--- Comment #2 from Witold Baryluk <witold.baryluk+gcc at gmail dot com> --- Added a minimized test case that has only one outer loop, and f and h are removed for simple inlined replacement. Example diagnostic: $ gcc -std=c17 -march=knm -O3 -ffast-math -fassociative-math -ftree-vectorizer-verbose=2 -fopt-info-vec-all -ggdb -Wall mesh_minimal.c -o mesh_minimal_knm -lm mesh_minimal.c:34:3: missed: couldn't vectorize loop mesh_minimal.c:34:3: missed: not vectorized: latch block not empty. mesh_minimal.c:33:13: note: vectorized 0 loops in function.
