+ create unwanted dependencies, causing unresolved symbols at link time. + Other compilers, like gcc, optimize these dependencies by default. + + Since the instrumented APIs declared here are wrapper on top + of my_thread / safemutex / etc APIs, + including mysql/psi/mysql_thread.h assumes that + the dependency on my_thread and safemutex already exists. +*/ +/* + Note: there are several orthogonal dimensions here. + + Dimension 1: Instrumentation + HAVE_PSI_INTERFACE is defined when the instrumentation is compiled in. + This may happen both in debug or production builds. + + Dimension 2: Debug
