------- Comment #35 from burnus at gcc dot gnu dot org 2009-07-27 09:18 ------- (In reply to comment #34) > Does ifort vectorize the exact same implemantion of minloc?
I tried to convert the minloc implementation into Fortran loops - and the result is at http://users.physik.fu-berlin.de/~tburnus/tmp/vect-PR31067/maxloc2.f90 $ ifort -O3 -xHost -diag-enable all maxloc2.f90 maxloc2.f90(25): (col. 5) remark: LOOP WAS VECTORIZED. [timing: 0m1.384s] $ gfortran -O3 -ffast-math -march=native -ftree-vectorize -ftree-vectorizer-verbose=5 maxloc2.f90 maxloc2.f90:1: note: vectorized 0 loops in function. [timing: 0m2.212s] In case it helps: I put the ifort assembler output at: http://users.physik.fu-berlin.de/~tburnus/tmp/vect-PR31067/maxloc2.s -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31067
