This patch adds the SVE built-in types defined by the Procedure Call Standard for the Arm Architecture: https://developer.arm.com/docs/100986/0000 It handles the types in all relevant places that deal with built-in types. At the moment, some of these places bail out with an error, including: (1) trying to generate LLVM IR for the types (2) trying to generate debug info for the types (3) trying to mangle the types using the Microsoft C++ ABI (4) trying to @encode the types in Objective C (1) and (2) are fixed by follow-on patches but (unlike this patch) they deal mostly with target-specific LLVM details, so seemed like a logically separate change. There is currently no spec for (3) and (4), so reporting an error seems like the correct behaviour for now. The intention is that the types will become sizeless types: http://lists.llvm.org/pipermail/cfe-dev/2019-June/062523.html The main purpose of the sizeless type extension is to diagnose impossible or dangerous uses of the types, such as any that would require sizeof to have a meaningful defined value. Until then, the patch sets the alignments of the types to the values specified in the link above. It also sets the sizes of the types to zero, which is chosen to be consistently wrong and shouldn't affect correctly-written code (i.e. code that would compile even with the sizeless type extension). The patch adds the common subset of functionality needed to test the sizeless type extension on the one hand and to provide SVE intrinsic functions on the other. After this patch, the two pieces of work are essentially independent. The patch is based on one by Graham Hunter: https://reviews.llvm.org/D59245 Differential Revision: https://reviews.llvm.org/D62960 llvm-svn: 368413
