Is there a way to tell gfortran to allign all variables and datastructures
(like arrays) at 16-byte boundaries? Not only the static ones but even
if I do an ALLOCATE(A(N,M)) I want the start of the array to be on an
adress whichs last 4 bits are "0000"?
Why am I asking this? On the Cell BE architectures the DMA-transfers from main memory to the LS of the SPU's must be 16-byte aligned. I am writing a library which gets called by Fortran and performs the caclulations on the SPU's. So if I want to get the data into the Local Stores it has to be 16-byte aligned.
