* [GlobalISel] Make GlobalISel a non-optional library.Quentin Colombet2017-08-031-4/+0
| | | | | | | | With this change, the GlobalISel library gets always built. In particular, this is not possible to opt GlobalISel out of the build using the LLVM_BUILD_GLOBAL_ISEL variable any more. llvm-svn: 309990

RegisterBank - support typeless operations like G_STORE/G_LOAD, for scalar use GPR bank. 4.

* Rename AttributeSet to AttributeListReid Kleckner2017-03-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This class is a list of AttributeSetNodes corresponding the function prototype of a call or function declaration. This class used to be called ParamAttrListPtr, then AttrListPtr, then AttributeSet. It is typically accessed by parameter and return value index, so "AttributeList" seems like a more intuitive name. Rename AttributeSetImpl to AttributeListImpl to follow suit. It's useful to rename this class so that we can rename AttributeSetNode to AttributeSet later. AttributeSet is the set of attributes that apply to a single function, argument, or return value.

* Remove getArgumentList() in favor of arg_begin(), args(), etcReid Kleckner2017-03-161-1/+1
| | | | | | | | | | | | | | | | | Users often call getArgumentList().size(), which is a linear way to get the number of function arguments. arg_size(), on the other hand, is constant time. In general, the fact that arguments are stored in an iplist is an implementation detail, so I've removed it from the Function interface and moved all other users to the argument container APIs (arg_begin(), arg_end(), args(), arg_size()).

* Recommit: [globalisel] Change LLT constructor string into an LLT-based ↵Daniel Sanders2017-03-071-2/+3
| | | | | | | | | | | | | | | | | | | | object that knows how to generate it. Summary: This will allow future patches to inspect the details of the LLT. The implementation is now split between the Support and CodeGen libraries to allow TableGen to use this class without introducing layering concerns. Thanks to Ahmed Bougacha for finding a reasonable way to avoid the layering issue and providing the version of this patch without that problem. The problem with the previous commit appears to have been that TableGen was including CodeGen/LowLevelType.h instead of Support/LowLevelTypeImpl.h.

* Revert r297177: Change LLT constructor string into an LLT-based object ...Daniel Sanders2017-03-071-3/+2
| | | | | | | | | | More module problems. This time it only showed up in the stage 2 compile of clang-x86_64-linux-selfhost-modules-2 but not the stage 1 compile. Somehow, this change causes the build to need Attributes.gen before it's been generated. llvm-svn: 297188
