-/*
- * What is the most efficient way of loading/storing an unaligned value?
- *
- * That is the subject of this file.  Efficiency here is defined as
- * minimum code size with minimum register usage for the common cases.
- * It is currently not believed that long longs are common, so we
- * trade efficiency for the chars, shorts and longs against the long
- * longs.
- *
- * Current stats with gcc 2.7.2.2 for these functions:
- *
- *      ptrsize get:    code    regs    put:    code    regs
- *      1               1       1               1       2
- *      2               3       2               3       2
- *      4               7       3               7       3
- *      8               20      6               16      6
- *
- * gcc 2.95.1 seems to code differently:
- *
- *      ptrsize get:    code    regs    put:    code    regs
- *      1               1       1               1       2
- *      2               3       2               3       2
- *      4               7       4               7       4
- *      8               19      8               15      6
- *
- * which may or may not be more efficient (depending upon whether
- * you can afford the extra registers).  Hopefully the gcc 2.95
- * is inteligent enough to decide if it is better to use the
- * extra register, but evidence so far seems to suggest otherwise.
- *
- * Unfortunately, gcc is not able to optimise the high word
- * out of long long >> 32, or the low word from long long << 32

- * What is the most efficient way of loading/storing an unaligned value?
- *
- * That is the subject of this file.  Efficiency here is defined as
- * minimum code size with minimum register usage for the common cases.
- * It is currently not believed that long longs are common, so we
- * trade efficiency for the chars, shorts and longs against the long
- * longs.
- *
- * Current stats with gcc 2.7.2.2 for these functions:
- *
- *      ptrsize get:    code    regs    put:    code    regs
- *      1               1       1               1       2
- *      2               3       2               3       2
- *      4               7       3               7       3
- *      8               20      6               16      6
- *
- * gcc 2.95.1 seems to code differently:
- *
- *      ptrsize get:    code    regs    put:    code    regs
- *      1               1       1               1       2
- *      2               3       2               3       2
- *      4               7       4               7       4
- *      8               19      8               15      6
- *
- * which may or may not be more efficient (depending upon whether
- * you can afford the extra registers).  Hopefully the gcc 2.95
- * is inteligent enough to decide if it is better to use the
- * extra register, but evidence so far seems to suggest otherwise.
- *
- * Unfortunately, gcc is not able to optimise the high word
- * out of long long >> 32, or the low word from long long << 32
