/* TEMPLATE_FUNCTION_TABLE()
|

|
|
|

|
|
(Note added to platform.h so platforms that correctly support templated
|
||
|
|
functions can handle portions as templated functions rather than wrapped
|
||
|
|
functions)
|
||
|
|
|
||
|
|
Helps automate the process of creating an array of function
|
||
|
|
templates that are all specialized by a single integer.
|
||
|
|
This sort of thing is often useful in optimization work.
|
||
|
|
|
||
|
|
For example, using TEMPLATE_FUNCTION_TABLE, this:
|
||
|
|
|
||
|
|
TEMPLATE_FUNCTION_TABLE(int, Function, ( int blah, int blah ), 10)
|
||
|
|
{
|
||
|
|
return argument * argument;
|
||
|
|
}
|
||
|
|
|
||
|
|
is equivilent to the following:
|
||
|
|
|
||
|
|
(NOTE: the function has to be wrapped in a class due to code
|
||
|
|
generation bugs involved with directly specializing a function
|
||
|
|
based on a constant.)
