Added assembler optimized INT64 byteswapping and here is the latest results:
(Using Visual C++ 6.0 Standard Edition on AMD Athlon XP 2200+ @ 1800 MHz)
NOTE: USING x86 inline assembly swap functions!
testing B_HOST_TO_LENDIAN_* ...
testing B_LENDIAN_TO_HOST_* ...
testing B_HOST_TO_BENDIAN_* ...
testing B_BENDIAN_TO_HOST_* ...
Correctness test complete.
Now doing speed testing....
B_SWAP_INT16 exercise took 343ms to complete.
B_SWAP_INT32 exercise took 312ms to complete.
B_SWAP_INT64 exercise took 359ms to complete.
B_SWAP_FLOAT exercise took 812ms to complete.
B_SWAP_DOUBLE exercise took 1562ms to complete.
