PA-RISC Changes in Hardware Compatibility

PA-RISC Changes in Hardware Compatibility

The HP-UX 10.20 release introduced HP 9000 systems based on the PA-RISC 2.0 architecture. Also, beginning with that release, HP compilers by default generate executable code for the PA-RISC architecture of the machine on which you are compiling.

In previous releases, the compilers generated PA-RISC 1.0 code on all HP 9000 Series 800 servers and PA-RISC 1.1 code on Series 700 workstations. HP compilers now by default generate PA-RISC 1.1 code on 1.1 systems and 2.0 code on 2.0 systems.

Using the +DAportable compiler option provides compatibility of code between PA-RISC 1.1 and 2.0 systems. Note that the HP-UX 10.10 release is the last supported release for PA-RISC 1.0 systems, so code generated by the HP-UX 10.20 release of HP compilers is not supported on PA-RISC 1.0 systems.

The +DA1.0 option will be obsolete in a future release. You can achieve better performance on PA-RISC 1.1 and 2.0 systems by not using this option.

PA-RISC 2.0 Compatibility

The instruction set on PA-RISC 2.0 is a superset of the instruction set on PA-RISC 1.1. As a result, code generated for PA-RISC 1.1 systems will run on PA-RISC 2.0 systems. However, code generated for PA-RISC 2.0 systems will not run on PA-RISC 1.1 or 1.0. The linker issues a hardware compatibility warning whenever it links in any PA-RISC 2.0 object files:

/usr/ccs/bin/ld: (Warning) At least one PA 2.0 object file (sum.o) was detected. The linked output may not run on PA 1.x system.

If you try to run a PA-RISC 2.0 program on a 1.1 system, you'll see a message like:

$ a.out

ksh: ./a.out: Executable file incompatible with hardware
