25 | * What is the most efficient way of loading/storing an unaligned value? | ||
26 | * | ||
27 | * That is the subject of this file. Efficiency here is defined as | ||
28 | * minimum code size with minimum register usage for the common cases. | ||
29 | * It is currently not believed that long longs are common, so we | ||
30 | * trade efficiency for the chars, shorts and longs against the long | ||
31 | * longs. | ||
32 | * | ||
33 | * Current stats with gcc 2.7.2.2 for these functions: | ||
34 | * | ||
35 | * ptrsize get: code regs put: code regs | ||
36 | * 1 1 1 1 2 | ||
37 | * 2 3 2 3 2 | ||
38 | * 4 7 3 7 3 | ||
39 | * 8 20 6 16 6 | ||
40 | * | ||
41 | * gcc 2.95.1 seems to code differently: | ||
42 | * | ||
43 | * ptrsize get: code regs put: code regs | ||
44 | * 1 1 1 1 2 | ||
45 | * 2 3 2 3 2 | ||
46 | * 4 7 4 7 4 | ||
47 | * 8 19 8 15 6 | ||
48 | * | ||
49 | * which may or may not be more efficient (depending upon whether | ||
50 | * you can afford the extra registers). Hopefully the gcc 2.95 | ||
51 | * is inteligent enough to decide if it is better to use the | ||
52 | * extra register, but evidence so far seems to suggest otherwise. | ||
53 | * | ||
54 | * Unfortunately, gcc is not able to optimise the high word | ||
55 | * out of long long >> 32, or the low word from long long << 32 | ||
