Age	Commit message (Collapse)	Author
2002-10-09	* Add support for uClinux's broken munmap, contingent on	Miles Bader
	__UCLIBC_UCLINUX_BROKEN_MUNMAP__ (which is currently not defined anywhere). This makes other cases a tiny bit less efficient too. * Move the malloc lock into the heap structure (locking is still done at the malloc level though, not by the heap functions). * Initialize the malloc heap to contain a tiny initial static free-area so that programs that only do a very little allocation won't ever call mmap.
2002-09-13	(__heap_check_failure): New function.	Miles Bader
	(__heap_check): Add more checks. Use `__heap_check_failure'.
2002-09-09	(realloc): Record the correct size in the malloc header in the case	Miles Bader
	where we extended the existing allocation, and got back more than we asked for from the heap.
2002-09-06	Initial checkin.	Miles Bader

2002-09-06	Update debugging hooks.	Miles Bader

2002-09-04	(free):	Miles Bader
	Update debug statement. Update to use __heap_delete and __heap_is_empty.
2002-09-04	(__heap_delete): Renamed from `__heap_unlink_free_area'.	Miles Bader
	(__heap_free_area_alloc): Use __heap_delete. (__heap_is_empty): New macro.
2002-08-30	Doc fix.	Miles Bader

2002-08-30	(__heap_free): Tighten up the inner loop, and make the code more readable.	Miles Bader

2002-08-30	Use `likely' & `unlikely' instead of the `__malloc_'-prefixed versions.	Miles Bader

2002-08-30	(likely, unlikely): New macros.	Miles Bader

2002-08-30	(likely, unlikely): New macros.	Miles Bader
	(__malloc_likely, __malloc_unlikely): Macros removed.
2002-08-19	(CSRC): Make contents source files, not object files.	Miles Bader

2002-08-19	(CSRC): Add `memalign.c'.	Miles Bader

2002-08-19	Initial checkin.	Miles Bader

2002-08-19	(realloc): Follow new arg conventions of MALLOC_SET_SIZE.	Miles Bader

2002-08-19	(malloc): Use MALLOC_SETUP.	Miles Bader

2002-08-19	(MALLOC_SETUP): New macro.	Miles Bader
	(MALLOC_SET_SIZE): Take the base-address of the block, not the user-address. (MALLOC_ADDR): Macro removed.
2002-08-14	Use __malloc_unlikely instead of `likely'.	Miles Bader

2002-08-14	Add flow-control hints with __malloc_likely and __malloc_unlikely.	Miles Bader

2002-08-14	(__malloc_likely, __malloc_unlikely): New macros.	Miles Bader

2002-08-14	Handle zero NEW_SIZE case.	Miles Bader

2002-08-13	Use `return' for null pointers, to avoid a giant block holding the rest	Miles Bader
	of the function.
2002-08-07	Per suggestion from Miles Bader, move calloc.c to libc/stdlib.	Eric Andersen
	Also, Manuel notices that I forgot to check for when nmemb=0, which would result in a segfault, so fix that case as well. -Erik
2002-08-06	Unify calloc (its the same thing regardless of the underlying	Eric Andersen
	malloc implementation). Fix problem reported to bugtraq about problems with integer overflow that can occur during the computation of the memory region size by calloc (and similar functions) which could result in a subsequent buffer overflow. -Erik
2002-08-01	Use MALLOC_REALLOC_MIN_FREE_SIZE.	Miles Bader

2002-08-01	(MALLOC_REALLOC_MIN_FREE_SIZE): New macro.	Miles Bader
	Enable debugging if MALLOC_DEBUGGING is defined.
2002-08-01	(HEAP_MIN_SIZE): New macro.	Miles Bader
	(HEAP_MIN_FREE_AREA_SIZE): Increase size. Enable debugging if HEAP_DEBUGGING is defined.
2002-07-31	In the allocate-and-copy case, don't include the malloc header in our	Miles Bader
	size calculations.
2002-07-31	Update debugging printfs.	Miles Bader

2002-07-31	Account for MALLOC_HEADER_SIZE when calculating new size.	Miles Bader

2002-07-31	Use MALLOC_HEADER_SIZE.	Miles Bader

2002-07-31	(MALLOC_HEADER_SIZE): New macro.	Miles Bader
	(MALLOC_BASE, MALLOC_ADDR): Use it.
2002-07-30	Make sure NEW_SIZE is a multiple of HEAP_GRANULARITY.	Miles Bader
	Calculate amount freed when shrinking correctly.
2002-07-30	Update the size of grown/shrunk allocations.	Miles Bader
	MALLOC_SET_SIZE now takes the user-address rather than the base-address.
2002-07-30	MALLOC_SET_SIZE now takes the user-address rather than the base-address.	Miles Bader

2002-07-30	Define MALLOC_SET_SIZE to take the user-address rather than the base-address.	Miles Bader

2002-07-30	Implement shrinking.	Miles Bader
	Fix bug when growing an allocation. Use new malloc header macros.
2002-07-30	Use new malloc header macros.	Miles Bader

2002-07-30	Add macros to abstract the malloc header format a bit.	Miles Bader

2002-07-25	Size tweaks.	Miles Bader

2002-07-25	Miscellaneous tidying-up.	Miles Bader

2002-07-25	Redo the locking, so that it may actually work. Now locking is done at	Miles 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.
2002-07-24	Factor out some common code sequences into inline functions.	Miles Bader

2002-07-24	Misc small cleanups.	Miles Bader

2002-07-24	Remove, since it's entirely incorrect	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.
2002-07-19	Doc fix.	Miles Bader

2002-07-19	Rename mutex stuff to use heap-specific names.	Miles Bader
	Doc fix.
2002-07-18	Miles Bader implemented a new mmap based malloc which is much	Eric 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!
