From: Dodji Seketeli Date: Fri, 3 Feb 2023 00:15:41 +0000 (+0100) Subject: PR30048 - wrong pretty representation of qualified pointers X-Git-Tag: upstream/2.3~64 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=03d8b52fc7a510edaf3182a3600cc54c0a180fe7;p=platform%2Fupstream%2Flibabigail.git PR30048 - wrong pretty representation of qualified pointers A qualified type is textually represented as the following: were "qualifier" is the qualifier carried by the qualified type and "underlying-type" is the type being qualified. In this case, the qualifier prefixes the textual representation of the qualified type. This is true if the underlying type of the qualified type is a non-const, non-reference type. For instance: const int; But when the underlying type is a pointer, then the qualified type is represented as: int* const; In that later case, the qualifier comes /after/ the textual representation of the underlying type. Now suppose the underlying type is itself a qualified type. In that case, for a non-const underlying type, we'd have, e.g: const volatile int; where the qualifier precedes the qualified type (which is itself a qualified type) /IF/ the ultimate underlying type (a.k.a the leaf underlying type) is itself a non-const, non-reference type. But if the ultimate underlying type is a pointer, a qualified type with an underlying qualified type would be textually represented as, e.g: int* const volatile; In other words, if the leaf type is a pointer, the qualifier suffixes the textual representation the underlying qualified type. Libabigail is failing to apply this later rule. As the type name is used as a key to cache IR nodes of DIEs (among other things), getting it wrong can lead to a bumpy ride down the road. Fixed thus. * src/abg-dwarf-reader.cc (die_is_pointer_array_or_reference_type): Rename die_is_pointer_or_reference_type into this. This new name reflects more what the function does as it tests if a DIE is for pointer, an array or a reference. (pointer_or_qual_die_of_anonymous_class_type): Adjust to use the newly (and better) named die_is_pointer_array_or_reference_type. (die_is_pointer_or_reference_type): Make this really test if a DIE is for a pointer or a reference. Now the name matches what the function does. (die_peel_qualified): Define new function. (die_qualified_type_name): When a qualified name Q has another qualified name as its underlying type, it's important to know if the leaf type is a pointer type or not to know how to construct the name of Q. This change now peels the potential qualifiers from the underlying type of the qualified type to see if the leaf type is a pointer or not. * src/abg-ir.cc (get_name_of_qualified_type): Likewise. Also, the name of array types doesn't follow the same rule as for pointers and references. * tests/data/test-abidiff-exit/PR30048-test-report-0.txt: Add new reference test output. * tests/data/test-abidiff-exit/PR30048-test-2-report-1.txt: Likewise. * tests/data/test-abidiff-exit/PR30048-test-v{0,1}.c: Add source code of binary input data. * tests/data/test-abidiff-exit/PR30048-test-2-v{0,1}.cc: Likewise. * tests/data/test-abidiff-exit/PR30048-test-v{0,1}.o: Add binary input data. * tests/data/test-abidiff-exit/PR30048-test-2-v{0,1}.o: Likewise. * tests/data/Makefile.am: Add the new test material above to source distribution. * tests/test-abidiff-exit.cc (in_out_specs): Add the input binaries to this test harness. * tests/data/test-abidiff-exit/qualifier-typedef-array-report-1.txt: Adjust.
