Critical - core_util_atomic_decr/incr are undefined

[0xc0170]

Undefined functions core_util_atomic_decr/incr. There's no function with a declaration to match: core_util_atomic_decr((uintptr_t)valuePtr, (uintptr_t)delta) . I would assume that missing functions should be implemented, and can't be on top of current functions because they return a value, and these functions return void pointer. The API documentation should state that (be more specific), not The new decremented value. as the rest of API.

I'm facing this issue as well on top of today's mbed/master ... it seems to happen "only" on cortex-M0/M0+ targets.
Has this pass through CI compilation ?

Pr up: #2131. It was a last minute change and went unnoticed since GCC only emits a warning.

can't be on top of current functions because they return a value, and these functions return void pointer

That is my bad, I was missing the warning emitted for differing return values. I'll fix this in a separate pr once #2131 is merged.

Due to IAR errors I went ahead and fixed the casting issue @0xc0170 noticed on #2131. Let me know if there's still an issue.

Now that #2131 is merged, is this still an issue?
