Possible to call inline functions in gdb and/or emit them using GCC?

One way to get the compiler to generate a callable version of an inline function is to include code that takes the address of the function. There is also an option you can give to gcc. From the gcc documentation on inline functions：

When a function is both inline and static, if all calls to the function are integrated into the caller, and the function's address is never used, then the function's own assembler code is never referenced. In this case, GCC does not actually output assembler code for the function, unless you specify the option -fkeep-inline-functions.
