@file mysql/psi/mysql_file.h
Instrumentation helpers for mysys file io.
This header file provides the necessary declarations
to use the mysys file API with the performance schema instrumentation.
In some compilers (SunStudio), 'static inline' functions, when declared
but not used, are not optimized away (because they are unused) by default,
so that including a static inline function from a header file does
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 mysys file io APIs, including mysql/psi/mysql_file.h assumes that
the dependency on my_sys already exists.

/**
@file mysql/psi/mysql_thread.h
Instrumentation helpers for mysys threads, mutexes,
read write locks and conditions.
This header file provides the necessary declarations
to use the mysys thread API with the performance schema instrumentation.
In some compilers (SunStudio), 'static inline' functions, when declared
but not used, are not optimized away (because they are unused) by default,
so that including a static inline function from a header file does
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_pthread / safemutex / etc APIs,
including mysql/psi/mysql_thread.h assumes that
the dependency on my_pthread 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
SAFE_MUTEX is defined when debug is compiled in.
This may happen both with and without instrumentation.
Dimension 3: Platform
Mutexes are implemented with one of:
- the pthread library
- fast mutexes
- window apis
This is implemented by various macro definitions in my_pthread.h
This causes complexity with '#ifdef'-ery that can't be avoided.

Consider the following code:
static inline void foo() { bar(); }
when foo() is never called.
With gcc, foo() is a local static function, so the dependencies
are optimized away at compile time, and there is no dependency on bar().
With other compilers (HP, Sun Studio), the function foo() implementation
is compiled, and bar() needs to be present to link.
Due to the existing header dependencies in MySQL code, this header file
is sometime used when it is not needed, which in turn cause link failures
on some platforms.
The proper fix would be to cut these extra dependencies in the calling code.
DISABLE_MYSQL_THREAD_H is a work around to limit dependencies.
