From f55ee35cf17f1eb104292b4c6b2f7def38ffe4a8 Mon Sep 17 00:00:00 2001 From: Jan Kratochvil Date: Wed, 2 Jun 2010 22:41:56 +0000 Subject: gdb/ Support DW_TAG_module as separate namespaces. * dwarf2read.c (typename_concat): New parameter physname. (read_module_type): New function and declaration. (scan_partial_symbols): Scan also DW_TAG_module children. (partial_die_parent_scope): Accept scope even from DW_TAG_module. Pass to typename_concat backward compatible physname value 0. (partial_die_full_name, read_namespace_type): Pass to typename_concat backward compatible physname value 0. (add_partial_module, read_module): Remove FIXME comment. (process_die) : Set PROCESSING_HAS_NAMESPACE_INFO. (die_needs_namespace) : Allow returning true even for DIEs under DW_TAG_module. (dwarf2_compute_name): Move the ada block for DW_AT_linkage_name and DW_AT_MIPS_linkage_name first, extend it for language_fortran && physname and return there instead of just setting NAME. Extend the main block for language_fortran. Pass physname parameter to the typename_concat call. (read_import_statement, read_func_scope, get_scope_pc_bounds) (load_partial_dies, determine_prefix): Support also DW_TAG_module. (new_symbol): Fill in cplus_specific.demangled_name if it is still missing from SYMBOL_SET_NAMES in the language_fortran case. (new_symbol) : Force LOC_UNRESOLVED for gfortran module variables. (read_type_die) : New. (MAX_SEP_LEN): Increase to 7. (typename_concat): New parameter physname. New variable lead. Support also language_fortran. * f-exp.y (yylex): Consider : also as a symbol name character class. * f-lang.c: Include cp-support.h. (f_word_break_characters, f_make_symbol_completion_list): New functions. (f_language_defn): Use cp_lookup_symbol_nonlocal, f_word_break_characters and f_make_symbol_completion_list. * f-typeprint.c (f_type_print_base) : New. * gdbtypes.h (enum type_code) : New. * symtab.c (symbol_init_language_specific): Support language_fortran. (symbol_find_demangled_name): New comment on language_fortran. (symbol_natural_name, symbol_demangled_name): Use demangled_name even for language_fortran. (lookup_symbol_aux_local): Check imports also for language_fortran. (default_make_symbol_completion_list): Rename to ... (default_make_symbol_completion_list_break_on): ... this name. New parameter break_on, use it. (default_make_symbol_completion_list): New stub. * symtab.h (default_make_symbol_completion_list_break_on): New prototype. gdb/testsuite/ Support DW_TAG_module as separate namespaces. * gdb.fortran/library-module.exp, gdb.fortran/library-module-main.f90, gdb.fortran/library-module-lib.f90: New. * gdb.fortran/module.exp: Replace startup by a prepare_for_testing call. (print i): Remove. (continue to breakpoint: i-is-1, print var_i value 1) (continue to breakpoint: i-is-2, print var_i value 2) (continue to breakpoint: a-b-c-d, print var_a, print var_b, print var_c) (print var_d, print var_i value 14, ptype modmany, complete `modm) (complete `modmany, complete `modmany`, complete `modmany`var) (show language, setting breakpoint at module): New tests. * gdb.fortran/module.f90 (module mod): Remove. (module mod1, module mod2, module modmany, subroutine sub1) (subroutine sub2, program module): New. --- gdb/f-lang.c | 39 ++++++++++++++++++++++++++++++++++++--- 1 file changed, 36 insertions(+), 3 deletions(-) (limited to 'gdb/f-lang.c') diff --git a/gdb/f-lang.c b/gdb/f-lang.c index 0b86035..cad8cfb 100644 --- a/gdb/f-lang.c +++ b/gdb/f-lang.c @@ -31,6 +31,7 @@ #include "f-lang.h" #include "valprint.h" #include "value.h" +#include "cp-support.h" /* Following is dubious stuff that had been in the xcoff reader. */ @@ -308,6 +309,38 @@ f_language_arch_info (struct gdbarch *gdbarch, lai->bool_type_default = builtin->builtin_logical_s2; } +/* Remove the modules separator :: from the default break list. */ + +static char * +f_word_break_characters (void) +{ + static char *retval; + + if (!retval) + { + char *s; + + retval = xstrdup (default_word_break_characters ()); + s = strchr (retval, ':'); + if (s) + { + char *last_char = &s[strlen (s) - 1]; + + *s = *last_char; + *last_char = 0; + } + } + return retval; +} + +/* Consider the modules separator :: as a valid symbol name character class. */ + +static char ** +f_make_symbol_completion_list (char *text, char *word) +{ + return default_make_symbol_completion_list_break_on (text, word, ":"); +} + /* This is declared in c-lang.h but it is silly to import that file for what is already just a hack. */ extern int c_value_print (struct value *, struct ui_file *, @@ -335,15 +368,15 @@ const struct language_defn f_language_defn = c_value_print, /* FIXME */ NULL, /* Language specific skip_trampoline */ NULL, /* name_of_this */ - basic_lookup_symbol_nonlocal, /* lookup_symbol_nonlocal */ + cp_lookup_symbol_nonlocal, /* lookup_symbol_nonlocal */ basic_lookup_transparent_type,/* lookup_transparent_type */ NULL, /* Language specific symbol demangler */ NULL, /* Language specific class_name_from_physname */ f_op_print_tab, /* expression operators for printing */ 0, /* arrays are first-class (not c-style) */ 1, /* String lower bound */ - default_word_break_characters, - default_make_symbol_completion_list, + f_word_break_characters, + f_make_symbol_completion_list, f_language_arch_info, default_print_array_index, default_pass_by_reference, -- cgit v1.1
