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

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.

aCC +inst_directed prog.C

See Chapter 5: “Using HP aC++ Templates” (page 169) for more information.

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

+inst_implicit_include

The +inst_implicit_include option specifies that the compiler use a process

similar to that of the cfront source rule for locating template definition files. For the

cfront based HP C++ compiler, if you are using default instantiation (that is, if you

are not using a map file), you must have a template definition file for each template

declaration file, and these must have the same file name prefix.

This restriction does not apply in HP aC++. Therefore, if your code was written for HP

C++ and you wish to follow this rule when compiling with HP aC++, you need to specify

the +inst_implicit_include option.
