[PATCH] D149340: [AMDGPU] Place global constructors in .init_array and .fini_array

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

I know little about GPU. The generic code emittings constructors to assembly is `AsmPrinter::emitSpecialLLVMGlobal` and `AsmPrinter::emitXXStructorList`. It will use `.init_array`.

The priority works this way. Note that in the absence of a `.N` suffix, `.init_array` has the highest priority. https://maskray.me/blog/2021-11-07-init-ctors-init-array

  a.o:(.init_array.1) b.o:(.init_array.1)
  a.o:(.init_array.2) b.o:(.init_array.2)
  ...
  a.o:(.init_array.65533) b.o:(.init_array.65533)
  a.o:(.init_array.65534) b.o:(.init_array.65534)
  a.o:(.init_array) b.o:(.init_array)
