The subset would disallow use of any features that rely on:
I found it manageable to write bare metal code with stock LDC and
no additional options. It doesn't require C runtime, malloc is
only 6 lines and returns ubyte[] already. LDC actually had
-noruntime option, which was only getting in the way. Some
functions from druntime are useful, e.g. _d_array_cast_len, which
allows simple casting between different types of buffers.
1. moduleinfo
I use bounds checks, and they call _d_array_bounds, which takes
ModuleInfo as a parameter. How it would work?
2. exception handling
I think asserts are sort of useful.
4. Object
I didn't try to use objects without GC, but don't see any
particular issue.
I've used such a subset before when bringing D up on a new
platform, as the new platform didn't have a working phobos.
What do you think?
Not urgent: LDC already allows me to use D without druntime,
phobos and C library.
