| * Some architectures require 64-bit alignment for access to 64-bit data |

| * 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 |

| * 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 |
