- armv7a-none-eabihf
|

|
||||
Bare-metal target for 32-bit ARM CPUs.
|
||||
|
||||
If a target has a `*hf` variant, that variant uses the hardware floating-point
|
||||
ABI and enables some minimum set of floating-point features based on the FPU(s)
|
||||
available in that processor family.
|
||||
|
||||
## Requirements
|
||||
|
||||
These targets are cross-compiled and use static linking.
|
||||
|
||||
By default, the `lld` linker included with Rust will be used; however, you may
|
||||
want to use the GNU linker instead. This can be obtained for Windows/Mac/Linux
|
||||
from the [Arm Developer Website][arm-gnu-toolchain], or possibly from your OS's
|
||||
package manager. To use it, add the following to your `.cargo/config.toml`:
|
||||
|
||||
```toml
|
||||
[target.<your-target>]
|
||||
linker = "arm-none-eabi-ld"
|
||||
```
|
||||
|
||||
The GNU linker can also be used by specifying `arm-none-eabi-gcc` as the
|
||||
linker. This is needed when using GCC's link time optimization.
|
||||
|
||||
[arm-gnu-toolchain]: https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain
|
||||
|
||||
These targets don't provide a linker script, so you'll need to bring your own
|
||||
according to the specific device you are using. Pass
|
||||
`-Clink-arg=-Tyour_script.ld` as a rustc argument to make the linker use
|
||||
`your_script.ld` during linking.
|
||||
|
||||
Targets named `thumb*` instead of `arm*`
|
||||
generate Thumb-mode code by default. M-profile processors (`thumbv*m*-*`
|
||||
targets) only support Thumb-mode code.
|
||||
For the `arm*` targets, Thumb-mode code generation can be enabled by using
|
||||
`-C target-feature=+thumb-mode`. Using the unstable
|
||||
`#![feature(arm_target_feature)]`, the attribute
|
||||
`#[target_feature(enable = "thumb-mode")]` can be applied to individual
|
||||
`unsafe` functions to cause those functions to be compiled to Thumb-mode code.
|
||||
|
||||
## Building Rust Programs
|
||||
|
||||
For the Tier 3 targets in this family, rust does not ship pre-compiled
|
||||
artifacts.
|
||||
|
||||
Just use the `build-std` nightly cargo feature to build the `core` library. You
|
||||
can pass this as a command line argument to cargo, or your `.cargo/config.toml`
|
||||
file might include the following lines:
|
||||
|
||||
```toml
|
||||
[unstable]
|
||||
build-std = ["core"]
|
||||
```
|
||||
|
||||
Most of `core` should work as expected, with the following notes:
|
||||
* If the target is not `*hf`, then floating-point operations are emulated in
|
||||
software.
|
||||
* Integer division is also emulated in software on some targets, depending on
|
||||
the CPU.
|
||||
* Architectures prior to ARMv7 don't have atomic instructions.
|
||||
|
||||
`alloc` is also supported, as long as you provide your own global allocator.
|
||||
|
||||
Rust programs are output as ELF files.
|
||||
|
||||
## Testing
|
||||
|
||||
This is a cross-compiled target that you will need to emulate during testing.
|
||||
|
||||
The exact emulator that you'll need depends on the specific device you want to
|
||||
run your code on.
|
||||
|
||||
## Cross-compilation toolchains and C code
|
||||
|
||||
The target supports C code compiled with the `arm-none-eabi` target triple and
|
||||
a suitable `-march` or `-mcpu` flag.
|
||||
|
||||
`gcc` or `clang` can be used, but note that `gcc` uses `-fshort-enums` by
|
||||
default for `arm-none*` targets, while `clang` does not. `rustc` matches the
|
||||
`gcc` behavior, i.e., the size of a `#[repr(C)] enum` in Rust can be as little
|
||||
as 1 byte, rather than 4, as they are on `arm-linux` targets.

|

Most of `core` should work as expected, with the following notes:

|
||||
software.
|
||||
* integer division is also emulated in software.
|
||||
* the target is old enough that it doesn't have atomic instructions.
|
||||
|
||||
Rust programs are output as ELF files.
|
||||
|
||||
For running on hardware, you'll generally need to extract the "raw" program code
|
||||
out of the ELF and into a file of its own. The `objcopy` program provided as

part of the GNU Binutils can do this:

Because this is a device-agnostic target, and the exact emulator that you'll

need depends on the specific device you want to run your code on.

For example, when programming for the DS, you can use one of the several available DS emulators, such as [melonDS](https://melonds.kuribo64.net/).

# `arm(eb)?v7r-none-eabi(hf)?`
|
||||
|
||||
**Tier: 2**
|
||||
|
||||
Bare-metal target for CPUs in the ARMv7-R architecture family, supporting
|
||||
dual ARM/Thumb mode, with ARM mode as the default.
|
||||
|
||||
Processors in this family include the [Arm Cortex-R4, 5, 7, and 8][cortex-r].
|
||||
|
||||
The `eb` versions of this target generate code for big-endian processors.
|
||||
|
||||
See [`arm-none-eabi`](arm-none-eabi.md) for information applicable to all
|
||||
`arm-none-eabi` targets.

## Requirements
|
||||
|
||||
When using the big-endian version of this target, note that some variants of
|
||||
the Cortex-R have both big-endian instructions and data. This configuration is
|
||||
known as BE-32, while data-only big-endianness is known as BE-8. To build
|
||||
programs for BE-32 processors, the GNU linker must be used with the `-mbe32`
|
||||
option. See [ARM Cortex-R Series Programmer's Guide: Endianness][endianness]
|
||||
for more details about different endian modes.
|
||||
|
||||
When using the hardfloat targets, the minimum floating-point features assumed
|
||||
are those of the `vfpv3-d16`, which includes single- and double-precision, with
|
||||
16 double-precision registers. This floating-point unit appears in Cortex-R4F
|
||||
and Cortex-R5F processors. See [VFP in the Cortex-R processors][vfp]
|
||||
for more details on the possible FPU variants.
|
||||
|
||||
If your processor supports a different set of floating-point features than the
|
||||
default expectations of `vfpv3-d16`, then these should also be enabled or
|
||||
disabled as needed with `-C target-feature=(+/-)`.

|
||||
## Cross-compilation toolchains and C code
|
||||
|
||||
This target supports C code compiled with the `arm-none-eabi` target triple and
|
||||
`-march=armv7-r` or a suitable `-mcpu` flag.
