3 /* The _encoded_ parameter offsets for Objective-C methods are
|
|
|
4 computed inductively as follows:
|
|
|
5 - The first paramter (self) has offset 0;
|
|
|
6 - The k-th parameter (k > 1) has offset equal to the
|
|
|
7 sum of:
|
|
|
8 - the offset of the k-1-st paramter
|
|
|
9 - the (void *)-promoted size of the k-1-st parameter.
|
|
|
10
|
|
|
11 Note that the encoded offsets need not correspond
|
|
|
12 to the actual placement of parameters (relative to 'self')
|
|
|
13 on the stack! Your target's ABI may have very different
|
|
|
14 opinions on the matter. */
