Hello,

Following the Tech Forum yesterday I am repeating the questions asked at the time.

Please share your opinions

• Do we need C++ support on S side?
• CLANG/LLVM toolchain name
• toolchain_CLANG.cmake vs toolchain_LLVM.cmake
• Can we drop the support of –march –mtune options in favor of –mcpu only?
• Can we limit supported toolchains to the earliest version with m55 support?

In other words: is there anyone who must use toolchains earlier than in the table?

Toolchain	Cortex-M55 support since	Release Date
ArmClang	V6.14	March 2020
GNU Arm Embedded Toolchain	V10.	December 2020
LLVM Embedded Toolchain for Arm	V11.0.0	September 2020
IAR Embedded Workbench	V8.50	November 2020

Thanks,

Anton
