@section Is Fast Code or Small Code preferred?

@cindex Optimization
|
||||
|
||||
If an application uses many floating point function it is often the case
|
||||
that the costs for the function calls itseld are not neglectable.
|
||||
Modern processor implementation often can execute the operation itself
|
||||
very fast but the call means a disturbance of the control flow.
|
||||
|
||||
For this reason the GNU C Library provides optimizations for many of the
|
||||
frequently used math functions. When the GNU CC is used and the user
|
||||
activates the optimizer several new inline functions and macros get
|
||||
defined. These new functions and macros have the same names as the
|
||||
library function and so get used instead of the later. In case of
|
||||
inline functions the compiler will decide whether it is reasonable to
|
||||
use the inline function and this decision is usually correct.
|
||||
|
||||
For the generated code this means that no calls to the library functions
|
||||
are necessary. This increases the speed significantly. But the
|
||||
drawback is that the code size increases and this increase is not always
|
||||
neglectable.
|
||||
|
||||
In cases where the inline functions and macros are not wanted the symbol
|
||||
@code{__NO_MATH_INLINES} should be defined before any system header is
|
||||
included. This will make sure only library functions are used. Of
|
||||
course it can be determined for each single file in the project whether
|
||||
giving this option is preferred or not.

A completely broken interface was designed by the POSIX.1 committee to

support reproducible random numbers in multi-threaded programs.

@deftypefun int rand_r (unsigned int *@var{seed})
|
||||
This function returns a random number in the range 0 to @code{RAND_MAX}
|
||||
just as @code{rand} does. But this function does not keep an internal
|
||||
state for the RNG. Instead the @code{unsigned int} variable pointed to
|
||||
by the argument @var{seed} is the only state. Before the value is
|
||||
returned the state will be updated so that the next call will return a
|
||||
new number.
|
||||
|
||||
I.e., the state of the RNG can only have as much bits as the type
|
||||
@code{unsigned int} has. This is far too few to provide a good RNG.
|
||||
This interface is broken by design.
|
||||
|
||||
If the program requires reproducible random numbers in multi-threaded
|
||||
programs the reentrant SVID functions are probably a better choice. But
|
||||
these functions are GNU extensions and therefore @code{rand_r}, as being
|
||||
standardized in POSIX.1, should always be kept as a default method.
