2003-04-02(free_to_heap): Unlock the heap before returning in theMiles Bader
__UCLIBC_UCLINUX_BROKEN_MUNMAP__ case. Fix from YYang1@Winbond.com.tw.
2002-11-21Improve malloc debugging support.Miles Bader
2002-10-15Fix locking to not deadlock when __UCLIBC_UCLINUX_BROKEN_MUNMAP__ is defined.Miles Bader
2002-10-09* Add support for uClinux's broken munmap, contingent onMiles 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.
2002-09-04(free):Miles Bader
Update debug statement. Update to use __heap_delete and __heap_is_empty.
2002-08-30Use `likely' & `unlikely' instead of the `__malloc_'-prefixed versions.Miles Bader
2002-08-14Use __malloc_unlikely instead of `likely'.Miles Bader
2002-08-13Use `return' for null pointers, to avoid a giant block holding the restMiles Bader
of the function.

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.
2002-07-24Misc 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.

2002-07-18Miles 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!
