Make these testcases work when compiled as C++ programs. These testcases use the alias attribute, which requires passing in the target function's mangled name in C++. To avoid having to figure out how the functions are mangled, explicitly specify a linkage name. This is preferred over 'extern "C"' because that doesn't work with static functions. gdb/testsuite/ChangeLog: * gdb.base/prologue.c [__cplusplus] (marker): Explicitly specify linkage name. * gdb.base/prologue.exp: Use print /d. * gdb.base/symbol-alias.exp: Handle C++ output. * gdb.base/symbol-alias2.c: Handle C++ output. [__cplusplus] (func): Explicitly specify linkage name.
