Thanks. One comment: I think you will increase the binary size by inlining the
reduction. Could you consider keeping the current libgfortran version and
protecting the scalarization by
if (!optimize_size)
Or, if you replace unconditionally the library version, can you list the
library funcition at http://gcc.gnu.org/wiki/LibgfortranAbiCleanup to make sure
that it gets removed when gfortran breaks the ABI. (The latter has to happen
when we change the array descriptor.)
