No. Those tests require that there is more than one translation unit. With
"include" one has effectively one one TU.

Well, that's essentially what is currently (with the patch), except that one
runs into the "-o" issue.
I think it should be also solvable with the current dg-additional-sources -
either relying on having the ".s" in the current working directory (i.e.
getting rid of the "-o".) -- Or by compiling separately for the
dg-additional-sources (for "dg-do compile"). Probably, the former is not an
option.
Currently, it is handled as:
proc gfortran_target_compile { source dest type options } {
...
set options [dg-additional-files-options $options $source]
return [target_compile $source $dest $type $options]
}
The "dg-additional-files-options" adds the additional sources to $options.
Maybe, an option would be to do
if { $type == "compile" } {
set result [target_compile $source $dest $type $options]
foreach srcfile $additional_sources {
lappend result [target_compile $srcfile $dest $type $options]
}
return $result
}
Or something like that. (It probably needs some refinement as
"dg-additional-files-options" also supports downloading etc. I am also not sure
whether "foreach" properly splits the files in '{ dg-additional-sources
"class_4b.f03 class_4c.f03" }', though it might do so.)
