Update portable-atomic requirement from 0.3.15 to 1.0.0

[dependabot]

Updates the requirements on portable-atomic to permit the latest version.

Release notes

Sourced from portable-atomic's releases.

1.0.0

• Add critical-section feature to use critical-section on targets where atomic CAS is not natively available. (#51, thanks @​Dirbaio)

  This is useful to get atomic CAS when --cfg portable_atomic_unsafe_assume_single_core can't be used, such as multi-core targets, unprivileged code running under some RTOS, or environments where disabling interrupts needs extra care due to e.g. real-time requirements.

  See documentation for more.

• Remove outline-atomics feature. This was no-op since 0.3.19.

• Documentation improvements.

[1.0.0] - 2023-01-15

• Add critical-section feature to use critical-section on targets where atomic CAS is not natively available. (#51, thanks @​Dirbaio)

  This is useful to get atomic CAS when --cfg portable_atomic_unsafe_assume_single_core can't be used, such as multi-core targets, unprivileged code running under some RTOS, or environments where disabling interrupts needs extra care due to e.g. real-time requirements.

• Remove outline-atomics feature. This was no-op since 0.3.19.

• Documentation improvements.

[0.3.19] - 2022-12-25

• Add AtomicI*::{fetch_neg,neg} and AtomicF*::fetch_neg methods. (#54)

  AtomicI*::neg are equivalent to the corresponding fetch_* methods, but do not return the previous value. They are intended for optimization on platforms that have atomic instructions for the corresponding operation, such as x86's lock neg.

  Currently, optimizations by these methods (neg) are only guaranteed for x86.

• Add Atomic{I,U}*::{fetch_not,not} methods. (#54)

  Atomic{I,U}*::not are equivalent to the corresponding fetch_* methods, but do not return the previous value. They are intended for optimization on platforms that have atomic instructions for the corresponding operation, such as x86's lock not, MSP430's inv.

  Currently, optimizations by these methods (not) are only guaranteed for x86 and MSP430.

  (Note: AtomicBool already has fetch_not and not methods.)

• Enable outline-atomics for 128-bit atomics by default. (#57) See #57 for more.

• Improve support for old nightly compilers.

[0.3.18] - 2022-12-15

• Fix build error when not using portable_atomic_unsafe_assume_single_core cfg on AVR and MSP430 custom targets. (#50)

  Since 0.3.11, atomic CAS was supported without the cfg on AVR and MSP430 builtin targets, but that change was not applied to custom targets.

[0.3.17] - 2022-12-14

• Optimize x86_64 128-bit atomic load/store on AMD CPU with AVX. (#49)

• Improve support for custom targets on old rustc.

[0.3.16] - 2022-12-09

• Add Atomic{I,U}*::{add,sub,and,or,xor} and AtomicBool::{and,or,xor} methods. (#47)

  They are equivalent to the corresponding fetch_* methods, but do not return the previous value. They are intended for optimization on platforms that implement atomics using inline assembly, such as the MSP430.
