remove gdb_string.h
This removes gdb_string.h. This patch is purely mechanical. I
created it by running the two commands:
git rm common/gdb_string.h
perl -pi -e's/"gdb_string.h"/<string.h>/;' *.[chyl] */*.[chyl]

GDB/MI: Add new "--language LANG" command option.
Frontend sometimes need to evaluate expressions that are
language-specific. For instance, Eclipse uses the following
expression to determine the size of an address on the target:
-data-evaluate-expression "sizeof (void*)"
Unfortunately, if the main of the program being debugged is not C,
this may not work. For instance, if the main is in Ada, you get...
-data-evaluate-expression "sizeof (void*)"
^error,msg="No definition of \"sizeof\" in current context."
... and apparently decides to stop the debugging session as a result.
The recommendation sent was to specifically set the language to C
before trying to evaluate the expression. Something such as:
1. save current language
2. set language c
3. -data-evaluate-expression "sizeof (void*)"
4. Restore language
This has the same disadvantages as the ones outlined in the "Context
Management" section of the GDB/MI documentation regarding setting
the current thread or the current frame, thus recommending the use of
general command-line switches such as --frame, or --thread instead.
This patch follows the same steps for the language, adding a similar
new command option: --language LANG. Example of use:
-data-evaluate-expression --language c "sizeof (void*)"
^done,value="4"
gdb/ChangeLog:
* mi/mi-parse.h (struct mi_parse) <language>: New field.
* mi/mi-main.c (mi_cmd_execute): Temporarily set language to
PARSE->LANGUAGE during command execution, if set.
* mi/mi-parse.c: Add "language.h" #include.
(mi_parse): Add parsing of "--language" command option.
* NEWS: Add entry mentioning the new "--language" command option.
gdb/testsuite/ChangeLog:
* gdb.mi/mi-language.exp: New file.
gdb/doc/ChangeLog:
* gdb.texinfo (Show): Add xref anchor for "show language" command.
(Context management): Place current subsection text into its own
subsubsection. Add new subsubsection describing the "--language"
command option.

add -Wold-style-declaration
This adds -Wold-style-declaration to gdb's list of warnings.
It turns out that a few places use "const static" rather than
"static const". The former is deprecated according to the C standard.
Tested by rebuilding with --enable-targets=all on x86-64 Fedora 18.
* configure.ac (build_warnings): Add -Wold-style-declaration.
* configure: Rebuild.
* dsrec.c (make_srec): Use "static const", not "const static".
* h8300-tdep.c (h8300_breakpoint_from_pc): Use "static const",
not "const static".
* mi/mi-parse.c (mi_no_values, mi_simple_values, mi_all_values):
Use "static const", not "const static".
* mn10300-tdep.c (mn10300_breakpoint_from_pc): Use "static const",
not "const static".
* moxie-tdep.c (moxie_breakpoint_from_pc): Use "static const",
not "const static".
* rs6000-tdep.c (rs6000_breakpoint_from_pc): Use "static const",
not "const static".
* v850-tdep.c (v850_breakpoint_from_pc): Use "static const",
not "const static".
(v850_dbtrap_breakpoint_from_pc): Likewise.
* xstormy16-tdep.c (xstormy16_breakpoint_from_pc): Use "static const",
not "const static".

GDB/MI: Add new "--language LANG" command option.
Frontend sometimes need to evaluate expressions that are
language-specific. For instance, Eclipse uses the following
expression to determine the size of an address on the target:
-data-evaluate-expression "sizeof (void*)"
Unfortunately, if the main of the program being debugged is not C,
this may not work. For instance, if the main is in Ada, you get...
-data-evaluate-expression "sizeof (void*)"
^error,msg="No definition of \"sizeof\" in current context."
... and apparently decides to stop the debugging session as a result.
The recommendation sent was to specifically set the language to C
before trying to evaluate the expression. Something such as:
1. save current language
2. set language c
3. -data-evaluate-expression "sizeof (void*)"
4. Restore language
This has the same disadvantages as the ones outlined in the "Context
Management" section of the GDB/MI documentation regarding setting
the current thread or the current frame, thus recommending the use of

GDB/MI: Add new "--language LANG" command option.
Frontend sometimes need to evaluate expressions that are
language-specific. For instance, Eclipse uses the following
expression to determine the size of an address on the target:
-data-evaluate-expression "sizeof (void*)"
Unfortunately, if the main of the program being debugged is not C,
this may not work. For instance, if the main is in Ada, you get...
-data-evaluate-expression "sizeof (void*)"
^error,msg="No definition of \"sizeof\" in current context."
... and apparently decides to stop the debugging session as a result.
The recommendation sent was to specifically set the language to C
before trying to evaluate the expression. Something such as:
1. save current language
2. set language c
3. -data-evaluate-expression "sizeof (void*)"
4. Restore language
This has the same disadvantages as the ones outlined in the "Context
Management" section of the GDB/MI documentation regarding setting
the current thread or the current frame, thus recommending the use of
general command-line switches such as --frame, or --thread instead.
This patch follows the same steps for the language, adding a similar
new command option: --language LANG. Example of use:
-data-evaluate-expression --language c "sizeof (void*)"
^done,value="4"

GDB/MI: Add new "--language LANG" command option.
Frontend sometimes need to evaluate expressions that are
language-specific. For instance, Eclipse uses the following
expression to determine the size of an address on the target:
-data-evaluate-expression "sizeof (void*)"
Unfortunately, if the main of the program being debugged is not C,
this may not work. For instance, if the main is in Ada, you get...
-data-evaluate-expression "sizeof (void*)"
^error,msg="No definition of \"sizeof\" in current context."
... and apparently decides to stop the debugging session as a result.
The recommendation sent was to specifically set the language to C
before trying to evaluate the expression. Something such as:
1. save current language
2. set language c
3. -data-evaluate-expression "sizeof (void*)"
4. Restore language
This has the same disadvantages as the ones outlined in the "Context
Management" section of the GDB/MI documentation regarding setting
the current thread or the current frame, thus recommending the use of
general command-line switches such as --frame, or --thread instead.
This patch follows the same steps for the language, adding a similar
new command option: --language LANG. Example of use:
-data-evaluate-expression --language c "sizeof (void*)"
^done,value="4"
gdb/ChangeLog:
* mi/mi-parse.h (struct mi_parse) <language>: New field.
* mi/mi-main.c (mi_cmd_execute): Temporarily set language to
PARSE->LANGUAGE during command execution, if set.
* mi/mi-parse.c: Add "language.h" #include.
(mi_parse): Add parsing of "--language" command option.
* NEWS: Add entry mentioning the new "--language" command option.
gdb/testsuite/ChangeLog:
* gdb.mi/mi-language.exp: New file.
gdb/doc/ChangeLog:
* gdb.texinfo (Show): Add xref anchor for "show language" command.
(Context management): Place current subsection text into its own
subsubsection. Add new subsubsection describing the "--language"
command option.
