aarch64_unknown_none_softfloat.rs

1// Generic AArch64 target for bare-metal code - Floating point disabled
2//
3// Can be used in conjunction with the `target-feature` and
4// `target-cpu` compiler flags to opt-in more hardware-specific
5// features.
6//
7// For example, `-C target-cpu=cortex-a53`.
