[LLVMdev] Modifying the support CommandLine Library to support option categories and iteration over registered options

[Daniel Liew]

Hi Tobias,

The work is complete. I did it and my patch was ignored probably due
to my use of Macros. I then recently re did the work without using
macros and submitted a patch a few days ago.

So far this has been ignored as well :( . If you have commit access
I'd love for you to review the patches and then commit them so my work
will be available in LLVM 3.3 (when it's released) so that we (the
KLEE developers) don't have to force our users to patch LLVM for no
good reason.

Anyway here is the link to the post about my latest patches...

I should note that changed my idea for iterating over command line
options. I didn't think that would be a nice way for people to use it.
Instead with my patch clients can call
llvm::cl::getRegisteredOptions(StringMap<Option*>& map) to get a map
that maps strings (e.g. "help") to the Option* . This gives the client
a lot of control over options. I made an example project that
demonstrates my changes to the LLVM CommandLine library. Here's some
of the code.

Cheers,
Dan.
