Fixes this in C++ mode:
gdb/gdbserver/tracepoint.c: In function ‘void* gdb_agent_helper_thread(void*)’:
gdb/gdbserver/tracepoint.c:7190:47: error: cannot convert ‘sockaddr_un*’ to ‘sockaddr*’ for argument ‘2’ to ‘int accept(int, sockaddr*, socklen_t*)’
fd = accept (listen_fd, &sockaddr, &tmp);
gdb/gdbserver/ChangeLog:
2015-03-09 Pedro Alves <palves@redhat.com>
* tracepoint.c (gdb_agent_helper_thread): Cast '&sockaddr' to
'struct sockaddr' pointer in 'accept' call.
const works different in C vs C++. In C++, a global "const" variable
has internal linkage by default, resulting in link errors like:
...
extension.o: In function `get_ext_lang_defn(extension_language)':
gdb/extension.c:126: undefined reference to `extension_language_guile'
gdb/extension.c:124: undefined reference to `extension_language_guile'
...
The fix is to define exported const objects with "extern const". But
that in C would not be a definition. So we need to #ifdef C vs C++ in
this case.
EXPORTED_CONST comes from include/ansidecl.h, but in the
feature_to_c.sh case I think it's better to leave the script with no
dependencies.
gdb/ChangeLog:
2015-02-27 Pedro Alves <palves@redhat.com>
* cp-valprint.c (vtbl_ptr_name): Use EXPORTED_CONST.
* guile/guile.c (extension_language_guile): Use EXPORTED_CONST.
* features/feature_to_c.sh: Tag the generated xml_builtin array
with extern const in C++ mode.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
(COMMON_OBS): Add xml-builtin.o.
(xml-builtin.c, stamp-xml): New rules.
(xml-tdesc.o): Update.
* features/feature_to_c.sh: New file.
* xml-support.c (MAX_XINCLUDE_DEPTH): Define.
(struct gdb_xml_parser): Add dtd_name and is_xinclude.
(gdb_xml_start_element): Initialize scope after possibly reallocating
scopes. Move cleanup later. Handle the XInclude description
specially.
(gdb_xml_end_element): Only parse the body if there is a current element.
Call XML_DefaultCurrent if there is no element.
(gdb_xml_fetch_external_entity, gdb_xml_use_dtd): New.
(struct xinclude_parsing_data, xinclude_start_include)
(xinclude_end_include, xml_xinclude_default)
(xml_xinclude_start_doctype, xml_xinclude_end_doctype)
(xml_xinclude_xml_decl, xml_xinclude_cleanup, xinclude_attributes)
(xinclude_elements, xml_process_xincludes, fetch_xml_builtin): New.
* xml-support.h (xml_fetch_another, xml_process_xincludes)
(fetch_xml_builtin, xml_builtin, gdb_xml_use_dtd): New declarations.
* xml-tdesc.c (tdesc_parse_xml): Add fetcher_baton argument. Expand
XInclude directives. Use the compiled in DTD.
(fetch_xml_from_file): Add baton argument. Treat it as a containing
directory name. Do not warn here.
(file_read_description_xml): Update call. Warn here instead. Pass
a dirname as baton.
(fetch_available_features_from_target): New.
(target_read_description_xml): Use it.
* features/gdb-target.dtd: Add copyright notice. Use xinclude.dtd
to handle XInclude.
* features/xinclude.dtd: New file.
* gdb.xml/bad-include.xml, gdb.xml/inc-2.xml, gdb.xml/inc-body.xml,
gdb.xml/includes.xml, gdb.xml/tdesc-xinclude.exp: New files.
* gdb.texinfo (Target Description Format): Add section on XInclude.
