Bug ID: 40701
Summary: clang-cl requires SVML intrinsics for VS2019
compatibility
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: neum...@imt.uni-luebeck.de
CC: htmldevelo...@gmail.com, llvm-bugs@lists.llvm.org,

with VS 2019 SVML intrinsic "svmlintrin.h" are included by immintrin.h.
As such clang-cl needs to support SVML intrinsics to be compatible with VS2019.
Small Code example:
#include <immintrin.h>
#include <array>
#include <iostream>
int main()
{
using Vector = std::array<double, 4>;
Vector MyData;
Vector SinData;
Vector CosData;
MyData = { 0.0, 1.31, -3.21, 0.51};
*(__m256d*)(SinData.data()) = _mm256_sincos_pd((__m256d*)CosData.data(),
*(__m256d*)(MyData.data()));
for (auto elem : SinData)
{
std::cout << elem << '\t';
}
std::cout << '\n';
for (auto elem : CosData)
{
std::cout << elem << '\t';
}
std::system("pause");
return 0;
}
