Do we have any official benchmark comparing ARM and GNU compilers?

Senthil Kumar Rajagopal

Hello,

Few of my customers started to have concerns on the quality of the GNU`s GCC compilers.

Before I talk about the performance gain in using the ARM compiler to my clients, I would like to know is there any

official compiler benchmark comparing the ARM compiler and GNU?


I am only hearing that usage of NEON instruction through ARM compilers yields better performance compared to

doing the same thing using GNU`s GCC compiler?


Is there any document comparing different aspects of both of these compilers?


Regards,

    ARM doesn't publish benchmark comparisons between compilers. There are far too many variables (compilers, compiler versions, benchmarks, command line options, etc) to do this in a meaningful way. Instead, we encourage users to run their own tests and we are happy to provide evaluation licenses to enable this.

    Generally speaking, the ARM Compiler excels at ...

    • Compact code size
    • Library size and performance
    • NEON autovectorization performance
    • Performance / code size tradeoff, i.e. very good performance without compromising code size

    These are of course generalisations and we encourage users to run their own tests.
