2020-11-19Enhance debug info for fixed-point typesEric Botcazou1-12/+2
The Ada language supports fixed-point types as first-class citizens so they need to be described as-is in the debug info. We devised the langhook get_fixed_point_type_info for this purpose a few years ago, but it comes with a limitation for the representation of the scale factor that we would need to lift in order to be able to represent more fixed-point types. gcc/ChangeLog: * dwarf2out.h (struct fixed_point_type_info) <scale_factor>: Turn numerator and denominator into a tree. * dwarf2out.c (base_type_die): In the case of a fixed-point type with arbitrary scale factor, call add_scalar_info on numerator and denominator to emit the appropriate attributes. gcc/ada/ChangeLog: * exp_dbug.adb (Is_Handled_Scale_Factor): Delete. (Get_Encoded_Name): Do not call it. * gcc-interface/decl.c (gnat_to_gnu_entity) <Fixed_Point_Type>: Tidy up and always use a meaningful description for arbitrary scale factors. * gcc-interface/misc.c (gnat_get_fixed_point_type_info): Remove obsolete block and adjust the description of the scale factor.
2020-11-07Ada : Fix bootstrap after r11-4793.Iain Sandoe1-1/+1
The patch omitted a change for Ada, fixed thus. gcc/ada/ChangeLog: * gcc-interface/misc.c (gnat_printable_name): Change DECL_IS_BUILTIN -> DECL_IS_UNDECLARED_BUILTIN.
2020-09-11Add missing stride entry in debug infoEric Botcazou1-0/+4
This adds a missing stride entry for bit-packed arrays of record types. gcc/ada/ChangeLog: * gcc-interface/misc.c (get_array_bit_stride): Return TYPE_ADA_SIZE for record and union types.
2020-09-11Drop GNAT encodings for fixed-point typesEric Botcazou1-3/+2
GDB can now deal with the DWARF representation just fine. gcc/ada/ChangeLog: * gcc-interface/misc.c (gnat_get_fixed_point_type): Bail out only when the GNAT encodings are specifically used.
2020-09-10Add emergency dump after an ICEEric Botcazou1-0/+4
This is only for internal debugging purposes. gcc/ada/ChangeLog: * gcc-interface/misc.c: Include tree-pass.h. (internal_error_function): Call emergency_dump_function.
2020-06-23Streamline implementation of renaming in gigiEric Botcazou1-3/+0
The main changes are 1) the bulk of the implementation is put back entirely in gnat_to_gnu_entity and 2) the handling of lvalues is unified, i.e. it no longer depends on the Materialize_Entity flag being present on the entity. gcc/ada/ChangeLog: * gcc-interface/ada-tree.h (DECL_RENAMED_OBJECT): Delete. * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Always use the stabilized reference directly for renaming and create a variable pointing to it separately if requested. * gcc-interface/misc.c (gnat_print_decl): Adjust for deletion. * gcc-interface/trans.c (Identifier_to_gnu): Likewise. (gnat_to_gnu) <N_Object_Renaming_Declaration>: Do not deal with side-effects here. <N_Exception_Renaming_Declaration>: Likewise.
2020-06-19[Ada] AI12-0028-1 Import of variadic C functionsEric Botcazou1-0/+1
2020-06-19 Eric Botcazou <ebotcazou@adacore.com> gcc/ada/ * gcc-interface/decl.c (gnat_to_gnu_param): Tidy up. (gnat_to_gnu_subprog_type): For a variadic C function, do not build unnamed parameters and do not add final void node. * gcc-interface/misc.c: Include snames.h. * gcc-interface/trans.c (Attribute_to_gnu): Tidy up. (Call_to_gnu): Implement support for unnamed parameters in a variadic C function. * gcc-interface/utils.c: Include snames.h. (copy_type): Tidy up.
2020-06-04[Ada] Remove OpenACC supportArnaud Charlet1-1/+0

2020-05-25Change description of fat pointertype with -fgnat-encodings=minimalEric Botcazou1-44/+10
This makes a step back in the representation of fat pointer types in the debug info with -fgnat-encodings=minimal so as to avoid hiding the data indirection and making it easiser to synthetize the construct. gcc/ada/ChangeLog * gcc-interface/decl.c (gnat_to_gnu_entity) <E_Array_Type>: Add a description of the various types associated with the unconstrained type. Declare the fat pointer earlier. Set the current function as context on the template type, and the fat pointer type on the array type. Always mark the fat pointer type as artificial and set it as the context for the pointer type to the array. Also reuse GNU_ENTITY_NAME. Finish up the unconstrained type at the very end. * gcc-interface/misc.c (gnat_get_array_descr_info): Do not handle fat pointer types and tidy up accordingly. * gcc-interface/utils.c (build_unc_object_type): Do not set the context on the template type.

2019-11-06introduce -fcallgraph-info optionEric Botcazou1-3/+0
This was first submitted many years ago https://gcc.gnu.org/ml/gcc-patches/2010-10/msg02468.html The command line option -fcallgraph-info is added and makes the compiler generate another output file (xxx.ci) for each compilation unit (or LTO partitoin), which is a valid VCG file (you can launch your favorite VCG viewer on it unmodified) and contains the "final" callgraph of the unit. "final" is a bit of a misnomer as this is actually the callgraph at RTL expansion time, but since most high-level optimizations are done at the Tree level and RTL doesn't usually fiddle with calls, it's final in almost all cases. Moreover, the nodes can be decorated with additional info: -fcallgraph-info=su adds stack usage info and -fcallgraph-info=da dynamic allocation info. for gcc/ChangeLog From Eric Botcazou <ebotcazou@adacore.com>, Alexandre Oliva <oliva@adacore.com> * common.opt (-fcallgraph-info[=]): New option. * doc/invoke.texi (Developer options): Document it. * opts.c (common_handle_option): Handle it. * builtins.c (expand_builtin_alloca): Record allocation if -fcallgraph-info=da. * calls.c (expand_call): If -fcallgraph-info, record the call.

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.
