arm none-eabi to LLVM upgrade

Hi Experts,

I am using arm none-eabi version 4.5.1 for code compilation.

Is it recommended to upgraded to Clang + LLVM compiler ?

How far it is matured for bare metal code (cortex M and R profiles) ?

Which one is good for baremetal C++ code development ? GCC or LLVM + Clang ?

  • Clang current doesn't have a mature mechanism to support multilib, namely pre-building and choosing the right static libraries for different targets.

    Quality and performance wise we don't have enough info to claim which one is better than another. It will be helpful for users to share their cases showing correctness or performance difference.
