adding hints for the compiler for optimization.
In case your custom build complains about "const", just remove the keyword. based on e82f38e277, but going further :-)
* "const" class functions : function does not modify any class attributes ( --> "this" becomes const)
* __attribute__((pure)) : function return value depends only on the parameters and/or global variables. The function does not modify any global or static variables.
* __attribute__((const)) : function only examines arguments (no globals), and has no effects except the return value. This slightly more strict than "pure"
* hot: tells the compiler "this functions is called very often"
* cold: the opposite of hot

* Where has everything gone?
|
|
*
|
|
* In April 2020, the project's structure underwent a major change.
|
|
* Global variables are now found in file "wled.h"
|
|
* Global function declarations are found in "fcn_declare.h"
|
|
*
|
|
* Usermod compatibility: Existing wled06_usermod.ino mods should continue to work. Delete usermod.cpp.
|
|
* New usermods should use usermod.cpp instead.
