arm-none-eabi - Toolchain for ARM Embedded Processors Cortex-R/M

Gërmia is collection of GNU C/C++ cross compiler tools for ARM Embedded Processors Cortex-R/M.
It is used for embedded applications without an operating system. This GNU Cross Toolchain
is not for systems with Linux or uClinux kernel. Package is composed of gcc-4.6.2,
binutils-2.22, newlib-1.19.0 and gdb-7.3.

Supported processors are Cortex-R and Cortex-M. Compiler is invoked with
following options:
Cortex-M0: -mthumb -mcpu=cortex-m0
Cortex-M1: -mthumb -march=armv6-m

Cortex-M3: -mthumb -mcpu=cortex-m3
(or) -mthumb -march=armv7-m

Cortex-M4 (no fp): -mthumb -mcpu=cortex-m4
(or) -mthumb -march=armv7e-m

Cortex-M4(soft fp) : -mthumb -mcpu=cortex-m4 -mfloat-abi=softfp -mfpu=fpv4-sp-d16
(or) -mthumb -march=armv7e-m -mfloat-abi=softfp -mfpu=fpv4-sp-d16

Cortex-M4(hard fp) : -mthumb -mcpu=cortex-m4 -mfloat-abi=hard -mfpu=fpv4-sp-d16
(or) -mthumb -march=armv7e-m -mfloat-abi=hard -mfpu=fpv4-sp-d16

Cortex-R4 & Cortex-R5 (no fp): -march=armv7-r
(or) -mthumb -march=armv7-r

Cortex-R4 &Cortex-R5(soft fp): -mthumb -march=armv7-r -mfloat-abi=softfp -mfpu=vfpv3-d16
(or) -march=armv7-r -mfloat-abi=softfp -mfpu=vfpv3-d16

Cortex-R4 &Cortex-R5(hard fp): -mthumb -march=armv7-r -mfloat-abi=hard -mfpu=vfpv3-d16
