I'm looking for a FORTRAN compiler that optimizes complex loads
and stores (i.e. a pair of 32-bit complex numbers are loaded using a
64-bit load into a floating point register pair) for the i860.
I've tried the Alliant FX2800 compiler, but it does complex
pairs as separate 32-bit load and store instructions. Any pointers?


Thanks,
