48 * Some architectures require 64-bit alignment for access to 64-bit data
49 * types. We can't just use pointers to copy 64-bit values out of our
50 * interpreted register set, because gcc may assume the pointer target is
51 * aligned and generate invalid code.
52 *
53 * There are two common approaches:
54 * (1) Use a union that defines a 32-bit pair and a 64-bit value.
55 * (2) Call memcpy().
56 *
57 * Depending upon what compiler you're using and what options are specified,
58 * one may be faster than the other. For example, the compiler might
59 * convert a memcpy() of 8 bytes into a series of instructions and omit
60 * the call. The union version could cause some strange side-effects,
61 * e.g. for a while ARM gcc thought it needed separate storage for each
62 * inlined instance, and generated instructions to zero out ~700 bytes of
63 * stack space at the top of the interpreter.
64 *
65 * The default is to use memcpy(). The current gcc for ARM seems to do
66 * better with the union.

1012 * short bar = 1 (sets a 32-bit register to 0x00000001)
1013 * iput-short (writes the low 16 bits to the field)
1014 * iget-quick foo (reads all 32 bits from the field, yielding 0xffff0001)
1015 * This can only happen when optimized and non-optimized code has interleaved
1016 * access to the same field. This is unlikely but possible.
1017 *
1018 * The easiest way to fix this is to always read/write 32 bits at a time. On
1019 * a device with a 16-bit data bus this is sub-optimal. (The alternative
1020 * approach is to have sub-int versions of iget-quick, but now we're wasting
1021 * Dalvik instruction space and making it less likely that handler code will
1022 * already be in the CPU i-cache.)
