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.
Examples:
• The aCC +time app.C command generates the following information:
process: compiler 0.94/u 0.65/s 4.35/r
process: ld 0.37/u 0.76/s 3.02/r
• The aCC -v +time app.C command generates the following information:
/opt/aCC/lbin/ctcom -inst compiletime -diags 523 -D __hppa -D __hpux
-D __unix -D __hp9000s800 -D __STDCPP__ -D __hp9000s700 -D _PA_RISC1_1

The -v option enables verbose mode, sending a step-by-step description of the compilation
process to stderr. This option is especially useful for debugging or for learning the
appropriate commands for processing a C++ file.
Example:
The aCC -v file.C command compiles file.C and gives information about the
process of compiling.
