-notrigraph
The-notrigraph option inhibits the processing of trigraphs. In previous versions,
[LINEBREAK]-notrigraph caused the legacy preprocessor to be invoked. Though this ignored
trigraphs, trigraphs were still interpreted by the compiler in the preprocessed source. The -notrigraph
option no longer invokes the legacy preprocessor, and also suppresses trigraphs from being
interpreted.
This option is not recommended. The proper portable solution is to quote the "?" as "\?".
Verbose Compile and Link Information
Use the following options to obtain additional information about:
• The HP compiler actions while compiling or linking your program.
• The subprocesses executed for a given command line, without running the compiler.
• The current compiler and linker version numbers.
• The Execution time.
-dumpversion
-dumpversion
The +dumpversion option displays the simple version number of the compiler, such as A.06.25.
Compare with the -V option, which displays more verbose product version information.
+dryrun
+dryrun
The +dryrun option generates subprocess information for a given command line without running
the subprocesses. It is useful in the development process to obtain command lines of compiler
subprocesses in order to run the commands manually or to use them with other tools.
Example:
The following command line gives the same kind of information as the -v option, but without
running the subprocesses.
aCC +dryrun app.C
+O[no]info
+O[no]info
The +Oinfo option displays informational messages about the optimization process. This option
may be helpful in understanding what optimizations are occurring. You can use the option at levels
0-4. The default is +Onoinfo at levels 0-4.
+wsecurity
+wsecurity[={1|2|3|4}]
The +wsecurity option can take an argument to control how verbosely the security messages
are emitted. The default level is 2.
+time
+time
The +time option generates timing information for compiler subprocesses. For each subprocess,
estimated time is generated in seconds for user processes, system calls, and total processing time.
This option is useful in the development process, for example, when tuning an application’s
compile-time performance.
