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.
