This, the researchers maintain, makes it possible to leverage most of the IR-level serial optimizations for parallel programs.

Swift Might Not Be As Fast As Apple Claims It To Be: First Benchmarks

by Sergio De Simone on  Jun 11, 2014 2

Performance is one of the benefits that Apple claims its new Swift programming language should bring to OS X and iOS developers, and being in beta hasn't prevented independent developers from running benchmarks and reporting their findings. Perhaps unsurprisingly these show that in some cases Swift performance is not yet satisfactory.

Debate: Do We Need a Universal Web Bytecode?

by Abel Avram on  May 22, 2013 11

Is a universal web bytecode worth the trouble creating it? Is LLVM the solution? Which is better at running native code in the browser: Mozilla asm.js or Google PNaCl? This article contains opinions expressed on the web on these issues.
