 By default, GCC limits the size of functions that can be inlined.  This flag
-allows the control of this limit for functions that are explicitly marked as
-inline (i.e., marked with the inline keyword or defined within the class
-definition in c++).  @var{n} is the size of functions that can be inlined in
-number of pseudo instructions (not counting parameter handling).  The default
-value of @var{n} is 600.
-Increasing this value can result in more inlined code at
-the cost of compilation time and memory consumption.  Decreasing usually makes
-the compilation faster and less code will be inlined (which presumably
-means slower programs).  This option is particularly useful for programs that
-use inlining heavily such as those based on recursive templates with C++.

 Inlining is actually controlled by a number of parameters, which may be
 specified individually by using @option{--param @var{name}=@var{value}}.
