* * Add support for uClinux's broken munmap, contingent onMiles Bader2002-10-091-18/+68
| | | | | | | | | __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.
* Update debugging hooks.Miles Bader2002-09-061-0/+4

| | | | | | | | | 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.
* Misc small cleanups.Miles Bader2002-07-241-1/+2
|
* * Automatically try to unmap heap free-areas when they get very big.Miles Bader2002-07-231-60/+50
| | | | | | | | * 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.
* Doc fix.Miles Bader2002-07-191-1/+1

* Miles Bader implemented a new mmap based malloc which is muchEric Andersen2002-07-181-867/+94
| | | | | | | 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!

* Fix up breakage resulting from flipping the sense of some defines. Change fromEric Andersen2001-03-191-9/+10
| | | | | | | | 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
* Update to "malloc" so it will work on CPUs not supporting non-aligned words.Eric Andersen2001-02-211-7/+35
| | | | malloc still only works for little-endian CPUs... Patch by Jean-Yves Avenard

* Patch from James Graves <jgraves@deltamobile.com> to better handle m68k.Eric Andersen2001-01-121-2/+13
| | | | | | Also fixes 2 very important malloc bugs! Anyone using malloc (esp mmu-less) should update and recompile. -Erik
* Manuel Novoa III modified malloc.c and avlmacro.h to reduce code size byEric Andersen2001-01-121-534/+642

* A bunch of updates, part from Manuel Novoa III (such as more long longEric Andersen2001-01-011-2/+2
