Hi.
Sorry for bringing this again.
I really need to find source of this bug.  Can somebody give address/name of
person who knows ARM implementation in LLVM in more details and to whom I could
address my questions directly?

Hi, Anton.
I have tried with sources taken from trunk one or two weeks ago - they have same
behavior.
I will now try again with latest sources.
