Description
In my local linux machine, for
export module a;
When I generate the code, I can see:
define void @_ZGIW1a() #0 section ".text.startup" {
entry:
ret void
}
this is used for initializing entities for the module unit. Itanium C++ ABI asks us to generate this even if we don't need to initialize any thing.
But if I turned MSVC ABI, I can say nothing for the initializer. We need input from MSVC, either formal docs or developers, how should we do here. And if we missed anything, we need to implement the module initializer for Windows ABI.
Estimated difficulty: medium
