GNU ARM vs ARM toolchain (containing ARMCC)

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

    Hi bsp_user


    There are no significant difference between both compiler.

    For general usage they are quite similar.

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)



Regards

Jingyang, Teh

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
