Well, its been quite some time... hope your are all as well as you have been
more than a year ago.
It just happend to be that i wrote a small pass (albeit for 2.5) which
removes the select instructions which had not been there in 2.2 8-/.
Since they made my bitrotting backend sad i had to find a way to get rid of
The attached pass is slighly inspired (concerning the skeleton) by the lower
switch pass. It simply replaces the select instruction with a branch to to
dummy blocks which in turn unconditionally branch back to "tail" block which
contains the remaining instructions (guarded of course by a phi node).
Attached is also my small testdirectory (which is sadly not a real test).
It would nice if this pass would find its way to mainline.
I would also like this place to thank Tilmann, Nicholas and Daniel for their
great support via IRC.
