Currently all mockable functions are annotated with the 'noinline' attribute. This is insufficient to guarantee that a function can be reliably mocked with an LD_PRELOAD. The C language spec allows the compiler to assume there is only a single implementation of each function. It can thus do things like propagating constant return values into the caller at compile time, or creating multiple specialized copies of the function body each optimized for a different caller. To prevent these optimizations we must also set the 'noclone' and 'weak' attributes. This fixes the test suite when libvirt.so is built with CLang with optimization enabled. Signed-off-by: Daniel P.
