   4 Subject: [PATCH] Move cfi_startproc after CNAME(label)
   5
   6 This is a fix for https://github.com/libffi/libffi/issues/852: error: invalid CFI advance_loc expression on apple targets.
   7
   8 The CFI for darwin arm64 was broken because the CNAME macro was being used after the
   9 cfi_startproc macro.
