don't extra notify ModulesDidLoad() from LoadModuleAtAddress()

Authored by llunak on Apr 5 2022, 6:52 AM.



Places calling LoadModuleAddress() already call ModulesDidLoad() after a loop calling LoadModuleAtAddress(), so it's not necessary to call it from there, and the batched ModulesDidLoad() may be more efficient than this place calling it one after one.

This also makes the ModuleLoadedNotifys test pass on Linux now that the duplicates no longer bring down the average of modules notified per call.

This change is a prerequisite for parallelizing PreloadSymbols() in D122975.

Note that this patch could have been shorter if I simply changed LoadModuleAtAddress() to always pass false for notify (all callers currently call ModulesDidLoad() afterwards) and added a note to LoadModuleAtAddress() docs about it, but I don't know if that's a good design choice.

That would definitely be better.

Changed to always disable notify and added a comment about that to LoadModuleAtAddress().
