 * Some architectures require 64-bit alignment for access to 64-bit data
 * types.  We can't just use pointers to copy 64-bit values out of our
 * interpreted register set, because gcc may assume the pointer target is
 * aligned and generate invalid code.
 *
 * There are two common approaches:
 *  (1) Use a union that defines a 32-bit pair and a 64-bit value.
 *  (2) Call memcpy().
 *
 * Depending upon what compiler you're using and what options are specified,
 * one may be faster than the other.  For example, the compiler might
 * convert a memcpy() of 8 bytes into a series of instructions and omit
 * the call.  The union version could cause some strange side-effects,
 * e.g. for a while ARM gcc thought it needed separate storage for each
 * inlined instance, and generated instructions to zero out ~700 bytes of
 * stack space at the top of the interpreter.
 *
 * The default is to use memcpy().  The current gcc for ARM seems to do
 * better with the union.

/*
 * 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.)
