HP aC++/HP C A.06.25 Programmer's Guide

NOTE: This option is deprecated as of version A.06.05 and if used, it issues a warning

that -Bprotected_defis almost always what should be used in its place.

Template Options

By using a template option on the aCC command line, you can:

• Close a library or set of link units, to satisfy all unsatisfied instantiations without

creating duplicate instantiations.

• Specify what templates to instantiate for a given translation unit.

• Name and use template files in the same way as for the cfront based HP C++

compiler.

• Request verbose information about template processing.

NOTE: All template options on an aCC command line apply to every file on the

command line. If you specify more than one incompatible option on a command line,

only the last option takes effect.

+[no]dep_name

The +[no]dep_name option enforces strict dependent-name lookup rules in templates.

The default is +dep_name.

+inst_compiletime

The +inst_compiletime option causes the compiler to use the compile time (CTTI)

instantiation mechanism to instantiate templates. This occurs for every template used

or explicitly instantiated in this translation unit and for which a definition exists in the

translation unit. This is the default.

NOTE: This option is supported in C++ only and ignored in C-mode.

+inst_directed

The +inst_directed option indicates to the compiler that no templates are to be

instantiated (except explicit instantiations). If you are using only explicit instantiation,

specify +inst_directed. The following example compiles file.C with the resulting

object file containing no template instantiations, except for any explicit instantiations

coded in your source file.
