| | | | | | memcpy() or memmove(). | |||||
| * | Preserve %o5 around Lbcopy_doubles; prevents the return value from memcpy() | miod | 2013-06-15 | 1 | -4/+5 | |
| | | | | | | and memmove() to be incorrect for copies of 32 bytes or more, when the source and destination addresses are nicely aligned. | |||||

| * | take libc bcopy, gut the #ifdefs for other modes, and place it here. | deraadt | 2013-06-13 | 1 | -0/+116 | |

| * | Optimize memcpy(9) by always doing a forward copy; it should never be used | kettenis | 2013-06-11 | 1 | -9/+9 | |
| | | | | | | | | | for overlapping copies. Attempt to be instruction cache friendly by turning things around and make memcpy(9) use the forward copy branch of memmove(9), and implement bcopy(9) by swapping its arguments and dropping into memmove(9). Same change as the one just made to for hppa. | |||||
