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.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
