Description Reid Spencer 2006-08-19 01:57:19 PDT 
After the analyze functionality was merged into opt, it now seems to register
multiple command line options. The simple command:

opt < /dev/null

will reproduce this output:

<unknown>: CommandLine Error: Argument 'printm' defined more than once!
<unknown>: CommandLine Error: Argument 'profile-loader' defined more than once!
<unknown>: CommandLine Error: Argument 'print' defined more than once!
opt: Standard Input empty!


Its not clear what's going on. Debugging this problem has lead to the errors
being generated in the bowels of the PassNameParser that is used to collect all
the analysis passes. However, its unclear how this could lead to duplicate pass
registrations.

Perhaps someone with a better handle on this code can figure it out.
