Build failure with Sleef in pow

[Nils Deppe]

Hi Klaus!

I hope you’re doing well! I just tried integrating Sleef into our code base with Blaze. Unfortunately the following fails to compile on Ubuntu 21.10, AMD Threadripper 3970X.

#include <blaze/Math.h>
using namespace blaze;
int main() {
  DynamicVector<double> x{4, -1, 3};
  DynamicVector<double> y = pow(1.0 * x, 1.0);
}

Compiler invocation:

clang++ -march=native -Wall -Wextra -std=c++17 -DBLAZE_USE_SLEEF=1 -O3 test.cpp

and Clang version 13.0.0-2.

‌

Do you have any suggestions on how to fix this?

Thanks in advance!

‌

Best wishes,

Nils

Commit 8fbb3e8 fixes the SIMD pow() functions by extending them to two different SIMD types. The fix is immediately available via cloning the Blaze repository and will be officially released in Blaze 3.9.
