Change the enhanced instruction set (File Properties -> C/C++ -> Code Generation -> Enable Enhanced Instruction Set) for the following files:
- FastNoiseSIMD_sse2.cpp:
/arch:SSE2
- FastNoiseSIMD_sse41.cpp:
/arch:SSE2
- FastNoiseSIMD_avx2.cpp:
/arch:AVX2
or/arch:AVX
- FastNoiseSIMD_avx512.cpp:
/arch:AVX2
or/arch:AVX
For the above files disable whole program optimization (File Properties -> C/C++ -> Optimization -> Whole Program Optimization) since this can lead to the compiler inlining unsupported intrinsics into unmanaged locations.
Use compiler setting -std=c++11
, and the following for individual files:
- FastNoiseSIMD_sse2.cpp:
-msse2
- FastNoiseSIMD_sse41.cpp:
-msse4.1
- FastNoiseSIMD_avx2.cpp:
-mavx2
- FastNoiseSIMD_avx512.cpp:
-mavx512f
- Visual Studio 2010+
- G++/GCC 4.7+
- Clang/LLVM 3.1+
If AVX2 in unsupported on your compiler, disable AVX2 compilation by commenting out "#define FN_COMPILE_AVX2" in FastNoiseSIMD.h
