New and Changed Features

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.
