--- Comment #6 from Mike Hommey <mh+gcc at glandium dot org> --- Replacing __attribute__((always_inline)) with inline on the two blend_pixels functions makes it go down to 30s with GCC 10. See https://bugzilla.mozilla.org/show_bug.cgi?id=1700520#c9 why the functions were marked always_inline in the first place.
