Allow uses to associate with each breakpoint in mdb a list of print actions
that should be executed automatically when execution arrives at the breakpoint.
A new print list (a list of things to be printed) can be attached to an
existing breakpoint via the new "break_print" command, or it can be attached
to a breakpoint being created via the existing "break" command.
NEWS:
Mention the new capability.
doc/user_guide.texi:
Document the new capability.
trace/mercury_trace_spy.[ch]:
Keep a print list with every breakpoint, and add functions to
manipulate print lists.
Convert this module to four space indentation to keep indent levels
manageable.
trace/mercury_trace.c:
Conform to the updated interface of the mercury_trace_spy module.
trace/mercury_trace_internal.[ch]:
When the internal debugger is invoked at an event, whether
interactively or not, take an extra parameter specifying the
print list, if any, to be executed.
Implement the new "break_print" command and the new options of
the "break" command.
Conform to the updated interface of the mercury_trace_spy module.
trace/mercury_trace_declarative.c:
Conform to the updated interface of the mercury_trace_internal module.
tests/debugger/breakpoints.{inp,exp*}:
Test the new capability.
tests/debugger/completion.exp:
tests/debugger/mdb_command_test.inp:
Update to reflect the new command.
