Missing/planned tasks

[mesham]

A list of limitations/short term todos:

• Stencil apply extracts each target into separate stencil regions, should keep these unified
• For loops where initialise array members to 0 or 1, of stencil variables then used later on, these initialisations are not stencilised. This is an issue due to NUMA
• Can not have temporaries in stencils currently
• Better way to interface with C and other Fortran modules (e.g. MPI, dl_timer etc) needed, currently is done via intrinsics
• Support derived types
• Parse FIR (fix parsing in dialect)
• Lint and pyright FIR
• Other FIR types
• Move FIR into dialects/experimental of xDSL
• Pass allocatable arrays to procedures with their bounds intact
• Support array bounds not starting at 1
• Support range operator i.e. a(:,:,:)=.... (both in FIR and also stencil application)
• Support integer to float conversion in arith dialect, that's currently not supported
• Support more unary operators and nary operators
• Reduce number of bridged regions (multiple stencils in a region), for instance "merge" these into one bridged region if there isn't any Fortran code in between them
