[QUOTE="David Brown, post: 5151635"] Even if typeof is accepted by the compiler, the usage here is /really/ bad - it forces a volatile write to the function's parameter which will undoubtedly generate extra code, and may force a number of additional effects such as blocked optimisations, copying of register parameters into a stack frame (which may in itself force the use of a stack frame that could otherwise be omitted), etc. It also means that if you have more sophisticated optimisation at play, such as inlining, function cloning, etc., then you will make a mess with such extra volatile accesses. The simple "(void) x" should work on all compilers and produce no effect on the code. [/QUOTE]
