/* Reserved bytes to the native thread stack boundary, throw native

 *
 * WASM_STACK_GUARD_SIZE needs to be large enough for:
 *
 * - native functions
 *
 *   w/o hw bound check, the overhead (aot_call_function etc) + the native
 *   function itself. as of writing this, the former is about 1000 bytes
 *   on macOS amd64.
 *
 *   with hw bound check, theoretically, only needs to cover the logic to
 *   set up the jmp_buf stack.
 *
 * - aot runtime functions
 *   eg. aot_enlarge_memory.
 *
 * - w/o hw bound check, the interpreter loop
 *
 *   the stack consumption heavily depends on compiler settings,
 *   especially for huge functions like the classic interpreter's
 *   wasm_interp_call_func_bytecode:
 *
 *     200 bytes (release build, macOS/amd64)
 *     2600 bytes (debug build, macOS/amd64)
 *
 * - platform-provided functions (eg. libc)
 *
 *   the following are examples of the stack consumptions observed for
 *   host APIs.
 *
 *   snprintf: (used by eg. wasm_runtime_set_exception)
 *   - about 1600 bytes on macOS/amd64
 *   - about 2000 bytes on Ubuntu amd64 20.04
 *
 *   gethostbyname:
 *   - 3KB-6KB on macOS/amd64
 *   - 10KB on Ubuntu amd64 20.04
 *
 *   getaddrinfo:
 *   - 4KB-17KB on macOS/amd64
 *   - 12KB on Ubuntu amd64 20.04
 *   - 0.3-1.5KB on NuttX/esp32s3
 *
 * - stack check wrapper functions generated by the aot compiler
 *   (--stack-bounds-checks=1)
 *
 *   wamrc issues a warning
 *   "precheck functions themselves consume relatively large amount of stack"
 *   when it detects wrapper functions requiring more than 1KB.
 *
 * - the ABI-defined red zone. eg. 128 bytes for SYSV x86-64 ABI.
 *   cf. https://en.wikipedia.org/wiki/Red_zone_(computing)
 *
 * Note: on platforms with lazy function binding, don't forget to consider
 * the symbol resolution overhead on the first call. For example,
 * on Ubuntu amd64 20.04, it seems to consume about 1500 bytes.
 * For some reasons, macOS amd64 12.7.4 seems to resolve symbols eagerly.
 * (Observed with a binary with traditional non-chained fixups.)
 * The latest macOS seems to apply chained fixups in kernel on page-in time.
 * (thus it wouldn't consume userland stack.)
