Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2013-04-04add UCLIBC_SUSV2_LEGACY to hide vallocBernhard Reutner-Fischer
valloc was marked as LEGACY in SUSv2, removed from SUSv3 and later. TODO: Remove this (point people to memalign and it's successors?). Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2013-02-05mman: rename MAP_UNINITIALIZE to MAP_UNINITIALIZEDBernhard Reutner-Fischer
The name was changed to include a trailing 'D' when it went into the kernel. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

move __libc_free_aligned prototype up to a common place. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2010-07-27malloc-simple: Make calloc() return zeroed memorySteven J. Magnani
The 0.9.31 release included a change to malloc-simple to request uninitialized memory from noMMU kernels. Unfortunately, the corresponding calloc() code assumed that memory returned by malloc() was already zeroed, which leads to all kinds of nastiness. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2009-11-23nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger
Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use it to get real uninitialized memory on no-mmu systems. This avoids a lot of normally useless overhead involved in zeroing out all of the memory (sometimes multiple times). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2003-12-30Rework malloc. The new default implementation is based on dlmalloc from DougEric Andersen
Lea. It is about 2x faster than the old malloc-930716, and behave itself much better -- it will properly release memory back to the system, and it uses a combination of brk() for small allocations and mmap() for larger allocations. -Erik
2003-12-30Update and restore malloc-simple. Slow as molasses, but triviallyEric Andersen
simple and releases memory immediately when asked to do so. -Erik
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!
