Re: [wwwdocs] gcc-4.0/changes.html - Mention SMS as new optimization.


Hi Mostafa,

thanks for the updated patch (and thanks also to Giovanni for his useful
comments).

If you'd like, and I'd appreciate that, it would be a good idea to have
a web page news/sms.html which describes your changes in a bit more 
detail and make the entry in changes.html shorter and refer to that
page instead.

If you don't want to do that, the current patch is fine as well, with
just a couple of minor changes:

Index: changes.html
===================================================================

<code>-fmodulo-sched</code>

+ 	This is a preliminary implementation of SMS, so we are able to

+ 	are expected in the coming releases of GCC.

For the longer version that I suggested for news/sms.html, it would be
nice to have a brief idea on what sort of loops we are currently able
to handle; or you could add this to the manual and refer from changes.html
to the manual.
