I've got an example where I think that there should be some loop-invariant optimization happening, but it's not. Here's the C code: #define DIM 8 #define UNROLL_DIM DIM typedef double InArray[DIM][DIM]; __declspec(noalias) void f1( InArray c, const InArray a, const InArray b ) { #pragma clang loop unroll_count(UNROLL_DIM) for( int i=0;i<DIM;i++) #pragma clang loop unroll_count(UNROLL_DIM) for( int j=0;j<DIM;j++) #pragma clang loop unroll_count(UNROLL_DIM)...

I was looking at the code generated from the following c code and noticed extra loads in the inner-loop of these nested for-loops: #define DIM 8 #define UNROLL_DIM DIM typedef double InArray[DIM][DIM]; void f1( InArray c, InArray a, InArray b ) { #pragma clang loop unroll_count(UNROLL_DIM) for( int i=0;i<DIM;i++) #pragma clang loop unroll_count(UNROLL_DIM) for( int j=0;j<DIM;j++) #pragma clang loop unroll_count(UNROLL_DIM) for( int k=0;k<DIM;k++) {...

Obviously I would need to store the summary results inarrays. But I was wondering if that makes sense and how an expert would solve this? I don't want to create an array for each column if possible. Thanks for the kind support, Bernd [[alternative HTML version deleted]]
