[rustc.git] / src / librustc_target / spec / armv7a_none_eabihf.rs

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