Hi,
I just installed gcc-arm-11.2-2022.02-darwin-x86_64-arm-none-eabi.pkg on a Mac with Apple Silicon.Trying to compile anything, always results in this error: internal compiler error: Illegal instruction: 4I don't have any of these issues with the previous release of the toolchain (gcc-arm-none-eabi-10.3-2021.10-mac.pkg).I also tried version 11.2-2022.02 on an Intel based Mac, and there are no compiler errors, as can be seen below.
