* void crosscall2(void (*fn)(void*, int32, uintptr), void*, int32, uintptr)
* Save registers and call fn with two arguments.
TEXT crosscall2(SB),NOSPLIT,$-4
* We still need to save all callee save register as before, and then
* push 3 args for fn (R5, R6, R7).
* Also note that at procedure entry in gc world, 4(R29) will be the
* first arg.
// Space for 9 caller-saved GPR + LR + 6 caller-saved FPR.
// O32 ABI allows us to smash 16 bytes argument area of caller frame.
