*	namespace fixes for sys/mman.h	Rich Felker	2011-04-20	1	-0/+1
*	fix rare but nasty under-allocation bug in malloc with large requests•••the bug appeared only with requests roughly 2sizeof(size_t) to 4sizeof(size_t) bytes smaller than a multiple of the page size, and only for requests large enough to be serviced by mmap instead of the normal heap. it was only ever observed on 64-bit machines but presumably could also affect 32-bit (albeit with a smaller window of opportunity).

*	avoid over-allocation of brk on first malloc•••if init_malloc returns positive (successful first init), malloc will retry getting a chunk from the free bins rather than expanding the heap again. also pass init_malloc a hint for the size of the initial allocation.	Rich Felker	2011-04-01	1	-4/+4
*	rename __simple_malloc.c to lite_malloc.c - yes this affects behavior!•••why does this affect behavior? well, the linker seems to traverse archive files starting from its current position when resolving symbols. since calloc.c comes alphabetically (and thus in sequence in the archive file) between __simple_malloc.c and malloc.c, attempts to resolve the "malloc" symbol for use by calloc.c were pulling in the full malloc.c implementation rather than the __simple_malloc.c implementation. as of now, lite_malloc.c and malloc.c are adjacent in the archive and in the correct order, so malloc.c should never be used to resolve "malloc" unless it's already needed to resolve another symbol ("free" or "realloc").

*	very cheap double-free checks in malloc	Rich Felker	2011-03-23	1	-0/+4
*	global cleanup to use the new syscall interface	Rich Felker	2011-03-20	1	-1/+1
*	make malloc(0) return unique pointers rather than NULL•••this change is made with some reluctance, but i think it's for the best. correct programs must handle either behavior, so there is little advantage to having malloc(0) return NULL. and i managed to actually make the malloc code slightly smaller with this change.

*	fix simple_malloc malloc(0) behavior not to return non-unique pointers	Rich Felker	2011-02-20	1	-0/+1
*	fix simple_malloc size restrictions•••do not allow allocations that overflow ptrdiff_t; fix some overflow checks that were not quite right but didn't matter due to address layout implementation.	Rich Felker	2011-02-20	1	-5/+6
*	initial check-in, version 0.5.0	Rich Felker	2011-02-12	7	-0/+671
