1. Elemental, Pure, and Recursive Procedures

DWARF 4 defines attributes for these Fortran procedure specifiers: DW_AT_elemental, DW_AT_pure, DW_AT_recursive, resp. LLVM has a way of informing the DWARF generator of simple boolean attributes in the metadata via the flags parameter. We have added these new values to the existing collection of flags.

!60 = !DISubprogram(…, flags: DIFlagElemental)
!61 = !DISubprogram(…, flags: DIFlagPure)
!62 = !DISubprogram(…, flags: DIFlagRecursive)
