<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-backend-x86 Author: Max Winkler (MaxEW707) <details> <summary>Changes</summary> See https://github.com/llvm/llvm-project/pull/75711 for discussion. As a summary from the PR above, `<adxintrin.h>` includes adc intrinsics and adx intrinsics. To support MSVC STL we need to expose the adc intrinsics inside the currently proposed `<intrin0.h>` header. Move the processor agnostic adc intrinsics into a separate file that can be included from `<immintrin.h>` and the currently proposed `<intrin0.h>`. --- Full diff: https://github.com/llvm/llvm-project/pull/75992.diff 4 Files Affected: - (modified) clang/lib/Headers/CMakeLists.txt (+1) - (added) clang/lib/Headers/adcintrin.h (+160) - (modified) clang/lib/Headers/adxintrin.h (+1-126) - (modified) clang/lib/Headers/immintrin.h (+1-2) ``````````diff diff --git a/clang/lib/Headers/CMakeLists.txt b/clang/lib/Headers/CMakeLists.txt index f8fdd402777e48..735e4e4e3be89b 100644 --- a/clang/lib/Headers/CMakeLists.txt +++ b/clang/lib/Headers/CMakeLists.txt @@ -139,6 +139,7 @@ set(webassembly_files set(x86_files # Intrinsics + adcintrin.h adxintrin.h ammintrin.h amxcomplexintrin.h diff --git a/clang/lib/Headers/adcintrin.h b/clang/lib/Headers/adcintrin.h new file mode 100644 index 00000000000000..b43322f22297d7 --- /dev/null +++ b/clang/lib/Headers/adcintrin.h @@ -0,0 +1,160 @@ +/*===---- adxintrin.h - ADX intrinsics -------------------------------------=== + * + * Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions. + * See https://llvm.org/LICENSE.txt for license information. + * SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception + * + *===-----------------------------------------------------------------------=== + */ + +#ifndef __ADCINTRIN_H +#define __ADCINTRIN_H + +#if !defined(__i386__) && !defined(__x86_64__) +#error "This header is only meant to be used on x86 and x64 architecture" +#endif + +/* Define the default attributes for the functions in this file. */ +#define __DEFAULT_FN_ATTRS __attribute__((__always_inline__, __nodebug__)) + +/* Use C++ inline semantics in C++, GNU inline for C mode. */ +#if defined(__cplusplus) +#define __INLINE __inline +#else +#define __INLINE static __inline +#endif + +#if defined(__cplusplus) +extern "C" { +#endif + +/// Adds unsigned 32-bit integers \a __x and \a __y, plus 0 or 1 as indicated +/// by the carry flag \a __cf.
