commit 403cb6b138c38faf72f7abc034db3505b9bdb82f
Author: Joel Brobecker <>
Date:   Mon Nov 11 09:21:44 2013 +0400

    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*)"
            * 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.mi/mi-language.exp: New file.
            * 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.
