rustc_target/spec/targets/
thumbv4t_none_eabi.rs

1//! Targets the ARMv4T, with code as `t32` code by default.
2//!
3//! Primarily of use for the GBA, but usable with other devices too.
4//!
5//! Please ping @Lokathor if changes are needed.
6//!
7//! **Important:** This target profile **does not** specify a linker script. You
8//! just get the default link script when you build a binary for this target.
9//! The default link script is very likely wrong, so you should use
10//! `-Clink-arg=-Tmy_script.ld` to override that with a correct linker script.
