| * | The BSD qsort() performs tail recursion elimination on the second | millert | 2017-05-17 | 1 | -10/+25 | |
| | | | | | | | | | side of the array being partitioned to save on stack space. Greater savings can be gained by choosing recursion for the smaller side of the partition and eliminating recursion for the larger side. This also results in a small but measurable performance gain.

| * | For small allocations (chunk) freezero only validates the given | otto | 2017-04-22 | 1 | -5/+10 | |
| | | | | | | | | | size if canaries are enabled. In that case we have the exact requested size of the allocation. But we can at least check the given size against the chunk size if C is not enabled. Plus add some braces so my brain doesn't have to scan for dangling else problems when I see this code. | |||||

| * | 1. When shrinking a chunk allocation, compare the size of the current | otto | 2017-01-21 | 1 | -46/+87 | |
| | | | | | | | | | | | allocation to the size of the new allocation (instead of the requested size). 2. Previously realloc takes the easy way and always reallocates if C is active. This commit fixes by carefully updating the recorded requested size in all cases, and writing the canary bytes in the proper location after reallocating. 3. Introduce defines to test if MALLOC_MOVE should be done and to compute the new value. | |||||
| * | Remove unnecessary casts of 'a' to char * since 'a' is already char *. | millert | 2017-01-04 | 1 | -10/+10 | |

| * | Pages in the malloc cache are either reused quickly or unmapped | otto | 2016-10-28 | 1 | -14/+1 | |
| | | | | | | | quickly. In both cases it does not make sense to set hints on them. So remove that option, which is just a remainder of old times when malloc used to hold on to pages. ok stefan@ | |||||
