build(deps): update cortex-m requirement from 0.5.0 to 0.7.1 #23

Closed dependabot-preview[bot] closed 3 years ago

dependabot-preview[bot] commented 3 years ago

Updates the requirements on cortex-m to permit the latest version.

Release notes

Sourced from cortex-m's releases.

v0.7.1

Added

  • New assembly methods asm::semihosting_syscall, asm::bootstrap, and asm::bootload.

Deprecated

  • msp::write has been deprecated in favor of asm::bootstrap. It was not possible to use msp::write without causing Undefined Behavior, so all existing users are encouraged to migrate.

Fixed

  • Fixed a bug in asm::delay which could lead to incorrect codegen and infinite loops.
  • Improved timing guarantees of asm::delay on multiple-issue CPU cores.
  • Additional compiler fences added to inline assembly where necessary.
  • Fixed DWARF debug information in pre-built assembly binaries.

[v0.7.1] - 2021-01-25

Added

  • New assembly methods asm::semihosting_syscall, asm::bootstrap, and asm::bootload.

Deprecated

  • msp::write has been deprecated in favor of asm::bootstrap. It was not possible to use msp::write without causing Undefined Behavior, so all existing users are encouraged to migrate.

  • Fixed DWARF debug information in pre-built assembly binaries.

[v0.7.0] - 2020-11-09

Added

  • New InterruptNumber trait is now required on interrupt arguments to the various NVIC functions, replacing the previous use of Nr from bare-metal. For backwards compatibility, InterruptNumber is implemented for types which are Nr + Copy, but this will be removed in a future version.
  • Associated const PTR is introduced to Core Peripherals to eventually replace the existing ptr() API.
  • A delay driver based on SysTick.
  • You can now use LTO to inline assembly calls, even on stable Rust. See the asm/lib.rs documentation for more details.
  • Initial ARMv8-M MPU support
  • ICTR and ACTLR registers added
  • Support for the Security Attribution Unit on ARMv8-M

Changed

  • Previously, asm calls without the inline-asm feature enabled used pre-built objects which were built by a GCC compiler, while inline-asm enabled the use of llvm_asm! calls. The asm system has been replaced with a new technique which generates Rust static libs for stable calling, and uses the new asm! macro with inline-asm. See the asm/lib.rs documentation for more details.
  • Cache enabling now uses an assembly sequence to ensure correctness.
  • ptr() methods are now const.
