在davik vm / mterp / out / InterpC-portable.cpp代码中,当解释invokeMethod时,我发现它只能处理count小于或等于5的情况:
switch (count) {
case 5:
outs[4] = GET_REGISTER(vsrc1 & 0x0f);
case 4:
outs[3] = GET_REGISTER(vdst >> 12);
case 3:
outs[2] = GET_REGISTER((vdst & 0x0f00) >> 8);
case 2:
outs[1] = GET_REGISTER((vdst & 0x00f0) >> 4);
case 1:
outs[0] = GET_REGISTER(vdst & 0x0f);
default:
;
}
那么当参数大小超过5时呢?
答案 0 :(得分:1)
对不起,我想念一些事情,我提到的参议员是非远程通话的情况,我错过了一个范围通话:
*/
if (methodCallRange) {
// could use memcpy or a "Duff's device"; most functions have
// so few args it won't matter much
assert(vsrc1 <= curMethod->outsSize);
assert(vsrc1 == methodToCall->insSize);
outs = OUTS_FROM_FP(fp, vsrc1);
for (i = 0; i < vsrc1; i++)
outs[i] = GET_REGISTER(vdst+i);
....
所以它在这里处理!
