David,

Constructor order is determined by the build tool through evaluation of each of the library instance dependencies as declared in the [LibraryClasses] section of the INF.  This is a recursive algorithm to collect all the library instances because a module uses libs and each lib can use additional libs.

This process is described in the EDK II Build Specification in Section 8.2.5 Post processing.

https://edk2-docs.gitbooks.io/edk-ii-build-specification/content/8_pre-build_autogen_stage/82_auto-generation_process.html#82-auto-generation-process

If you want a different order, then likely one or more of the lib instances being linked to a module does not have correct information about its lib dependencies in the [LibraryClasses] section of the INF.  If the dependencies are specified correctly, then the order generated by the build tool should be a valid order based on dependencies.  There are some cases where there could be ties, such that the order could be different and still correct, but there is no way to influence the order between ties.

Mike

Subject: [edk2] Constructor Order

So I'm back from years ago trying to work out the constructor order.
It doesn't seem any change I make causes autogen.c to change the order to what I want to happen.  At least if someone could indicate which file I need to use to check the order, that would help.  I presume it's the .inf file of items being built in the [libraryclasses] section ?

I don't think [Packages] should matter?

TIA!!
