Release 10.20 Changes

The Release 10.20 changes are described here:

New +DA designations for PA-RISC 2.0 model and processor numbers to generate code for the PA-RISC 2.0 systems. Also a +DAportable option to generate code compatible across PA-RISC 1.1 and 2.0 workstations and servers. Default architecture object code generation is now determined automatically for all systems as that of the machine on which you compile.
New +DS designations for PA-RISC 2.0 model and processor numbers to perform instruction scheduling tuned for PA-RISC 2.0 systems. Default instruction scheduling is now determined automatically for all systems as that of the machine on which you compile.
New or changed optimization options to enhance performance:
- +Odataprefetch -- to generate data prefetch instructions for data structures referenced within innermost loops.
- +Oentrysched -- changing to make save and restore operations more efficient.
- +Ofltacc -- to provide better performance for PA-RISC 2.0 targets.
- +Oloop_unroll -- to enable loop unrolling.
- New +help option for ld -- to invoke online help for the HP linker and libraries.
