HP aC++/HP C A.06.20 Programmer's Guide

The -Aa option instructs the compiler to use Koenig lookup and strict ANSI for scope

rules. This option is equivalent to specifying -Wc,-koenig_lookup,on and

-Wc,-ansi_for_scope,on.

The default is off. Refer to -Ae option for C-mode description. The standard features

enabled by -Aa are incompatible with earlier C and C++ features.

-AA

The -AA option enables the use of the new 2.0 Standard C++ Library, which includes

the new standard conforming (templatized) iostream library. This is the first release

of the 2.0 library. It conforms to the ISO C++ standard. The default is -AA without

-Wc,-ansi_for_scope.

The 2.0 library, a new addition to the HP C++ runtime, is not compatible with the

version 1.2.1 Standard C++ Library previously bundled with HP aC++. HP aC++ will

continue support for standard C++ library 1.2.1 without name or location change.

Customers should not notice any change when -AA is not used. However, the 1.2.1

library is deprecated and will be replaced by the new library eventually.

To use the new 2.0 library, you must consistently use the -AA option to compile and

link all translation units. Mixing object files within an executable is not supported.

The version of the 2.0 Standard C++ library (libstd_v2) included in this release is

incompatible with the previous versions of the same library. Using the -AA option and

the new 2.0 library creates a binary incompatibility with any other applications/libraries

compiled with the -AA option under the previous version of the aC++ product.

To use the new 2.0 library, you must recompile using the -AA option.

Usage:

The standard features enabled by -AA are incompatible with the older Rogue Wave

Standard C++ Library 1.2.1 and Tools.h++ 7.0.6. All modules must be consistent in using

-AA. Mixing modules compiled with -AA with ones that are not is not supported.

The -Wc,-koenig_lookup,on and -Wc,-ansi_for_scope,on options are also

set.

NOTE: This option is not supported in legacy HP C. This option is ignored with

warnings in C-mode.

-Aarm

This option enables the Tru64 UNIX C++ Annotated Reference Manual (ARM) dialect.

This dialect was the default for Tru64 UNIX C++ compilers through compiler version
