 * If THREADED_INTERP is not defined, we use a classic "while true / switch"
 * interpreter.  If it is defined, then the tail end of each instruction
 * handler fetches the next instruction and jumps directly to the handler.
 * This increases the size of the "Std" interpreter by about 10%, but
 * provides a speedup of about the same magnitude.
 *
 * There's a "hybrid" approach that uses a goto table instead of a switch
 * statement, avoiding the "is the opcode in range" tests required for switch.
 * The performance is close to the threaded version, and without the 10%
 * size increase, but the benchmark results are off enough that it's not
 * worth adding as a third option.

 * The __UNION version copies data in and out of a union.  The __MEMCPY

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