In the mean time, we got basic debugging working. There's one problem
left I'm not sure how to solve though. In the DWARF compilation unit
header, you have to record the start and the end address of the code
in that compilation unit (= object file). We currently do this by
inserting a ".text" section at the start of the object file with a
start label, and one at the end of the object file with an end label.
On Win32 however, we don't put any code in a plain ".text" section. We
put all code is sections called like ".text.n_p$test_proc" and
".text.n__main". The linker script afterwards groups all .text*
sections, but it puts the plain ".text" sections first. As a result,
all these start and end labels end up at exactly the same location: at
the very beginning of the code section of the entire application,
rather than at the individual start and end addresses of the code from
the individual object files.
I don't immediately see how to fix this. Maybe be we can put those
labels at the start and end of the al_procedures assembler lists for
Windows, but I don't know whether we never put .text* sections in any
other assembler lists.
