Make I/O actions known to the declarative debugger. The debugger doesn't do
anything with them yet beyond asking about their correctness.
browser/io_action.m:
New module for representing I/O actions, and for constructing the map
from I/O action numbers to the actions themselves.
browser/mdb.m:
Include the new module.
browser/declarative_analysis.m:
Make the map from I/O action numbers to the actions themselves part
of the analyzer state, since conversions from annotated trace nodes
to EDT nodes may now require this information. This information is
stored in the analyzer state because only the analyser needs this
information (when converting annotated trace nodes to EDT tree nodes).
It is not stored in the trace node store because its lifetime is
different: its contents does not change during a tree deepening
operation.
browser/declarative_execution.m:
Store the current value of the I/O action counter with each call and
exit node. The list of I/O actions associated with the atom of the exit
node is given by the I/O actions whose counters lie between these two
values (initial inclusive, final exclusive).
browser/declarative_debugger.m:
browser/declarative_oracle.m:
Distinguish atoms associated with exit nodes from atoms associated with
call nodes, since the former, but not the latter, now have a list of
I/O actions associated with them.
browser/declarative_user.m:
Add mechanisms for printing and browsing the I/O actions associated
with EDT nodes and bugs.
runtime/mercury_trace_base.[ch]:
Move the code for finding an I/O action here from the file
mercury_trace_declarative.c, for use by browser/io_action.m.
runtime/mercury_layout_util.[ch]:
Move a utility function here from mercury_trace_declarative.c,
for use by the code moved to mercury_trace_base.c.
trace/mercury_trace_declarative.c:
When invoking the front end, pass to it the boundaries of the required
I/O action map. Cache these boundaries, so we can tell the front end
when reinvocation of the back end by the front end (to materialize
previously virtual parts of the annotated trace) does not require
the reconstruction of the I/O action map.
trace/mercury_trace_vars.[ch]:
Separate out the code for finding an I/O action from the code for
browsing it, for use in mercury_trace_declarative.c.
Note places where the implementation does not live up to the
documentation.
trace/mercury_trace.[ch]:
Add a parameter to MR_trace_retry that allows retries to cross I/O
actions without asking the user if this is OK.
trace/mercury_trace_internal.c:
trace/mercury_trace_external.c:
Pass MR_FALSE as this new parameter to MR_trace_retry.
tests/debugger/declarative/tabled_read_decl.{m,inp,exp}:
A slightly modified copy of the tests/debugger/tabled_read_decl test
case, to check the declarative debugger's handling of goals with I/O
actions.
tests/debugger/declarative/Mmakefile:
Enable the new test case.
