18166 - Abidiff fails with internal on Libtirpc ABI in XML format It turns out the support for reading the native libabigail XML format is falling short since the work on (late) type canonicalizing. The type ID -> XML node map is wrongly considered as being per corpus data while it should be per translation unit data; type IDs are unique only for a given translation unit. The code to walk a XML sub-tree to perform the ID -> node mapping is wrongly walking all the XML node after the sub-tree node too; that is, it walks the entire corpus file starting from the XML sub-tree node it's given. It should only walk the sub-tree it's given. These two issues normally solve the crash reported here. But then there are other related issues too. The native XML format reader doesn't populate the set of exported declarations for the current corpus it's building. This patch addresses all these issues and makes tests/test-abidiff.cc supports corpus files for a new regression test. * src/abg-reader.cc (read_context::m_exported_decls_builder_): New data member. (read_context::read_context): Initialize it. (read_context::{type_is_from_translation_unit, get_exported_decls_builder, set_exported_decls_builder, maybe_add_fn_to_exported_decls, maybe_add_fn_to_exported_decls, type_id_new_in_translation_unit}): New member functions. (read_context::clear_per_translation_unit_data): Clear id->xml node map here ... (read_context::clear_per_corpus_data): ... not here. (read_context::walk_xml_node_to_map_type_ids): Only walk the sub-tree we are asked to walk. (read_translation_unit_from_input): Cleanup. (read_corpus_from_input): Wire populating of exported declarations of the current corpus. (build_function_decl, build_var_decl): Populate exported declarations of the current corpus here. (build_type_decl, build_qualified_type_decl) (build_pointer_type_def, build_reference_type_def) (build_array_type_def, build_enum_type_decl, build_type_decl) (build_template_tparameter): Adjust assert on ID to make sure it's the first type it's being defined in the current translation unit. * tests/data/test-abidiff/test-corpus0-report0.txt: New test reference output. * tests/data/test-abidiff/test-corpus0-v{0,1}.so.abi: New test input. * tests/test-abidiff.cc (specs): Add the test inputs above to the list of inputs over which to run the test harness. (main): Support reading corpora too, as this test harness was reading just translation units before. (tests/data/Makefile.am): Add test material above to source distribution.
