  • Always provide atomic CAS for MSP430 and AVR. (#31)

    This previously required unsafe cfg portable_atomic_unsafe_assume_single_core, but since all MSP430 and AVR are single-core, we can safely provide atomic CAS based on disabling interrupts.

  • Support fence and compiler_fence on MSP430. (On MSP430, the standard library's fences are currently unavailable due to LLVM errors.)

  • Update safety requirements for unsafe cfg portable_atomic_unsafe_assume_single_core to mention use of privileged instructions to disable interrupts.

  • Atomic operations based on disabling interrupts on single-core systems are now considered lock-free.

    The previous behavior was inconsistent because we consider the pre-v6 ARM Linux's atomic operations provided in a similar way by the Linux kernel to be lock-free.

  • Respect -Zallow-features.
