* This has the same form as other method calls, but we ignore
* the 5th argument (vA). This is chiefly because the first four
* arguments to a function on ARM are in registers.
*
* We only set the arguments that are actually used, leaving
* the rest uninitialized. We're assuming that, if the method
* needs them, they'll be specified in the call.
*
* However, this annoys gcc when optimizations are enabled,
* causing a "may be used uninitialized" warning. Quieting
* the warnings incurs a slight penalty (5%: 373ns vs. 393ns
* on empty method). Note that valgrind is perfectly happy
* either way as the uninitialiezd values are never actually
* used.
