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.
