| * This handler is a bit odd - it may be called via chaining or |
| * from static code and is expected to cause control to flow |
| * to the interpreter. The problem is where to find the Dalvik |
| * PC of the next instruction. When called via chaining, the dPC |
| * will be located at *rp. When called from static code, rPC is |
| * valid and rp is a real return pointer (that should be ignored). |
| * The Arm target deals with this by using the link register as |
| * a flag. If it is zero, we know we were called from static code. |
| * If non-zero, it points to the chain cell containing dPC. |
| * For x86, we'll infer the source by looking where rp points. |
| * If it points to anywhere within the code cache, we'll assume |
| * we got here via chaining. Otherwise, we'll assume rPC is valid. |
| * |
| * On entry: |
| * (TOS)<- return pointer or pointer to dPC |
