+IA-64 processor (also known as IPF, or Itanium Processor Family)
+running GNU/Linux.
+
+The toolchain is not completely finished, so requirements will continue
+to change.
+GCC 3.0.1 and later require glibc 2.2.4.
+GCC 3.0.2 requires binutils from 2001-09-05 or later.
+GCC 3.0.1 requires binutils 2.11.1 or later.
+
+None of the following versions of GCC has an ABI that is compatible
+with any of the other versions in this list, with the exception that
+Red Hat 2.96 and Trillian 000171 are compatible with each other:
+3.0.2, 3.0.1, 3.0, Red Hat 2.96, and Trillian 000717.
+This primarily affects C++ programs and programs that create shared libraries.
+Because of these ABI incompatibilities, GCC 3.0.2 is not recommended for
+user programs on GNU/Linux systems built using earlier compiler releases.
+GCC 3.0.2 is recommended for compiling linux, the kernel.
+GCC 3.0.2 is believed to be fully ABI compliant, and hence no more major
+ABI changes are expected.

 LynxOS 2.2 and earlier comes with GCC 1.x already installed as
 @file{/bin/gcc}.  You should compile with this instead of @file{/bin/cc}.
