Compiler Issues in apple Silicon Processors

[Vedaant-Rajoo]

While building the compiler on my system, I came across this error while running CheckedC code. While reading through the documentation for the special clang compiler, I found out that ARM processors are indeed supported. So I don't understand what went wrong.

I'm guessing this problem is not specific to 3C or Checked C and also occurs in the upstream Clang revision on which they are based (currently 8e464dd, a.k.a. llvmorg-13-init^); I'm not aware of any change specific to 3C or Checked C that could cause this kind of problem.

Can you please test revision 8e464dd using the same build procedure you used for 3C and see if the same problem occurs? If it does, it almost certainly won't be a priority for us to make a one-off fix to the 3C or Checked C code. If the problem has been fixed in a newer version of upstream Clang, hopefully 3C and Checked C will eventually be upgraded and inherit the fix. The other thing you could try is tinkering with the build flags. If you find that the 3C build instructions are not valid for Apple silicon and you can propose a fix, we'll be happy to mention it in the documentation.
