Equivalent of mpif90 --showme for Cray Fortran Wrapper ftn

Question

I am currently compiling code on a HPC system that was set up by Cray. To call Fortran, C, and C++ compilers it is suggested to use ftn, cc, and CC compiler wrappers provided by Cray.

Now, I would like to know which options the ftn wrapper adds to the actual compiler call (in my case to ifort, but it should not matter). From working with MPI wrappers I know the option --showme to get this information:

> mpif90 --showme
pgf90 -I/opt/openmpi/pgi/ib/include -fast -I/opt/openmpi/pgi/ib/lib -L/opt/openmpi/pgi/ib/lib -lmpi_f90 -lmpi_f77 -lmpi -libverbs -lrt -lnsl -lutil -ldl -lm -lrt -lnsl -lutil
## example from another HPC system; MPI wrapper around Portland Fortran Group Compiler

I am locking for an option like --OPTION_TO_GET_APPENDED_FLAGS that provides the same information for the ftn wrapper

> ftn --OPTION_TO_GET_APPENDED_FLAGS
ifort -one_option -O2 -another_option

Because it is Friday afternoon local time all colleagues with knowledge on this topic left already for their weekend (as well as the cluster support team).

Thanks in advance for the answers.

Answer 1

On the Cray system I am using (Cray Linux Environment (CLE), 27th Apr. 2016), the appropriate option is -craype-verbose:

ftp -craype-verbose
> ifort -xCORE-AVX2 -static -D__CRAYXC [...]

It is written on the man page which I just scanned quickly before asking this question:

-craype-verbose
      Print the command which is forwarded to compiler invocation.
