PA-RISC Changes in Hardware Compatibility
In this example, the +DAportable compiler option can be used to create
code compatible for PA-RISC 1.1 and 2.0 systems.
PA-RISC Architectures and Their System
Models
The HP 9000 PA-RISC (Precision Architecture Reduced Instruction Set
Computing) Series 700/800 family of workstations and servers has
evolved from three versions of PA-RISC:
PA-RISC 1.0 The original version of PA-RISC first introduced on
Series 800 servers. The following Series are included:
840, 825, 835/SE, 845/SE, 850, 855, 860, 865, 870/x00,
822, 832, 842, 852, 890, 808, 815, 635, 645.
PA-RISC 1.1 The second version of PA-RISC first introduced on
Series 700 workstations. Newer Series 800 systems
also use this version of the architecture. The following
Series are included: 700, 705, 710, 715, 720, 725, 730,
735, 750, 755, B132L, B160L, B132L+, B180L, C100,
C110, J200, J210, J210XC, 742i, 742rt, 743i, 743rt,
745i, 747i, 748i, 8x7, D (except Dx70, Dx80), E, F, G, H,
I, K (except Kx50, Kx60, Kx70), T500, T520.
PA-RISC 2.0 The newest version of PA-RISC. The following Series
are included: C160, C180, C180XP, C200, C240, J280,
J282, J2240, Dx70, Dx80, Kx50, Kx60, Kx70, T600,
V2200.
For More Information
• See your compiler online help or documentation for details on the +DA
option.
• See the file /opt/langtools/lib/sched.models for a complete
list of model numbers and their architectures. Use the command
model to determine the model number of your system.
