thumbv8m.base-none-eabi

Tier: 2

Bare-metal target for CPUs in the Baseline Armv8-M architecture family, supporting a subset of the T32 ISA.

Processors in this family include the:

• Arm Cortex-M23

See arm-none-eabi for information applicable to all arm-none-eabi targets.

This target uses the soft-float ABI: functions which take f32 or f64 as arguments will have those values packed into integer registers. This is the only option because there is no FPU support in Armv8-M Baseline.
