Since the work on un-sharing diff tree nodes, it looks like some
reports of regression tests on i686 order functions and variables in
different orders, leading to test failures on 32 bits platforms
because they are different fromthe 64 bits platforms that we use as a
reference. This patch sorts (lexicographically) the children diff
nodes of a given diff node in general, and also sorts the set of diff
nodes for functions and variables that have sub-type changes, in a
given corpus_diff. That way, the result of the diff report should be
sorted the same way, whatever the platform.
* include/abg-comparison.h (function_decl_diff_sptrs_type)
(var_diff_sptrs_type): New typedefs.
(corpus_diff::{changed_functions, changed_variables}): Declare new
methods.
* src/abg-comparison.cc (sort_string_function_decl_diff_sptr_map)
(sort_string_var_diff_sptr_map): Forward declare these static
functions there were already defined later.
(struct diff_less_than_functor): Define new comparison functor.
(diff::append_child_node): Sort the children diff nodes of a given
diff node.
(corpus_diff::priv::changed_fns_map_): Renamed the data member
corpus_diff::priv::changed_fns_ into this.
(corpus_diff::priv::changed_fns_): New data member that is a
sorted vector of changed functions.
(corpus_diff::priv::{lookup_tables_empty, clear_lookup_tables}):
Adjust changed_fns_ -> changed_fns_map_ and changed_vars_ ->
changed_vars_map_.
(corpus_diff::priv::ensure_lookup_tables_populated): Likewise.
Sort the changed functions and changed variables.
(corpus_diff::priv::apply_filters_and_compute_diff_stats): Adjust
changed_fns_ -> changed_fns_map_ and changed_vars_ ->
changed_vars_map_. Also, walk the changed functions and variables
diff nodes in their sorted order.
(corpus_diff::priv::{categorize_redundant_changed_sub_nodes,
clear_redundancy_categorization, maybe_dump_diff_tree}): Walk the
changed functions and variables diff nodes in their sorted order.
* include/abg-ir.h
(function_decl::get_pretty_representation_of_declarator):
Declarenew method.
* src/abg-ir.cc
(function_decl::get_pretty_representation_of_declarator): Define
new function. Its content got split out of ...
(function_decl::get_pretty_representation): ... this one.
* src/abg-comparison.cc (corpus_diff::chain_into_hierarchy):
Consider the sorted the children nodes of a diff tree node.
(corpus_diff::append_child_node): Keep the children nodes of a
diff tree node sorted.
(corpus_diff::{changed_functions, changed_variables, length,
report}): Adjust.
(corpus_diff::{changed_functions_sorted,
changed_variables_sorted}): Define new functions.
(function_comp::operator()): First compare the qualified function
names along with the parameter declarations, then the rest.
(sort_string_function_decl_diff_sptr_map)
(sort_string_var_diff_sptr_map): Adjust.
* tests/data/test-abicompat/test0-fn-changed-report-0.txt: Adjust.
* tests/data/test-diff-suppr/test5-fn-suppr-report-0.txt: Adjust.
* tests/data/test-diff-suppr/test8-redundant-fn-report-0.txt:
Adjust.
