<li>GCC now diagnoses inline assembly that clobbers register r2.
This has always been invalid code, and is no longer quietly
tolerated.</li>
+ <li>The PowerPC port's support for ISA 3.0 (<code>-mcpu=power9</code>)
+ has been enchanced to include native code generation and new built-in
+ functions.</li>
+ <li>The configuration option <code>--enable=gnu-indirect-function</code>
+ is now enabled by default on PowerPC Linux builds.</li>
+ <li>The PowerPC port will now allow 64-bit and 32-bit integer types to be
+ allocated to the VSX vector registers (ISA 2.06 and above). In addition,
+ on ISA 3.0, 16-bit and 8-bit integer types can go in the vector registers.
+ Previously, only 64-bit integer types were allowed in the traditional
+ floating point registers.</li>
</ul>
