[ARM][SVE] change vector size at runtime (dynamically)

November 1, 2021November 1, 2021 Berenger

Yes it is possible to change the size of the vector of ARM SVE (like A64FX) using the following code: #define PR_SVE_SET_VL 50 #define PR_SVE_GET_VL 51 #include #include int main(int argc, char** argv){ if(getenv(“VECBITS”)){ int svebitstoset=atoi(getenv(“VECBITS”)); std::cout
