D language support.
gdb/ChangeLog: D language support. * Makefile.in (SFILES): Add d-lang.c d-valprint.c. (COMMON_OBS): Add d-lang.o d-valprint.o. (HFILES_NO_SRCDIR): Add d-lang.h. * NEWS: Mention D language support. * c-lang.c (c_emit_char, exp_descriptor_c): Make public. * c-lang.h (c_emit_char, exp_descriptor_c): Add declaration. * d-lang.c: New file. * d-lang.h: New file. * d-valprint.c: New file. * defs.h (enum language): Add language_d. * dwarf2read.c (set_cu_language): Add DW_LANG_D. * language.c (binop_result_type, integral_type, character_type) (string_type, boolean_type, structured_type): Add language_d. * symfile.c (init_filename_language_table): Add language_d. * symtab.c: Include d-lang.h. (symbol_init_language_specific, symbol_find_demangled_name) (symbol_natural_name, lookup_symbol_in_language) (symbol_demangled_name, symbol_matches_domain): Add language_d. gdb/doc/ChangeLog: * gdb.texinfo: (Summary) Add mention about D language support. (Filenames): Add D suffixes. (D): New node. gdb/testsuite/ChangeLog: * gdb.base/default.exp: Fix "set language" test.
