Cool I renamed it, per Sean's suggestion, to HowToUseAttributes. Committed as r174961 The doc should be live now: http://llvm.org/docs/HowToUseAttributes.html Cheers, Joe Abbey On Feb 12, 2013, at 3:26 AM, Bill Wendling <wendling at apple.com<mailto:wendling at apple.com>> wrote: Hi Sean, I think it can go in as it is.

I would like to add a target-dependent attribute to the LLVM IR, and the guidance in http://llvm.org/docs/HowToUseAttributes.html says that target-dependent attributes should not occupy a slot in the Attribute::AttrKind enum, but I have yet to find an attribute that is represented in the IR that does not also have a slot in the AttrKind enum. We are limited to 63 slots in the AttrKind enum because it is represented in...

The attached patch creates a skeleton to expand Attributes documentation in the future. It is currently only linked to the index. Ok to commit?

This looks like a good starting point. I would prefer to call it HowToUseAttributes.rst though (it is essentially a HowTo).

...e the parameter index of attributes is via the addAttribute methods of the Function class or the AttributeSet. This is quite inefficient as a new AttributeSet is constructed every time. In fact, it takes the bulk of the time my codegen consumes when dealing with large parameter sets. "HowToUseAttributes" suggests that AttrBuilder can be used as a mutable helper for this purpose. However, it seems to me that this can build the set of attributes that describe a single parameter, rather than a full set with indices. I'm essentially looking for something like: static AttributeSet get...
