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 :

*<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>*
