llvm dev - Oct 2010 - [LLVMdev] 2.8 Release notes

Hi All,

I've finished the first draft of the 2.8 release notes:
http://llvm.org/docs/ReleaseNotes.html

Please feel free to commit improvements and enhancements.  There are "a
lot" of changes that went into 2.8, but I think I've scraped most of
them out of the commits.  However, it is also highly likely that I missed
something, so if I missed your favorite feature, please speak up or fix it.

If you are aware of important API changes, please commit improvements to the
"Major Changes and Removed Features" section, or send in patches for
changes.  Thanks!

-Chris

Hi All,

I just noticed a small typo for "Altivec" in

>>>     o Added support for SSE, ARM NEON, and Altvec <<<
Best regards,

LLVM 2.8 added a fifth isVolatile field for memset
introduced with LLVM r100304.
http://llvm.org/viewvc/llvm-project?view=rev&revision=100304

This caused a runtime failure for JIT projects using memcpy, memmove,
and memset.
For what I know this are the only API change that I had to be aware of
when updating Icedtea to support LLVM 2.8.

Hi

The platformindependent OpenJDK/IcedTea Shark JIT have been updated to
support LLVM 2.8.
Here are the icedtea externalproj doc_section for inclusion in the
release notes :

-Xerxes

*<!--=========================================================================-->*
*<div class=**"doc_subsection"**>*
*<a name=**"icedtea"**>IcedTea *Java Virtual Machine
Implementation*</a>*
*</div>*

*<div class=**"doc_text"**>*
*<p>*
*<a
href=**"http://icedtea.classpath.org/wiki/Main_Page"**>*IcedTea*</a>*
provides a
harness to build OpenJDK using only free software build tools and to provide
replacements for the not-yet free parts of OpenJDK.  One of the extensions that
IcedTea provides is a new JIT compiler named *<a
href=**"http://icedtea.classpath.org/wiki/ZeroSharkFaq"**>*Shark*</a>*
which uses LLVM
to provide native code generation without introducing processor-dependent
code.
*</p>

<p**> OpenJDK* 7 b112, Icedtea6 1.9 and Icedtea7 1.13 and later have been
tested
and are known to work with LLVM 2.8
(and continue to work with older LLVM releases >= 2.6 as well).*</p>*

*</div>*

This missed the cutoff date for the release notes (Saturday), sorry!

Hi Chris,

just spotted that the libc++ link in the 2.8 release notes is invalid, points to
http://libc++.llvm.org/, should be ...libcxx...

Fixed in https://llvm.org/svn/llvm-project/llvm/trunk at 115837

Thanks for spotting this.
