Can you please let us know when to expect the above intrinsic supported? |
|
We have this in queue to do, but it is low priority relative to other Fortran 2008 requests. Do you have a pull request that would add the intrinsic that we could review? (There are pages on the wiki that explain how to contribute to Flang...) |

As of June it appeared this feature was in review, has it been merged in the tree? Has that code been released? (I'm currently using |

See flang-compiler/flang#298 As of this, the build fails for a different reason: ``` F90-S-0439-An internal subprogram cannot be passed as argument - vec_size (.../bezier/src/fortran/curve.f90: 837) 0 inform, 0 warnings, 1 severes, 0 fatal for compute_length ```

Fortran 2008 NORM2 should be in the current Flang. Please let us know if a recent build of Flang doesn't work in the way you expect. |

As in the topic, flang lacks NORM2 intrinsic. NORM2 is an equivalent to sqrt(dot_product(x,x)), assuming the absence of the option dim parameter for norm2.
