# Run-time support for Arm AArch32 Processors
This library implements a simple Arm vector table, suitable for getting into a
Rust application running in System Mode. It also provides a reference start up
method. Some Arm AArch32 based systems will require chip specific start-up
code, so the start-up method can be overridden. It should be suitable for:
* Legacy Arm Processors, like the ARM7TDMI and ARM926
* Armv7-R Processors, like the Arm Cortex-R5
* Armv8-R AArch32 Processors, like the Arm Cortex-R52
* Armv7-A Processors, like the Arm Cortex-A5
* Armv8-A AArch32 Processors, like the Arm Cortex-A53 running in 32-bit mode
It does not support any M-Profile Processors (like the Arm Cortex-M3) as they
have a fundamentally different interrupt vector table.
It also does not support processors running in AArch64 mode - A64 machine code
uses different instructions for reading/writing system registers.
## Minimum Supported Rust Version (MSRV)
This crate is guaranteed to compile on stable Rust 1.83.0 and up, as recorded
by the `package.rust-version` property in `Cargo.toml`.
Increasing the MSRV is not considered a breaking change and may occur in a
minor version release (e.g. from `0.3.0` to `0.3.1`, because this is still a
`0.x` release).
