/*
* 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.
