Closing this. We should really open new PRs for different intrinsics, when we
have code and perf measurements.

Confirmed, the only loop that was optimized was:
for (i = 0; i < VALUES_SIZE; i++)
values[i] = - GFC_INTEGER_4_HUGE;
The agruments to intrinsics really should have restrict on them to get the

Could help if you list specific functions that you expect to get vectorized. As
far as dotprod is concerned - if it's operating on floats, you nee

Seems like libgfortran vectorizes much better now. Compiling with
"-ftree-vectorize -ftree-vectorizer-verbose=5 -msse2" added to CFLAGS (I didn't
try with FCFLAGS) and grepping the output for LOOP VECTORIZED shows

I'll produce a patch at some point..
