2015-02-17Use alignment macros, pagesize and powerof2.Carlos O'Donell
We are replacing all of the bespoke alignment code with ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN. This cleans up malloc/malloc.c, malloc/arena.c, and elf/dl-reloc.c. It also makes all the code consistently use pagesize, and powerof2 as required. Code size is reduced with the removal of precomputed pagemask, and use of pagesize instead. No measurable difference in performance. No regressions on x86_64.

2013-03-08Remove __malloc_ptr_t.Joseph Myers
2013-01-17Add HAVE_MREMAP for mremap usagePino Toscano
Introduce (only on Linux) and use a HAVE_MREMAP symbol to advertize mremap availability. Move the malloc-sysdep.h include from arena.c to malloc.c, since what is provided by malloc-sysdep.h is needed earlier in malloc.c, before the inclusion of arena.c.

2012-10-04Name space hygeine for madvise.Roland McGrath
2012-09-25Shrink heap on linux when overcommit_memory == 2Siddhesh Poyarekar
Using madvise with MADV_DONTNEED to release memory back to the kernel is not sufficient to change the commit charge accounted against the process on Linux. It is OK however, when overcommit is enabled or is heuristic. However, when overcommit is restricted to a percentage of memory setting the contents of /proc/sys/vm/overcommit_memory as 2, it makes a difference since memory requests will fail. Hence, we do what we do with secure exec binaries, which is to call mmap on the region to be dropped with MAP_FIXED. This internally unmaps the pages in question and reduces the amount of memory accounted against the process.
