Permissible names are: ‘auto’, ‘vfpv2’, ‘vfpv3’, ‘vfpv3-fp16’, ‘vfpv3-d16’, ‘vfpv3-d16-fp16’, ‘vfpv3xd’, ‘vfpv3xd-fp16’, ‘neon-vfpv3’, ‘neon-fp16’, ‘vfpv4’, ‘vfpv4-d16’, ‘fpv4-sp-d16’, ‘neon-vfpv4’, ‘fpv5-d16’, ‘fpv5-sp-d16’, ‘fp-armv8’, ‘neon-fp-armv8’ and ‘crypto-neon-fp-armv8’. Note that ‘neon’ is an alias for ‘neon-vfpv3’ and ‘vfp’ is an alias for ‘vfpv2’. The setting ‘auto’ is the default and is special. It causes the compiler to select the floating-point and Advanced SIMD instructions based on the settings of -mcpu and -march. If the selected floating-point hardware includes the NEON extension (e.g. -mfpu=neon), note that floating-point operations are not generated by GCC’s auto-vectorization pass unless -funsafe-math-optimizations is also specified.

Use new features from recent Arm Architecture and from open-source projects GCC, Binutils, glibc, Newlib, and GDB.

Although cloning nonsecure entry functions is legal, as long as the clone is only used inside the secure application, the clone function itself should not be seen as a secure entry point and so it should not have the __acle_se prefix. A possible workaround for this is to add a 'noclone' attribute to functions with the 'cmse_nonsecure_entry'. This will prevent GCC from cloning such functions.

glibc, gdb, etc amplify the problem. for bare metal, it is possible to not care, if you avoid library/system calls which is where many of these named options come into play. for example if you just add two numbers the compiler should be able to generate that code and not incur platform specific calls. anyway as the world is right at the moment today the arm-none-eabi is what they configure/name is for bare metal, I am able to use the arm-linux-gnueabi variations for some things, but there are times where you start to get into trouble meaning the right stuff is not linked in or it starts to want to make system calls.

The Processor SDK Linux AM62x package uses an ARM-based tool chain. Other than using a newer version of GCC, the ARM tool chain also supports hard floating point, also known as Hard-FP. Hard-FP uses the FPU on the ARM instead of simulating it. Older tool chains including the Arago tool chain ...

September 19, 2025 - This section describes the steps to configure the command-line Arm GCC tools to build, run, and debug demo applications. This section also lists the necessary driver libraries provided in the MCUXpresso SDK.

When you invoke GCC , it normally does preprocessing, compilation, assembly and linking. The "overall options" allow you to stop this process at an intermediate stage. For example, the -c option says not to run the linker.

The Arm Developer website includes documentation, tutorials, support resources, and downloads for products and technologies.
