2002-07-31Use MALLOC_HEADER_SIZE.Miles Bader
2002-07-30MALLOC_SET_SIZE now takes the user-address rather than the base-address.Miles Bader
2002-07-30Use new malloc header macros.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.
2002-07-24Misc 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!
2001-09-29Minor cleanupEric Andersen
2001-09-27Update to accomodate the header file changesEric Andersen
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
2001-01-15Reduce dependancies -- don't use sysconf() internal to libc.Eric Andersen
2001-01-12"I will always compile before I commit."Eric Andersen
"I will always compile before I commit." "I will always compile before I commit." -Erik
2001-01-12Patch from James Graves <jgraves@deltamobile.com> to better handle m68k.Eric Andersen
Also fixes 2 very important malloc bugs! Anyone using malloc (esp mmu-less) should update and recompile. -Erik
2001-01-12Manuel Novoa III modified malloc.c and avlmacro.h to reduce code size byEric Andersen
using functions instead on Inlining (size vas speed tradeoff). I ran the results through indent. Looking pretty good IMHO.
2001-01-01A bunch of updates, part from Manuel Novoa III (such as more long longEric Andersen
support), and other updates by me (better cross platform, cross-compiler, etc, support. Now compiles with 2.0.x kernels for armnommu.
2000-11-04More cleanups. Fix things so tinylogin compiles.Eric Andersen
Fix a bug in getdelim -- patch from David Whedon <dwhedon@gordian.com>.
2000-10-12Screwed up non-mmu support. #define was backwards.Eric Andersen

2000-10-11Finish reorganizing things. At least I think I've finished.Eric Andersen
