2017-08-30[4/77] Add FOR_EACH iterators for modesRichard Sandiford1-4/+2
The new iterators are: - FOR_EACH_MODE_IN_CLASS: iterate over all the modes in a mode class. - FOR_EACH_MODE_FROM: iterate over all the modes in a class, starting at a given mode. - FOR_EACH_WIDER_MODE: iterate over all the modes in a class, starting at the next widest mode after a given mode. - FOR_EACH_2XWIDER_MODE: same, but considering only modes that are two times wider than the previous mode. - FOR_EACH_MODE_UNTIL: iterate over all the modes in a class until a given mode is reached. - FOR_EACH_MODE: iterate over all the modes in a class between two given modes, inclusive of the first but not the second. These help with the stronger type checking added by later patches, since every new mode will be in the same class as the previous one. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (mode_traits): New structure.

2015-12-17DWARF: add a language hook to override types in debugging informationPierre-Marie de Rodat1-0/+53
Many artificial types are introduced by GNAT in order to satisfy constraints in GCC's internal trees or to generate optimal code. These hide original types from sources and miss useful information in the debugging information or add noise to it and make debugging confusing. This change introduces a new language hook to give a chance to front-ends to restore the source types in the debugging information. This change also enhance the array descriptor language hook to handle array-wide bit/byte stride. Some arrays may contain dynamically-sized objects. Debuggers need for these a hint to know the size allocated for each element, hence the need for the array-wide bit/byte stride. The Ada front-end is enhanced to take advantage of both hooks when -fgnat-encodings=minimal, in order to keep compatibility with GDB. gcc/ada/ChangeLog: * gcc-interface/ada-tree.h (struct lang_type): Rename the t field as t1 and add a t2 one. (get_lang_specific): New. (GET_TYPE_LANG_SPECIFIC): Refactor to use get_lang_specific. (SET_TYPE_LANG_SPECIFIC): Likewise. (GET_TYPE_LANG_SPECIFIC2): New macro. (SET_TYPE_LANG_SPECIFIC2): New macro. (TYPE_DEBUG_TYPE): New macro. (SET_TYPE_DEBUG_TYPE): New macro. * gcc-interface/decl.c (gnat_to_gnu_entity): When -fgnat-encodings=minimal, set padding types' debug type to the padded one (i.e. strip ___PAD GNAT encodings) and set constrained record subtypes's debug type to the base type. * gcc-interface/misc.c (gnat_print_type): Print debug types. (gnat_get_debug_type): New. (gnat_get_array_descr_info): When -fgnat-encodings=minimal, set a byte stride for arrays that contain a type whose debug type has variable length. (LANG_HOOKS_GET_DEBUG_TYPE): Redefine macro to implement the debug type language hook. * gcc-interface/utils.c (maybe_pad_type): When -fgnat-encodings=minimal, set padding types' debug type to the padded one. Restore XVZ variables creation when -fgnat-encodings-minimal and use them to hold padding types' byte size. For library-level padding types, share this variable across translation units. Tag XVZ variables as artificial. gcc/ChangeLog: * langhooks.h (struct lang_hooks_for_types): Add a get_debug_type field. * langhooks-def.h (LANG_HOOKS_GET_DEBUG_TYPE): New macro. (LANG_HOOKS_FOR_TYPES_INITIALIZER): Initialize the get_debug_type field. * dwarf2out.h (struct array_descr_info): Add an array-wide stride field. * dwarf2out.c (modified_type_die): Invoke the get_debug_type language hook, process its result instead, if any. (gen_descr_array_type_die): Add array-wide stride processing. From-SVN: r231763
