HP C/aC++ for PA-RISC Software manual 200

Table 12 New Command-Line Options (continued)

Option	Description
Precompiled	Reduces compilation time and executable file size by precompiling common include (header)
Header File	files.
Options
Template Options	There are new options and new functionality for template processing.
	For more information about HP aC++ templates, see Chapter 5: “Using HP aC++ Templates”
	(page 132).

Obsolete Command-Line Options

Table 13 describes obsolete command-line options for HP aC++.

Table 13 Obsolete Command-Line Options

Option	Description
Debugging Option
-y	In HP C++ (cfront), the -yoption 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++.
Exception Handling Option
+eh	Enables exception handling in HP C++.
	In HP aC++, exception handling is enabled by default. To disable exception handling off, compile
	with the +noeh option.
Library Option
-depth	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
	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++, -depthfunctionality is the default option.
Preprocessor Options
-Ac	Requests the compatibility mode HP C++ preprocessor, cpp. This option is not available in HP
	aC++.
-C	Prevents the preprocessor from stripping comments from your source file. In HP aC++ comments
	are retained.
-Wp	The -Woption no longer accepts p as a subprocess parameter. In HP aC++, there is no separate
	subprocess for the preprocessor.
	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
-pta	Instantiates all members of used template classes and all needed template functions.
-ptb	Invokes ld instead of nm to do simulated linking.
-pth	Uses short file names for template instantiation files.
-ptH"list"	Specifies file name extensions for template declaration files (header files).
-ptn	Instantiates at link time rather than at compile time.
-ptrpath	Specifies an alternate location for the template repository.
