ResizeBilinear on Power8

[Anonymous]

I wanted to compare performance of bilinear resizing with OpenCV, so I wrote this function:

void resize_simdlib(int scale, const cv::Mat &src, cv::Mat &dst)
{
    dst = cv::Mat::zeros(src.rows*scale, src.cols*scale, src.type());
    typedef Simd::View<Simd::Allocator> View;
    View view_src = src;
    View view_dst = dst;
    Simd::ResizeBilinear(view_src, view_dst);
}

It works fine on Windows with MSVC and on x86 Linux with gcc. However, if built with gcc on a RHEL Power8 server (where it uses VMX, I guess?) color channels get messed up, the output image is mostly gray with some diagonal mosaic stripes, sort of what happens if a stride value is wrong. Am I using the resize function correctly?
(I will attach the image, if necessary.)

As I can see you use Simd Library correctly. Especialy if you have correct result at x86. So I suppouse that there is an error in VMX version of function ResizeBilinear. I'm sorry but can't check this fact, and fix the error because I haven't got access to Power PC at the moment.

It seems to work correctly if the system is big endian (my previous attempt was on a little endian system). Probably some of those clever binary tricks need to be different for different ending.

Yes. It is similar to truth. When I was porting the algorithms to PowerPC platform, I was supposing that it was big endian.
