++ * With GCC 4.5 onwards we can use __builtin_unreachable to indicate to the
++ * compiler that a particular code path will never be hit. This allows it to 
be
++ * optimised out of the generated binary.
++ *
++ * Unfortunately at least GCC 4.6.3 through 7.3.0 inclusive suffer from a bug
++ * that can lead to instructions from beyond an unreachable statement being
++ * incorrectly reordered into earlier delay slots if the unreachable statement
++ * is the only content of a case in a switch statement. This can lead to
++ * seemingly random behaviour, such as invalid memory accesses from 
incorrectly
++ * reordered loads or stores. See this potential GCC fix for details:
++ *
++ *   https://gcc.gnu.org/ml/gcc-patches/2015-09/msg00360.html
++ *
++ * It is unclear whether GCC 8 onwards suffer from the same issue - nothing
++ * relevant is mentioned in GCC 8 release notes and nothing obviously relevant
++ * stands out in GCC commit logs, but these newer GCC versions generate very
++ * different code for the testcase which doesn't exhibit the bug.
++ *
++ * GCC also handles stack allocation suboptimally when calling noreturn
++ * functions or calling __builtin_unreachable():
++ *
++ *   https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82365
++ *
++ * We work around both of these issues by placing a volatile asm statement,
++ * which GCC is prevented from reordering past, prior to __builtin_unreachable
++ * calls.
++ *
++ * The .insn statement is required to ensure that any branches to the
++ * statement, which sadly must be kept due to the asm statement, are known to
++ * be branches to code and satisfy linker requirements for microMIPS kernels.
