There are new options and new functionality for template processing.Template Options

Obsolete Command-Line Options
Table 13 describes obsolete command-line options for HP aC++.
Table 13 Obsolete Command-Line Options
DescriptionOption
Debugging Option
In HP C++ (cfront), the -y option generates a Static Analysis database if SoftBench is installed and
/opt/softbench/bin is at the beginning of your path. The option is not required in HP aC++.
-y
Exception Handling Option
Enables exception handling in HP C++.+eh
In HP aC++, exception handling is enabled by default. To disable exception handling off, compile
with the +noeh option.
Library Option
In HP C++, this option instructs runtime system to traverse the shared library list in a depth-first
manner when calling static constructors and when loading the libraries. The default is to traverse
-depth
the shared libraries in a left-to-right order when calling static constructors. The order of execution
of static constructors within each shared library is not affected by this option.
In HP aC++, -depth functionality is the default option.
Preprocessor Options
Requests the compatibility mode HP C++ preprocessor, cpp. This option is not available in HP
aC++.
-Ac
Prevents the preprocessor from stripping comments from your source file. In HP aC++ comments
are retained.
-C
The -W option no longer accepts p as a subprocess parameter. In HP aC++, there is no separate
subprocess for the preprocessor.
-Wp
Use the CC command (HP C++) as a workaround:
Example:
CC prog.C -I /opt/aCC/include -I /opt/aCC/include/iostream -I /usr -I /usr/include
See “Migration Considerations Related to Preprocessing” (page 208) for more information.
Template Options
Instantiates all members of used template classes and all needed template functions.-pta
Invokes ld instead of nm to do simulated linking.-ptb
Uses short file names for template instantiation files.-pth
Specifies file name extensions for template declaration files (header files).-ptH"list"
Instantiates at link time rather than at compile time.-ptn
Specifies an alternate location for the template repository.-ptrpath
