New and Changed Features

The latest linker patch (PHSS_16841) is needed in order to build shared libraries. See these release notes, Chapter 2, Current Linker Required, for details.

Header File Caching is an additional, simplified method of precompiling header files.

A new debugging option, +objdebug, enables faster links and smaller executable file sizes for large applications.

The latest linker patch (PHSS_16841) is needed in order to use +objdebug. See these release notes, "Chapter 2, Current Linker Required," for details.

Additional Options for Standardizing Your Code:

Additional Options for Code Optimization:

A new template option, +inst_directed, to suppress assigner output in object files. Use it instead of the +inst_none option with code that contains explicit instantiations only and does not require automatic (assigner) instantiation.

The #pragma pack directive allows you to specify the maximum alignment of class fields having non-class types. This pragma may be useful when importing code from other architectures where data type alignment may be different from default HP-PA alignment.

A new Japanese language version of the HP aC++ Online Programmer's Guide is located at: /opt/aCC/html/ja_JP.SJIS

+M[d] and +m[d] options to output the header files upon which your source code depends in a format accepted by the make(1) command.

+We option to selectively interpret a warning or future error as an error.

The __HP_aCC predefined macro to identify the HP aC++ compiler.

At this release, the +inline-level option defaults to 1. In the prior versions, A.01.09, A.01.12, A.03.05, A.03.10, the default was 0 and no inlining was done (the same effect as the +d option).

This change was made based on customer feedback regarding object file size and runtime performance.
