armv7a_none_eabihf.rs

1// Generic ARMv7-A target for bare-metal code - floating point enabled (assumes
2// FPU is present and emits FPU instructions)
3//
4// This is basically the `armv7-unknown-linux-gnueabihf` target with some
5// changes (list in `armv7a_none_eabi.rs`) to bring it closer to the bare-metal
6// `thumb` & `aarch64` targets.
