is using of arm toolchain from developer.arm.com feasible?
After installing zephyr-sdk-0.11.2, I checked arm g++ version:
arm-zephyr-eabi-g++ (crosstool-NG 188.8.131.52-3f461da-dirty) 9.2.0
Why "dirty"? Should I worry?
How feasible is it to use the a toolchain direct from developer.arm.com (1) when buliding zephyr projects?
More general, why vendors tend to supply their own toolchain builds? (My target is STM32. ST goes way "further" and supplies with their STM32CubeIDE old GNU Tools for STM32 7-2018-q2-update.20190328-1800 7.3.1 20180622 (release) [ARM/embedded-7-branch revision 261907])
