I am currently investigating
http://d.puremagic.com/issues/show_bug.cgi?id=9571 and after
brief exploration of symbols emitted to object file as well as
code that emits them I can't rid of an idea that I am missing
something about module system.
Why does dmd emits horde of symbols from imported modules into
object files, most of whose are not actually used in this one?
No "-inline" used and I kind of expected to see there only
directly called function and symbols from their signatures.
What does actually happen here?
Okay, after some digging on the topic I am quite sure that DMD
does add instantiated template symbols from imported modules to
root module symbol list (template.c:5023). It does not care if
root module was actually one to start template instantiation
chain (and thus uses this symbol) and just bloats the symbol
table.
Repeating initial question - was there rationale for this other
than being reluctant to store additional context information
about initial template chain instantiation scope?
I'd like to make a pull request for this and make one step closer
to making separate compilation reality but don't want to waste
time on dmd source code (argh) without real need, thus
preliminary question.
