Summary: This patch implements the following ACLE intrinsics: uint32_t __arm_vcx1_u32(int coproc, uint32_t imm); uint32_t __arm_vcx1a_u32(int coproc, uint32_t acc, uint32_t imm); uint32_t __arm_vcx2_u32(int coproc, uint32_t n, uint32_t imm); uint32_t __arm_vcx2a_u32(int coproc, uint32_t acc, uint32_t n, uint32_t imm); uint32_t __arm_vcx3_u32(int coproc, uint32_t n, uint32_t m, uint32_t imm); uint32_t __arm_vcx3a_u32(int coproc, uint32_t acc, uint32_t n, uint32_t m, uint32_t imm); uint64_t __arm_vcx1d_u64(int coproc, uint32_t imm); uint64_t __arm_vcx1da_u64(int coproc, uint64_t acc, uint32_t imm); uint64_t __arm_vcx2d_u64(int coproc, uint64_t m, uint32_t imm); uint64_t __arm_vcx2da_u64(int coproc, uint64_t acc, uint64_t m, uint32_t imm); uint64_t __arm_vcx3d_u64(int coproc, uint64_t n, uint64_t m, uint32_t imm); uint64_t __arm_vcx3da_u64(int coproc, uint64_t acc, uint64_t n, uint64_t m, uint32_t imm); Since the semantics of CDE instructions is opaque to the compiler, the ACLE intrinsics require dedicated LLVM IR intrinsics. The 64-bit and 32-bit variants share the same IR intrinsic.

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
