[PATCH] D131910: [Windows] Put init_seg(compiler/lib) in llvm.global_ctors

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

Please update the AttrDocs.td <https://github.com/llvm/llvm-project/blob/main/clang/include/clang/Basic/AttrDocs.td#L109> file to document the relationship between init_seg and init_priority on Windows.

Can we increase the threshold for library so that we can insert initializers between compiler and library in the future? Maybe Microsoft will come out with some new semantic level that goes between C and L.

This is my proposed mapping:

- 101-199: A${N}, for very early things (ASan, I think)
- 200: C, compiler
- 201-399: C${N}, between compiler and library
- 400: L, library
- 401-65534: T${N}, after library, before user
- U: user, 65535
