commit 801120c1f402f9b0f72b5a231bf9e1cf82614cac Author: Corinna Vinschen <[email protected]> Date: Fri Aug 27 14:26:42 2021 +0200 Cygwin: loader script: add DWARF 5 sections Modern gcc's generate additional DWARF 5 debug sections, which were still missing in our Cygwin loader script. With ld from binutils 2.37, this results in diagnostic output when linking the Cygwin DLL... ld: cygwin0.dll:/4: section below image base ld: cygwin0.dll:/20: section below image base ld: cygwin0.dll:/36: section below image base ...and the section addresses given to these sections (.debug_loclists, .debug_rnglists, debug_line_str) will be wrong. Fix this by adding the missing DWARF 5 sections to our linker script template cygwin.sc.in. Add a comment in terms of the deprecated DWARF 4 section .debug_types.
