Hi LLVM Friends, Fans, Followers and Fanatics,

LLVM 2.6 is live! You can download it here:
http://llvm.org/releases/  and read about it here:
http://llvm.org/releases/2.6/docs/ReleaseNotes.html

This release includes approximately 6 months of development that provide
major enhancements and new features over the LLVM 2.5 release.  This
includes significantly better X86-64 code generation, link-time
optimization support for ELF systems (with 'gold' linker), new code
generators for the MSP430, SystemZ, and BlackFin architectures, support
for multithreaded code generation and optimization, OProfile integration
for the JIT, support for SSE 4.2, ARM V7 support (including Thumb2 and
NEON), Ada2005 bindings, many improved optimizations, bug fixes, and
extensions and enhancements to the runtime API.  Please see the release
notes for more details.

A major highlight of the LLVM 2.6 release is the first public release of
the Clang compiler (http://clang.llvm.org), which is now considered to
be production quality for C and Objective-C code on X86 targets.  Clang
produces much better error and warning messages than GCC
(http://clang.llvm.org/diagnostics.html) and can compile Objective-C
code 3x faster than GCC 4.2 (http://clang.llvm.org/performance.html),
among other major features.

In addition to Clang, the LLVM project has grown a number of new LLVM
sub-projects, including:
- compiler-rt: Compiler runtime library (http://compiler-rt.llvm.org/)
- KLEE: Symbolic Analysis & Test Case Generator (http://klee.llvm.org/)
- DragonEgg: "llvm-gcc" plugin for GCC 4.5 (http://dragonegg.llvm.org/)

This release also includes the early start of a new "llvm-mc" project
(http://llvm.org/releases/2.6/docs/ReleaseNotes.html#mc), which aims to
auto-generate a suite of assembler, disassembler, and other machine code
technology from the LLVM target descriptions.

One of the things I'm really excited to see is the number of external
projects that are applying LLVM technology in interesting new ways.  The
release notes lists two Ruby implementations (Rubinius and MacRuby), the
Pure language, the LLVM D Compiler, the Roadsend PHP compiler, Unladen
Swallow (Python) and LLVM-Lua.  These projects show an amazing breadth
of different languages adopting LLVM as their shared optimization,
code generation, and JIT technologies (depending on the project).

Besides open source projects, there are a number of commercial
organizations applying LLVM in innovative new ways
(http://llvm.org/Users.html), and LLVM is being used for a wide range
of research projects published at the top academic conferences and
journals (http://llvm.org/pubs/).  It is truly exciting to see what
people are doing with LLVM!

Finally, we just wrapped up the third annual LLVM Developer's Meeting,
which was a great opportunity for LLVM people to meet face-to-face and
exchange ideas.  The event web site (http://llvm.org/devmtg/2009-10/)
includes slides and videos for most of the talks.  We send many thanks
out to Apple, Google, Adobe and Qualcomm Incorporated for sponsoring
the event!

This is awesome news, and I'm glad the the ldc people are keeping an eye on D2. I wonder what's the status regarding exceptions on Windows or Windows support in general. I couldn't find information through a summary search through the release notes. My understanding is that currently there is no release at all of ldc. Is that correct? Andrei

Other than possible lack of manpower, I don't see why the LDC people don't just use setjmp/longjmp exception handling in the interim. It seems like a good "better than nothing" solution until LLVM gets fixed properly.

The reason *is* lack of manpower. No one has volunteered to implement sjlj exception handling.

http://dsource.org/projects/ldc). LLVM 2.6 will be the base of the next release. But the LDC devs like to upgrade to the newest DMD "working" frontend first, because of the latest regressions. Hopefully that will be 1.051. Regarding exceptions on windows. The LLVM team has no (intermediate?) plans so far to add exception support for windows. They lack of manpower (iirc, they only have one windows dev). There is some effort to implement it in LDC, but it's tedious work. Nevertheless, thumbs up!

Andrei, I cannot say just how exciting it was to first break this news on D NG. My thinking is along lines: Scala is to JVM as D *is to/should be to/should aspired to be to* LLVM. btw. What's the latest ETA for TDPL? Justin

Amazon mentions March 15, 2010: http://www.amazon.com/exec/obidos/ASIN/0321635361/modecdesi-20

Thanks; just had a look at that link. Did Andrei give a preview of the table of contents somewhere? I'd certainly welcome a chapter (or at least a detailed honorable mention) on LLVM though perhaps that would be outside of the scope of his book.

An overview of LLVM/ldc would be outside of the scope of the book, but I encourage you to write about it and I'll make sure I'll insert a pointer in the book. Andrei

Thank you for your interest. I plan to send a complete draft out on Nov 9. We're less stable with threads than I'd want, so probably the Nov 9 draft will not include the threads chapter. Then we'll pipeline reviews and editing with writing the last chapter and the threading API. We could use all the help we can get with threads and all other aspects of the language. I understand the mighty attraction of a conversation about semicolons, but I would have hoped someone would find the time and motivation to e.g. experiment with the MRU cache for the ~= operator. It looks like in the end it's down to Walter, Don, Sean, and myself for completing everything there is to be completed. Hopefully we'll find ways to cooperate with David Simcha of integrating his concurrency work too. Andrei
