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

NOTE: This option is supported in C++ only and ignored in C-mode.
Trigraph Processing Suppression Option
The -notrigraphoption suppresses trigraph processing.
-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.06.20.
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.
