Description Alexey Proskuryakov 2006-03-29 08:27:32 PST
Bison currently reports 37+4 shift/reduce and reduce/reduce conflicts, this patch gets the number down to 7+0.

I have fixed the reduce/reduce conflicts, then noticed that two of the fixes were already made in KDE tree (the other two are different because declaration blocks are described in quite different ways). Shift/reduce fixes are just merged from KDE, r332845 by Michael Matz.

It's a little strange to give a space and a selector the same precedence as the "unimportant" token. I see that it might work, but it seems a bit obscure or subtle.

But that's a nitpick. This change looks great! r=me

(In reply to comment #2)

The precedence changes are only needed for shift/reduce fixes, taken from KDE. I cannot say that I understood them particularly well.

Landed, r13560.
