Concerning grammar, most issues I found were missing "the"s and incorrect
third person forms of verbs.  I believe this is due to general differences
between English and German on the one hand, and Slavic languages on the

But I'm disgressing... ;-)  The patch is fine with a few changes pointed

As this is a bit longer than just a simple fact, I suggest to make this a
full sentence; something like "A new web constructions pass...improves..."

"the quality of register allocation" or just "register allocation quality"
"by avoid" -> "by avoiding" or just ", avoiding..."

Omit "it" and add a full stop at the end.

"the loop unroller"

"Experimental implementations the second scheduling pass can be
enabled...", and a comma before "respectively".

Full stop.
