Yes, that is what the armcc linker does, the final executable has
an ordinary set of sections, no section groups, no surprises.

One thing that puzzles me though is: given two .debug_info and two
.debug_line
not in any section group, how do the armcc tools associate the right
debug_line
with each .debug_info??? Another is about .debug_abbrev being in a section
group, but applying (apparently) to ALL .debug_info.? Confusing.

The compiler involved is? not gcc (generating this object file).


Here is the? producer string from a hex dump of one .debug_info section:
Component: ARM Compiler 5.06 update 1(build 61) Tool:? armcc? [4d35ad]
