LDC can strip sections which DMD cannot.
Why not?
AFAIR, because of how ModuleInfo/TypeInfo is emitted which
makes linker never collect sections because they are referenced
at least from there. LDC was intentionally modified to change
code gen in that regard to make --gc-sections work - David will
surely tell more :)
It's something along those lines. What is certainly true is that
I spent quite some time trying to work around "interesting"
linker behaviour to make this work. You can find more details on
my solution at https://issues.dlang.org/show_bug.cgi?id=879.
I haven't looked at DMD's related codegen in a while, so I don't
know what exactly remains to be done there.
