The code in abg-ir.cc that calculated the memory size of an array summed, rather than multiplied, the dimensions. It also did duplicate work for each dimension after the first. Existing code in abg-reader.cc asserted that array size information read from XML match freshly calculated values. This patch corrects the calculation, eliminates the duplicate work and updates the XML reader validation to just emit a warning if old bad array size information is found. * include/abg-ir.h (array_type_def::append_subrange): Remove this function. * src/abg-ir.cc (array_type_def::set_element_type): Add a note about safe usage. (array_type_def::append_subrange): Inline this function into its only caller append_subranges and remove it. (array_type_def::append_subranges): Do correct multiplicative calculation of multidimensional array sizes. * src/abg-reader.cc (build_array_type_def): When checking calculated against read array sizes, warn once if value matches old behaviour rather than raising an assertion. Otherwise, before raising an assertion, emit an informative error message. * tests/data/test-annotate/test14-pr18893.so.abi: Correct array sizes. * tests/data/test-annotate/test17-pr19027.so.abi: Ditto. * tests/data/test-annotate/test19-pr19023-libtcmalloc_and_profiler.so.abi: Ditto. * tests/data/test-annotate/test7.so.abi: Ditto. * tests/data/test-diff-dwarf/test10-report.txt: Ditto. * tests/data/test-diff-dwarf/test11-report.txt: Ditto. * tests/data/test-read-write/test25.xml: Ditto.

This is the Application Binary Interface Generic Analysis and Instrumentation Library. It aims at constructing, manipulating, serializing and de-serializing ABI-relevant artifacts. The set of artifacts that we are intersted is made of quantities like types, variable, fonctions and declarations of a given library or program. For a given library or program this set of quantities is called an ABI corpus. This library aims at (among other things) providing a way to compare two ABI Corpora (apparently the plural of corpus is copora, heh, that's cool), provide detailed information about their differences, and help build tools to infer interesting conclusions about these differences. You are welcome to contribute to this project after reading the files CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree. Communicating with the maintainers of this project -- including sending patches to be include to the source code -- happens via email at libabigail@sourceware.org.
