Debugging Optimized Code (DOC)

In conjunction with the HP Distributed Debugging Environment (DDE), the HP Pascal/HP-UX compiler now provides support for debugging optimized code. This support includes:

Tracebacks with line-number annotation.
Setting breakpoints and single-stepping at the source statement level.
Mapping between source statements and machine instructions.
Viewing and modifying global variables at procedure call boundaries.
Viewing and modifying parameters on procedure entry.

To enable debugging of optimized code, specify the -g command-line option together with the -O, +O1, or +O2 option. Currently, debugging is supported at optimization levels 2 and below. If you use -g with the +O3 or +O4 option, the compiler issues a warning stating that the options are incompatible, and ignores the -g option.
