* When making a (pure) debug build, the compiler will by default disable
|
|
* inlining of functions. This has a detremental effect on the performance of
|
|
* debug builds, especially when more and more trivial (wrapper) functions get
|
|
* added to the code base.
|
|
* Take for example the savegame called "Wentbourne", when running this game
|
|
* for 100 ticks with the null video driver a number of fairly trivial
|
|
* functions show up on top. The most common one is the implicit conversion
|
|
* operator of TileIndex to unsigned int, which takes up over 5% of the total
|
|
* run time and functionally does absolutely nothing. The remaining functions
|
|
* for the top 5 are GB, GetTileType, Map::Size and IsTileType to a total of
|
|
* about 12.5% of the game's total run time.
|
|
* It is possible to still force inlining in the most commonly used compilers,
|
|
* but that is at the cost of some problems with debugging due to the forced
|
|
* inlining. However, the performance benefit can be enormous; when forcing
|
|
* inlining for the previously mentioned top 5, the debug build ran about 15%
|
|
* quicker.
|
|
* The following debug_inline annotation may be added to functions comply
|
|
* with the following preconditions:
|
|
* 1: the function takes more than 0.5% of a profiled debug runtime
|
|
* 2: the function does not modify the game state
|
|
* 3: the function does not contain selection or iteration statements,
|
|
* i.e. no if, switch, for, do, while, etcetera.
|
|
* 4: the function is one line of code, excluding assertions.
|
|
* 5: the function is defined in a header file.
|
|
* The debug_inline annotation must be placed in front of the function, i.e.
|
|
* before the optional static or constexpr modifier.
