GNU ARM vs ARM toolchain (containing ARMCC)

[bsp_user]

Hi,

Are there any recommendations for choosing one toolchain over the other for Arria V soc based baremetal projects?

Thanks

Hi bsp_user

It is a very good question.

The Arm Toolchain requires a license fee and overall a better compiler compared to the GNU ARM which is an open source compiler. Both are dedicated compiler for the Arm processor series.

You could find the difference below:

Arm Compiler (ARMCC):

• Proprietary, commercial-grade compiler developed and supported by Arm
• Generally provides better performance and more advanced optimization techniques
• Requires a license fee to use
• Supports C, C++, Fortran, and assembly language

Arm GNU GCC:

• Open-source compiler developed and maintained by the GNU Project and various contributors
• Generally not as optimized as Arm Compiler, but still provides good performance
• Free to use
• May take longer to incorporate support for new hardware features or optimizations
• Supports C and C++ (and other languages through various extensions)

Thank you for your reply.

I have some follow up questions:

1. I use the Arria V SoC with ARM compiler 5. Is it recommended for my use case to use the ARM compiler 6 (or higher)?

2. What is the latest version of ARM compiler for 32bit bare metal apps? I saw only 5 and 6 in DS-Studio. 

3. Does ARM compiler is being maintained and upgraded regularly?

Thanks

Hi bsp_user

We would recommend you use either ArmCompiler 5.16 or Linaro 7.2.0.

The Arm Compilere is maintained by ARM, and from their website they are constantly releasing new patch.

Please note that the ArriaV board is already EOL.

Hi bsp_user

Do you have any question regarding the toolchain ?

Yes, 

I just try to understand which one to choose. Are there any considerations relevant to the decision in general and bare metal projects in particular.

If there are none and both options are equal - its an answer as well.

Thank you.

Hi bsp_user

There are no significant difference between both compiler.

For general usage they are quite similar.
