Commit4252dfd6added code to allow the ABI write/reread and compare phases of the tests to be skipped in the case that no ABI files are given for comparison. Unfortunately, the new code skipped those phases unconditionally. This patch changes the in_abi_path and out_abi_path values used in in_out_specs used to trigger the early termination from "" to NULL and updates the conditional logic checking them. Several subsequent commits which affect ABI output were missing these changes to the test data files. This change fixes the following list of commits.4252dfd6dwarf-reader: handle symtab.section_header.sh_entsize == 04457c10edwarf-reader: handle binaries with missing symtab34e867e7dwarf-reader: remove superfluous ABG_ASSERT2d5389f2Fix size calculations for multidimensional arrays.246ca200corpus/writer: sort emitted translation units by path namee8bf5b80Bug 25989 - type_topo_comp doesn't meet irreflexive requirements Finally, this commit also corrects some bad code formatting. * tests/test-read-dwarf.cc (in_out_specs): Use NULL instead of empty ABI paths for test25, test26 and test27. (perform): Check members of spec, rather than locals with same name, when deciding to terminate testing early; fix some code whitespace. * tests/data/test-read-dwarf/test14-pr18893.so.abi: Update multidimensional array sizes. * tests/data/test-read-dwarf/test17-pr19027.so.abi: Ditto. * tests/data/test-read-dwarf/test19-pr19023-libtcmalloc_and_profiler.so.abi: Ditto. * tests/data/test-read-dwarf/test7.so.abi: Ditto. * tests/data/test-read-dwarf/PR25042-libgdbm-clang-dwarf5.so.6.0.0.abi: Update following translation unit ordering change. * tests/data/test-read-dwarf/test13-pr18894.so.abi: Ditto. * tests/data/test-read-dwarf/test14-pr18893.so.abi: Ditto. * tests/data/test-read-dwarf/test15-pr18892.so.abi: Ditto. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Ditto. * tests/data/test-read-dwarf/test17-pr19027.so.abi: Ditto. * tests/data/test-read-dwarf/test18-pr19037-libvtkRenderingLIC-6.1.so.abi: Ditto. * tests/data/test-read-dwarf/test19-pr19023-libtcmalloc_and_profiler.so.abi: Ditto. * tests/data/test-read-dwarf/test20-pr19025-libvtkParallelCore-6.1.so.abi: Ditto. * tests/data/test-read-dwarf/test21-pr19092.so.abi: Ditto. * tests/data/test-read-dwarf/test22-pr19097-libstdc++.so.6.0.17.so.abi: Ditto. * tests/data/test-read-dwarf/PR25007-sdhci.ko.abi: Update following code changes affecting ordering of some ABI elements. * tests/data/test-read-dwarf/test16-pr18904.so.abi Reviewed-by: Matthias Maennich <maennich@google.com> Tested-by: Matthias Maennich <maennich@google.com> Signed-off-by: Giuliano Procida <gprocida@google.com>
