thumbv7m-none-eabi
Tier: 2
Bare-metal target for CPUs in the Armv7-M architecture family, supporting a subset of the T32 ISA.
Processors in this family include the:
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 Armv7-M.
