| 44 | * handler fetches the next instruction and jumps directly to the handler. |
| 45 | * This increases the size of the "Std" interpreter by about 10%, but |
| 46 | * provides a speedup of about the same magnitude. |
| 47 | * |
| 48 | * There's a "hybrid" approach that uses a goto table instead of a switch |
| 49 | * statement, avoiding the "is the opcode in range" tests required for switch. |
| 50 | * The performance is close to the threaded version, and without the 10% |
| 51 | * size increase, but the benchmark results are off enough that it's not |
| 52 | * worth adding as a third option. |

| 1022 | * It's possible to get a bad value out of a field with sub-32-bit stores |
| 1023 | * because the -quick versions always operate on 32 bits. Consider: |
| 1024 | * short foo = -1 (sets a 32-bit register to 0xffffffff) |
| 1025 | * iput-quick foo (writes all 32 bits to the field) |
| 1026 | * short bar = 1 (sets a 32-bit register to 0x00000001) |
| 1027 | * iput-short (writes the low 16 bits to the field) |
| 1028 | * iget-quick foo (reads all 32 bits from the field, yielding 0xffff0001) |
| 1029 | * This can only happen when optimized and non-optimized code has interleaved |
| 1030 | * access to the same field. This is unlikely but possible. |
| 1031 | * |
| 1032 | * The easiest way to fix this is to always read/write 32 bits at a time. On |
| 1033 | * a device with a 16-bit data bus this is sub-optimal. (The alternative |
| 1034 | * approach is to have sub-int versions of iget-quick, but now we're wasting |
| 1035 | * Dalvik instruction space and making it less likely that handler code will |
