# 82 "s-atocou.adb" 1
isn't a .file assignment though.
As I said earlier, if we don't want to revert the r11-3693 change and be able
to specify -gdwarf-5 etc. to gas even when compiling files that contain
explicit .debug_info from the compiler, then we need gas to act as if all that
option affects is the version of the .debug_line emitted for explicit
.file*/.loc* directives if present and nothing else (whenever the assembly
contains manual
.file*/.loc* directives or .debug_{info,line,...} sections). So, basically,
gas can start preparing for generation of its own .debug_* sections but should
roll all that back when it sees .file/.loc directives or user
.debug_{info,line} sections (perhaps some others).
Or, the other option is not to pass -gdwarf-5 to gas, but pass
-gdwarf-line-version=5 or whatever other new option, which would only change
the decision on if gas emits .debug_line section because of .file*/.loc*
directives (and .debug_line is not present), what version of that to use.
