LLVM 2.4 is now available, and like every very active project, a bunch of new stuff has arrived (see the release notes for a detailed description). The same is true for the Mips back-end. I talked about mips+llvm in old posts, they highlighted some of the ABI issues both from EABI and O32 stuff. A lot has changed since those posts, and here is a summary of what has been accomplished:

• Little endian support
• EABI is fully implemented
• Floating point support
• Support for allegrex core and its intrinsics
• Improvements to the O32 ABI.

I’m the creator and current Mips back-end mainteiner, and I implemented those feature as a Google Summer Of Code 2008 project. To a more detailed description, here is the svn commit log for the Mips back-end  -  I filtered out all commits not directly related to mips improvement). Although it has grown a lot since June, it still a experimental back-end and there is much to be done.
