From: Tom Tromey Date: Wed, 30 Sep 2020 00:49:08 +0000 (-0600) Subject: Change some uses of DW_STRING to string method X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2c830f5475;p=binutils-gdb.git Change some uses of DW_STRING to string method This changes some of the simpler spots to use attribute::string rather than DW_STRING. gdb/ChangeLog 2020-09-29 Tom Tromey * dwarf2/read.c (partial_die_info::read) (dwarf2_const_value_attr, anonymous_struct_prefix, ) (dwarf2_name, dwarf2_fetch_constant_bytes): Use attribute::as_string. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index b78cffe5978..f6e0138713f 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,10 @@ +2020-09-29 Tom Tromey + + * dwarf2/read.c (partial_die_info::read) + (dwarf2_const_value_attr, anonymous_struct_prefix, ) + (dwarf2_name, dwarf2_fetch_constant_bytes): Use + attribute::as_string. + 2020-09-29 Tom Tromey * dwarf2/attribute.c (attribute::address): Don't use DW_UNSND or diff --git a/gdb/dwarf2/read.c b/gdb/dwarf2/read.c index 2e5b7e28deb..70d20911487 100644 --- a/gdb/dwarf2/read.c +++ b/gdb/dwarf2/read.c @@ -19017,11 +19017,11 @@ partial_die_info::read (const struct die_reader_specs *reader, /* These tags always have simple identifiers already; no need to canonicalize them. */ canonical_name = 1; - raw_name = DW_STRING (&attr); + raw_name = attr.as_string (); break; default: canonical_name = 0; - raw_name = DW_STRING (&attr); + raw_name = attr.as_string (); break; } break; @@ -21863,7 +21863,7 @@ dwarf2_const_value_attr (const struct attribute *attr, struct type *type, case DW_FORM_GNU_strp_alt: /* DW_STRING is already allocated on the objfile obstack, point directly to it. */ - *bytes = (const gdb_byte *) DW_STRING (attr); + *bytes = (const gdb_byte *) attr->as_string (); break; case DW_FORM_block1: case DW_FORM_block2: @@ -22307,21 +22307,22 @@ anonymous_struct_prefix (struct die_info *die, struct dwarf2_cu *cu) return NULL; attr = dw2_linkage_name_attr (die, cu); - if (attr == NULL || DW_STRING (attr) == NULL) + const char *attr_name = attr->as_string (); + if (attr == NULL || attr_name == NULL) return NULL; /* dwarf2_name had to be already called. */ gdb_assert (DW_STRING_IS_CANONICAL (attr)); /* Strip the base name, keep any leading namespaces/classes. */ - base = strrchr (DW_STRING (attr), ':'); - if (base == NULL || base == DW_STRING (attr) || base[-1] != ':') + base = strrchr (attr_name, ':'); + if (base == NULL || base == attr_name || base[-1] != ':') return ""; struct objfile *objfile = cu->per_objfile->objfile; return obstack_strndup (&objfile->per_bfd->storage_obstack, - DW_STRING (attr), - &base[-1] - DW_STRING (attr)); + attr_name, + &base[-1] - attr_name); } /* Return the name of the namespace/class that DIE is defined within, @@ -22588,7 +22589,8 @@ dwarf2_name (struct die_info *die, struct dwarf2_cu *cu) struct objfile *objfile = cu->per_objfile->objfile; attr = dwarf2_attr (die, DW_AT_name, cu); - if ((!attr || !DW_STRING (attr)) + const char *attr_name = attr == nullptr ? nullptr : attr->as_string (); + if (attr_name == nullptr && die->tag != DW_TAG_namespace && die->tag != DW_TAG_class_type && die->tag != DW_TAG_interface_type @@ -22606,11 +22608,11 @@ dwarf2_name (struct die_info *die, struct dwarf2_cu *cu) case DW_TAG_enumerator: /* These tags always have simple identifiers already; no need to canonicalize them. */ - return DW_STRING (attr); + return attr_name; case DW_TAG_namespace: - if (attr != NULL && DW_STRING (attr) != NULL) - return DW_STRING (attr); + if (attr_name != nullptr) + return attr_name; return CP_ANONYMOUS_NAMESPACE_STR; case DW_TAG_class_type: @@ -22621,25 +22623,25 @@ dwarf2_name (struct die_info *die, struct dwarf2_cu *cu) structures or unions.
