These are in-progress notes for the upcoming LLVM 3.3 release. You may prefer the LLVM 3.2 Release Notes.
This document contains the release notes for the LLVM Compiler Infrastructure, release 3.3. Here we describe the status of LLVM, including major improvements from the previous release, improvements in various subprojects of LLVM, and some of the current users of the code. All LLVM releases may be downloaded from the LLVM releases web site.
For more information about LLVM, including information about the latest release, please check out the main LLVM web site. If you have questions or comments, the LLVM Developer’s Mailing List is a good place to send them.
Note that if you are reading this file from a Subversion checkout or the main LLVM web page, this document applies to the next release, not the current one. To see the release notes for a specific release, please see the releases page.
We’ve added support for AArch64, ARM’s 64-bit architecture. Development is still in fairly early stages, but we expect successful compilation when:
Some additional functionality is also implemented, notably DWARF debugging, GNU-style thread local storage and inline assembly.
We’ve continued the work on the loop vectorizer. The loop vectorizer now has the following features:
The R600 backend was added in this release, it supports AMD GPUs (HD2XXX - HD7XXX). This backend is used in AMD’s Open Source graphics / compute drivers which are developed as part of the Mesa3D project.
A wide variety of additional information is available on the LLVM web page, in particular in the documentation section. The web page also contains versions of the API documentation which is up-to-date with the Subversion version of the source code. You can access versions of these documents specific to this release by going into the llvm/docs/ directory in the LLVM tree.
