Bug ID: 21616
Summary: LowerSwitch pass fail weirdly
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Transformation Utilities

Test case
The LowerSwitch pass failed in some cases.
After some investigation, I found that the pass fails because of the "case
'9':". If I remove this case, everything works fine.
I'm not sure, but I think it comes from the clustering part of the pass. the
caracter '9' and the caracter ':' follow each other in the ascii table, so it
try to cluster it together (but they don't have the same BB successor).
ps: my LLVM version is the 3.5 release (but didn't appear in the 'version'
field).
