#DllLoad directive to preload DLLs Topic is solved

[just me]

DllCall()
Performance
[AHK_L 31+]: If DllCall's first parameter is a literal string such as "MulDiv" and the DLL containing the function is ordinarily loaded before the script starts, the string is automatically resolved to a function address. This built-in optimization is more effective than the example shown above.

This optimization seems to work only for DLLs loaded by AHK but not for DLLs loaded per DllCall("LoadLibrary", ...) within the script. A #DllLoad directive evaluated before the expression parser is called should solve this problem. Also, missing DLLs could be detected at load-time.

I was going through my notes and found a reference to this topic. You may like to know that Helgef implements this (under the name #LoadLibrary) in PR #136.
