2002-09-09(realloc): Record the correct size in the malloc header in the caseMiles Bader
where we extended the existing allocation, and got back more than we asked for from the heap.
2002-08-19(realloc): Follow new arg conventions of MALLOC_SET_SIZE.Miles Bader
2002-08-14Handle zero NEW_SIZE case.Miles Bader
2002-08-01Use MALLOC_REALLOC_MIN_FREE_SIZE.Miles Bader
2002-07-31In the allocate-and-copy case, don't include the malloc header in ourMiles Bader
size calculations.
2002-07-31Update debugging printfs.Miles Bader
2002-07-31Account for MALLOC_HEADER_SIZE when calculating new size.Miles Bader
2002-07-30Make sure NEW_SIZE is a multiple of HEAP_GRANULARITY.Miles Bader
Calculate amount freed when shrinking correctly.
2002-07-30Update the size of grown/shrunk allocations.Miles Bader
MALLOC_SET_SIZE now takes the user-address rather than the base-address.
2002-07-30Implement shrinking.Miles Bader
Fix bug when growing an allocation. Use new malloc header macros.
2002-07-25Redo the locking, so that it may actually work. Now locking is done atMiles Bader
the malloc/free level, not within the heap abstraction, and there's a separate lock to control sbrk access. Also, get rid of the separate `unmap_free_area' function in free.c, and just put the code in the `free' function directly, which saves a bunch of space (even compared to using an inline function) for some reason.
2002-07-24Misc small cleanups.Miles Bader
2002-07-23* Automatically try to unmap heap free-areas when they get very big.Miles Bader
* Instead of using mmap/munmap directly for large allocations, just use the heap for everything (this is reasonable now that heap memory can be unmapped). * Use sbrk instead of mmap/munmap on systems with an MMU.
2002-07-19Doc fix.Miles Bader
2002-07-18Miles Bader implemented a new mmap based malloc which is muchEric Andersen
smarter than the old "malloc-simple", and actually works, unlike the old "malloc". So kill the old "malloc-simple" and the old "malloc" and replace them with Miles' new malloc implementation. Update Config files to match. Thanks Miles!
