TNS/E pTAL Compiler

H-series systems provide a pTAL compiler that is nearly identical to the pTAL compiler

on G-series systems, except that it produces object files consisting of Itanium

instructions instead of RISC instructions. It has a new command name: EPTAL. The

command line syntax is similar.

The TNS/E pTAL compiler can be run in the Guardian environment and on the PC

either at the Windows command prompt or as part of NSDEE or ETK (TDS is only

supported on G-series RVUs.). NSDEE and ETK enable you to compile and link

programs on a PC. You can compile programs targeted for the TNS/R or TNS/E

system, then copy the object files to a NonStop server and execute them in the

Guardian environment.

Migrating a TNS/R pTAL program to TNS/E pTAL, in most cases, requires no source

code changes. Some programs might require minor source code changes as described

in Section 7, pTAL Migration Tasks.

TNS/E Native C Compiler

The H-series native C compiler is nearly identical to the G-series native C compiler,

except that it produces object files consisting of Itanium instructions instead of RISC

instructions.

Like the TNS/R native C compiler, the TNS/E native C compiler accepts C language

source files that comply with either the ISO/ANSI C Standard or Common Use C

(sometimes called Kernighan and Ritchie C or K&R C). The TNS/E native C compiler

also accepts HP language extensions.

The TNS/E native C compiler can be run in the Guardian and OSS environments and

on the PC either at the Windows command prompt or as part of NSDEE or ETK (TDS

is only supported on G-series RVUs.). The CCOMP command runs the compiler in the

Guardian environment. The TNS/E native C compiler command line syntax is similar to

that of the TNS and TNS/R C compilers. The syntax of the TNS/E c89 and c99

utilities, which run the TNS/E native C compiler in the OSS environment, is similar to

that of the TNS and TNS/R c89 utility.

NSDEE and ETK allow you to run Windows-based cross compilers that enable you to

compile and link programs on a PC under the Windows operating system for execution

on the NonStop server. You can compile programs targeted for either the TNS/R or

TNS/E system, copy the object files to the appropriate NonStop server, and execute

them in the Guardian and OSS environments.

Most TNS/R native C programs can be compiled and run on an H-series system with

no source changes. Some programs might require minor changes as described in

Section 5, Native C and C++ Migration Tasks.
