Chris Lattner ef1bbfc762 Don't break critical edges for single-bb loops, this helps with PR1877, though ... it is only a partial fix. This change is noise for most programs, but speeds up Shootout-C++/matrix by 20%, Ptrdist/ks by 24%, smg2000 by 8%, hexxagon by 9%, bzip2 by 9% (not sure I trust this), ackerman by 13%, etc. OTOH, it slows down Shootout/fib2 by 40% (I'll update PR1877 with this info). llvm-svn: 45354		2007-12-25 19:06:45 +00:00

Instrumentation	Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.	2007-12-17 01:12:55 +00:00
