* 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.)
