This patch adds *basic* support for C++ to the compile feature. It does most simple type conversions, including everything that C compile does and your basic "with-classes" type of C++. I've written a new compile-support.exp support file which adds a new test facility for automating and simplifying "compile print" vs "compile code" testing. See testsuite/lib/compile-support.exp and CompileExpression for more on that. The tests use this facility extensively. This initial support has several glaring omissions: - No template support at all I have follow-on patches for this, but they add much complexity to this "basic" support. Consequently, they will be submitted separately. - Cannot print functions The code template needs tweaking, and I simply haven't gotten to it yet. - So-called "special function" support is not included Using constructors, destructors, operators, etc will not work. I have follow-on patches for that, but they require some work because of the recent churn in symbol searching. - There are several test suite references to "compile/1234" bugs. I will file bugs and update the test suite's bug references before pushing these patches. The test suite started as a copy of the original C-language support, but I have written tests to exercise the basic functionality of the plug-in. I've added a new option for outputting debug messages for C++ type-conversion ("debug compile-cplus-types"). gdb/ChangeLog: * Makefile.in (SUBDIR_GCC_COMPILE_SRCS): Add compile-cplus-symbols.c and compile-cplus-types.c.
