Release 10.20 Changes
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
