32 * Configuration defines. These affect the C implementations, i.e. the
33 * portable interpreter(s) and C stubs.
34 *
35 * Some defines are controlled by the Makefile, e.g.:
36 * WITH_PROFILER
37 * WITH_DEBUGGER
38 * WITH_INSTR_CHECKS
39 * WITH_TRACKREF_CHECKS
40 * EASY_GDB
41 * NDEBUG
42 *
43 * If THREADED_INTERP is not defined, we use a classic "while true / switch"
44 * interpreter. If it is defined, then the tail end of each instruction
45 * handler fetches the next instruction and jumps directly to the handler.
46 * This increases the size of the "Std" interpreter by about 10%, but
47 * provides a speedup of about the same magnitude.
48 *
49 * There's a "hybrid" approach that uses a goto table instead of a switch
50 * statement, avoiding the "is the opcode in range" tests required for switch.
51 * The performance is close to the threaded version, and without the 10%
52 * size increase, but the benchmark results are off enough that it's not
53 * worth adding as a third option.

1016 * It's possible to get a bad value out of a field with sub-32-bit stores
1017 * because the -quick versions always operate on 32 bits. Consider:
1018 * short foo = -1 (sets a 32-bit register to 0xffffffff)
1019 * iput-quick foo (writes all 32 bits to the field)
1020 * short bar = 1 (sets a 32-bit register to 0x00000001)
1021 * iput-short (writes the low 16 bits to the field)
1022 * iget-quick foo (reads all 32 bits from the field, yielding 0xffff0001)
1023 * This can only happen when optimized and non-optimized code has interleaved
1024 * access to the same field. This is unlikely but possible.
1025 *
1026 * The easiest way to fix this is to always read/write 32 bits at a time. On
1027 * a device with a 16-bit data bus this is sub-optimal. (The alternative
1028 * approach is to have sub-int versions of iget-quick, but now we're wasting
1029 * Dalvik instruction space and making it less likely that handler code will
1030 * already be in the CPU i-cache.)
