There are two 64-bit bitmasks maintained in AttributeImpl.h<https://sdocc.itg.ti.com/ui#file:review=11893/version=393846>: - AvailableFunctionAttrs is part of the AttributeListImpl class, and - AvailableAttrs is part of the AttributeSetNode class Both of these assume that the number of available enum attributes is limited to 64. In fact, a static_assert in Attributes.cpp<https://sdocc.itg.ti.com/ui#file:review=11893/version=393848> enforces that the number of enum attr...

...etail of lib/IR is problematic. This type describes all of the attributes on an individual argument, return value, or function, which IPO transforms often want. Today the getFnAttributes, getRetAttributes, and getParamAttributes APIs find the relevant AttributeSetNode* and wrap it in a new, uniqued AttributeListImpl. This requires callers to keep around the index of the extracted attributes so they can look through the wrapper list. If we make AttributeSetNode public, we can simplify a lot of IPO transform code. Naming ====== The naming of today's APIs is confusing. I'll try to explain what the curre...

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
