Hi all,<br>
<br>
We are planning to remove the -fvia-c way of compiling code<br>
(unregisterised compilers will continue to compile via C only, but<br>
registerised compilers will only use the native code generator).<br>
We'll probably deprecate -fvia-c in the 6.14 branch, and remove it in<br>
6.16.<br>
<br>
Simon Marlow has recently fixed FP performance for modern x86 chips in<br>
the native code generator in the HEAD. That was the last reason we know<br>
of to prefer via-C to the native code generators. But before we start<br>
the removal process, does anyone know of any other problems with the<br>
native code generators that need to be fixed first?<br><br></blockquote><div><br></div><div>What about loop unrolling? I remember seeing some discussion about that quite a while ago. Do we have any feature requests (i.e. performance bugs) related to that?</div>
<div><br></div><div>Cheers,</div><div>Johan</div><div><br></div></div>
