41 * If THREADED_INTERP is not defined, we use a classic "while true / switch"

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

1039 * It's possible to get a bad value out of a field with sub-32-bit stores
1040 * because the -quick versions always operate on 32 bits. Consider:
1041 * short foo = -1 (sets a 32-bit register to 0xffffffff)
1042 * iput-quick foo (writes all 32 bits to the field)
1043 * short bar = 1 (sets a 32-bit register to 0x00000001)
1044 * iput-short (writes the low 16 bits to the field)
1045 * iget-quick foo (reads all 32 bits from the field, yielding 0xffff0001)
1046 * This can only happen when optimized and non-optimized code has interleaved
1047 * access to the same field. This is unlikely but possible.
1048 *
1049 * The easiest way to fix this is to always read/write 32 bits at a time. On
1050 * a device with a 16-bit data bus this is sub-optimal. (The alternative
1051 * approach is to have sub-int versions of iget-quick, but now we're wasting
1052 * Dalvik instruction space and making it less likely that handler code will
1053 * already be in the CPU i-cache.)
