<p><a href="http://dragonegg.llvm.org/">DragonEgg</a> is a
<a href="http://gcc.gnu.org/wiki/plugins">gcc plugin</a> that replaces GCC's
- optimizers and code generators with LLVM's. It works with gcc-4.5 or gcc-4.6,
- targets the x86-32 and x86-64 processor families, and has been successfully
- used on the Darwin, FreeBSD, KFreeBSD, Linux and OpenBSD platforms. It fully
- supports Ada, C, C++ and Fortran. It has partial support for Go, Java, Obj-C
- and Obj-C++.</p>
+ optimizers and code generators with LLVM's. It works with gcc-4.5 and gcc-4.6
+ (and partially with gcc-4.7), can target the x86-32/x86-64 and ARM processor
+ families, and has been successfully used on the Darwin, FreeBSD, KFreeBSD,
+ Linux and OpenBSD platforms. It fully supports Ada, C, C++ and Fortran. It
+ has partial support for Go, Java, Obj-C and Obj-C++.</p>
<p>The 3.1 release has the following notable changes:</p>
<ul>
- <li>...</li>
+ <li>Partial support for gcc-4.7. Ada support is poor, but other languages work
+ fairly well.</li>
+
+ <li>Support for ARM processors. Some essential gcc headers that are needed to
+ build DragonEgg for ARM are not installed by gcc. To work around this,
+ copy the missing headers from the gcc source tree.</li>
+
+ <li>Better optimization for Fortran by exploiting the fact that Fortran scalar
+ arguments have 'restrict' semantics.</li>
+
+ <li>Better optimization for all languages by passing information about type
+ aliasing and type ranges to the LLVM optimizers.</li>
+
+ <li>A regression test-suite was added.</li>
</ul>
