What does this flag do? I didn't see any documentation for it in the
commit log or sources... If I do a --savec output, I still get 53 files
including a bunch of the internal ones (ChapelBase, ChapelLocale, etc.)
and the resulting binary seg faults for a code that shouldn't require the
internal modules in any deep way:
var x = 1;
extern proc printf(x...);
printf("%ld\n", x);
What I'm hoping for in this thread is a mode in which I can compile the
program above, only get one major .c file corresponding to a Chapel module
in the output directory (with probably a few other boilerplate files like
chpl__header.h, _config.c), and a working executable. If
--ignore-internal-modules is a path to that, I'm open to it, but I'm not
able to connect what I'm seeing to what I want.

I'm not imagining that changes to modules/ would also need to be made to
modules-minimal/ unless it was a new requirement for the compiler to
fulfill (e.g., the compiler looks for certain symbols in certain cases).
This doesn't happen very often, so I'd expect that most changes to
modules/ wouldn't need to be reflected to modules-minimal/ (and those that
do might point to weaknesses in the proposed approach).
Thanks for any additional information,
