Add support for abicompat weak mode This patch implements the weak mode of abicompat. In this mode, just the application and the new version of the library are provided. The types of functions and variables of the library that are consumed by the application are compared to the types of the functions and variables expected by the application. The goal is to check if the types of the declarations consumed by the application and provided by the library are compatible with what the application expects. The abicompat first gets the set of symbols undefined in the application and exported by the library. It then builds the set of declarations exported by the library that have those symbols. We call these the set of declarations of the library that are consumed by the application. Note that the debug information for the application does not contain the declarations of the functions/variables whose symbols are undefined. So we can not just read them to compare them to declarations exported by the library. But the *types* of the variables and the *sub-types* of the functions whose symbols are undefined in the application are present in the debug information of the application. So in the weak mode, abicompat compare the *types* of the declarations consumed by the application as expected by the application (described by the debug information of the application) with the types of the declarations exported by the library. To do this a number of changes were necessary. The patch builds a representation of all the types found in the application's debug info. Before that, only the types that are reachable from exported declarations were represented. The abidw tool got a new --load-all-types to test this new ability of loading all types. The patch also adds support for looking a type, not by name, but by its internal representation. In the comparison engine, function_type_diff is introduced to represent changes between two function types. For this, a new class type_or_decl_base has been introduced in the IR. It's now the base class for both decl_base and type_base. And abigail::comparison::diff now takes two pointers of type_or_decl, not decl_base anymore. So function_type_diff can take two function_type now; not that a function_type has no declaration so it doesn't inherit decl_base. A bunch of changes got made just to adjust to this modification. A number of fixes were made too, to make this work, like adding missing comparison operators, removing asserts that too strong, etc.. The patch also adjust the test suite as well as the documentation. * include/abg-fwd.h (class type_or_decl_base): Forward declare this. (is_decl, is_type, is_function_type, get_name, get_type_name) (get_function_type_name, get_pretty_representation) (lookup_function_type_in_corpus, lookup_type_in_translation_unit) (lookup_function_type_in_translation_unit) (synthesize_function_type_from_translation_unit) (hash_type_or_decl): New function declarations. * src/abg-corpus.cc (lookup_type_in_corpus) (lookup_function_type_in_corpus): Define new functions. * include/abg-ir.h (translation_unit::lookup_function_type_in_translation_unit): Declare new friend function.

Add support for abicompat weak mode This patch implements the weak mode of abicompat. In this mode, just the application and the new version of the library are provided. The types of functions and variables of the library that are consumed by the application are compared to the types of the functions and variables expected by the application. The goal is to check if the types of the declarations consumed by the application and provided by the library are compatible with what the application expects. The abicompat first gets the set of symbols undefined in the application and exported by the library. It then builds the set of declarations exported by the library that have those symbols. We call these the set of declarations of the library that are consumed by the application. Note that the debug information for the application does not contain the declarations of the functions/variables whose symbols are undefined. So we can not just read them to compare them to declarations exported by the library. But the *types* of the variables and the *sub-types* of the functions whose symbols are undefined in the application are present in the debug information of the application. So in the weak mode, abicompat compare the *types* of the declarations consumed by the application as expected by the application (described by the debug information of the application) with the types of the declarations exported by the library. To do this a number of changes were necessary. The patch builds a representation of all the types found in the application's debug info. Before that, only the types that are reachable from exported declarations were represented. The abidw tool got a new --load-all-types to test this new ability of loading all types. The patch also adds support for looking a type, not by name, but by its internal representation. In the comparison engine, function_type_diff is introduced to represent changes between two function types. For this, a new class type_or_decl_base has been introduced in the IR. It's now the base class for both decl_base and type_base. And abigail::comparison::diff now takes two pointers of type_or_decl, not decl_base anymore. So function_type_diff can take two function_type now; not that a function_type has no declaration so it doesn't inherit decl_base. A bunch of changes got made just to adjust to this modification. A number of fixes were made too, to make this work, like adding missing comparison operators, removing asserts that too strong, etc.. The patch also adjust the test suite as well as the documentation. * include/abg-fwd.h (class type_or_decl_base): Forward declare this. (is_decl, is_type, is_function_type, get_name, get_type_name) (get_function_type_name, get_pretty_representation) (lookup_function_type_in_corpus, lookup_type_in_translation_unit) (lookup_function_type_in_translation_unit) (synthesize_function_type_from_translation_unit) (hash_type_or_decl): New function declarations. * src/abg-corpus.cc (lookup_type_in_corpus) (lookup_function_type_in_corpus): Define new functions. * include/abg-ir.h (translation_unit::lookup_function_type_in_translation_unit): Declare new friend function.
