I think clang support is definitely a requirement going forward. IMO It
would be nice to support IAR and Keil as options, although it would mean
maintaining multiple linker scripts and a portability layer that
abstracted:
- Packed structs
- Inline assembler
- Memory sections
Not impossible, but hard to do readably.
What are people’s thoughts? I know Keil and IAR have reasonable usage
now, but are they important compilers to invest time into now to
support, or has their time passed?

Hi, I just wanted to jump in here and suggest that -std=c11 is a
better
choice than -std=gnuXX. If you allow GNU specific extensions then you
might have issues using other compilers - certainly I would be
surprised
to see the project to rule out clang support in the future. I would
suggest c11 over c99 as it offers things like atomics which might be
useful.
I was under the impression that Mynewt already uses some gnu
extensions,
though I could be wrong about that. Regarding clang- it also supports
the gnuXX "standards". It would be nice to support other compilers as
well, but I think that would be quite an uphill battle, and these
days,
I wonder how many people would want to use a toolchain other than gcc
or
clang for Mynewt.
