2002-08-14Handle zero NEW_SIZE case.Miles Bader
2002-08-13Use `return' for null pointers, to avoid a giant block holding the restMiles Bader
of the function.
2002-08-07Per 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
2002-08-06Unify calloc (its the same thing regardless of the underlyingEric 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
2002-08-01Use 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.
2002-07-31In 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
2002-07-31Use MALLOC_HEADER_SIZE.Miles Bader
2002-07-31(MALLOC_HEADER_SIZE): New macro.Miles Bader
(MALLOC_BASE, MALLOC_ADDR): Use it.
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.
2002-07-30MALLOC_SET_SIZE now takes the user-address rather than the base-address.Miles Bader
2002-07-30Define MALLOC_SET_SIZE to take the user-address rather than the base-address.Miles Bader
2002-07-30Implement shrinking.Miles Bader
Fix bug when growing an allocation. Use new malloc header macros.
2002-07-30Use new malloc header macros.Miles Bader
2002-07-30Add macros to abstract the malloc header format a bit.Miles Bader
2002-07-25Size tweaks.Miles Bader
2002-07-25Miscellaneous tidying-up.Miles Bader
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.
2002-07-24Factor out some common code sequences into inline functions.Miles Bader
2002-07-24Misc small cleanups.Miles Bader
2002-07-24Remove, since it's entirely incorrectMiles 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
2002-07-19Rename mutex stuff to use heap-specific names.Miles Bader
Doc fix.
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!
2002-07-16We don't need the debug versionsEric Andersen
2001-12-19Update my email address. I am no longer andersen@lineo.comEric Andersen
2001-09-29Minor cleanupEric Andersen
2001-09-27Update to accomodate the header file changesEric Andersen
2001-05-12Ok, this should finish off my massive ro-organization. The sourceEric Andersen
tree is less messy now (which helps), all libraries are placed into uClibc/lib when compiling, all libraries now use a consistant mechanism for being built, all libraries use a consistant naming scheme where the lib name includes the uClibc version number, which makes ldconfig happy and willing to work with us. -Erik
2001-05-11A patch from Matthias Kilian <kili@outback.escape.de> to fix -DDEBUG_MALLOCEric Andersen
so that it works for realloc too. -Erik
2001-03-19Fix up breakage resulting from flipping the sense of some defines. Change fromEric Andersen
defining things to "0" in the disabled case to outright undefining them, lest code that does an "#ifdef FOO" get inadvertantly triggered. Remove now unneeded lines from Rules.mak which makes the command line smaller and avoids redundancy (since this stuff is now pulled in via features.h). -Erik
2001-02-21Update to "malloc" so it will work on CPUs not supporting non-aligned words.Eric Andersen
malloc still only works for little-endian CPUs... Patch by Jean-Yves Avenard
