Benjamin Kramer	8d6a8c130b	SimplifyCFG: Track the number of used icmps when turning a icmp chain into a switch. If we used only one icmp, don't turn it into a switch. ...

Benjamin Kramer	62aa46b852	SimplifyCFG: Also transform switches that represent a range comparison but are not sorted into sub+icmp. ... This transforms another 1000 switches in gcc.c. llvm-svn: 124826	2011-02-03 22:51:41 +00:00
