Bundled C Compiler

The bundled C Compiler in HP-UX 11i v3 is version A.06.12 on Itanium®-based servers and B.11.11.16 on PA-RISC. In previous releases, it was supplied for kernel installation and tuning only; it is no longer needed for that, and may be obsoleted in the future.

HP recommends that customers doing development in C obtain the separately available HP C/aC++ Developer's Bundle instead of using the bundled C compiler. The bundled C compiler does not support any optimization or other advanced features found in the Developer's Bundle compiler.

Summary of Change

What’s New for Customers Migrating from HP-UX 11i v1 September 2005?

The bundled compiler that ships as part of HP-UX 11i v3 on Itanium®-based servers is different from the bundled compiler which shipped as part of the HP-UX 11i v2. However, the compilers are highly compatible. Diagnostic message format and identifying numbers have changed. More erroneous and suspicious source constructs are diagnosed. Because the numbers have changed, customers who manipulate the severity of diagnostics on the command line with +Ww### or +We###, or suppress them entirely with +W###, need to modify those command lines.

On PA-RISC, the bundled C compiler is unchanged except for routine maintenance.

Impact

Diagnostic numeric identifiers and diagnostic wording have changed.

Compatibility

Itanium®-based Servers:
- Command lines may need to be changed to specify different numbers for +W###, +We### and +Ww### options.
- Filter scripts which search for specific diagnostic patters will need to be changed.
PA-RISC Servers:
- There are no known compatibility issues.

Performance

This compiler does not support optimization. For compiling performance sensitive applications, obtain the HP C/aC++ Developer’s Bundle.

Documentation

The only documentation specifically relating to the bundled C compiler is its manpage: cc_bundled(1).
