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