wrong results. You must build all
modules with <code>-mpreferred-stack-boundary=3</code>, including any
libraries. This includes the system libraries and startup modules.</li>
+ <li>Support for the new Intel processor codename Broadwell with RDSEED,
+ ADCX, ADOX, PREFETCHW is available through <code>-madx</code>,
+ <code>-mprfchw</code>, <code>-mrdseed</code>.

+ <li> Support for Intel RTM and HLE intrinsics, built-in
functions and code generation is available via <code>-mrtm</code> and
<code>-mhle</code>.

+ <li> Support for Intel FXSR, XSAVE and XSAVEOPT instruction
sets. Intrinsics and built-in functions are available

</li>
+ <li> x86 backend was improved to allow option
<code>-fscedule-insns</code> to work reliably.
+ This option can be used to schedule instructions better and can
lead to improved performace in certain cases.
+ </li>
<li> Windows MinGW-w64 targets (<code>*-w64-mingw*</code>)
require at least r5437 from the Mingw-w64 trunk. </li>
</ul>
