2011-04-11Fix malloc alignmentBernd Schmidt
In commit 3e0a1f388, Richard tried to fix malloc alignments by using alignof (double __attribute_aligned__(sizeof (size_t))). This doesn't work, since attribute_aligned overrides the alignment rather than providing a minimum. On C6X, malloc returns four-byte aligned values rather than the necessary eight-byte alignment. It's simpler to use a comparison and pick the bigger of the two values, so that's what I've done. Signed-off-by: Bernd Schmidt <bernds@codesourcery.com>

2009-12-19malloc: fix race condition and other bugs in the no-mmu mallocFreeman Wang
Fixes multiple race conditions on mmb list. This was done by making the mmb_heap_lock into a recursive lock and making the regular heap_lock extend to cover the mmb heap handling. Also move the new_mmb allocation up to before the mmb list is iterated through to find the insertion point. When the mmb_heap also runs out and needs to be extended when the regular heap is just extended, the mmb list could be messed up.

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>

2009-01-21*: remove __UCLIBC_CURLOCALE_DATA, __UCLIBC_CURLOCALE_DATA.xDenis Vlasenko
is always equivalent to __UCLIBC_CURLOCALE->x. remove typedef __uclibc_locale_t, it used only in a few places, it is lees confusing to use struct __uclibc_locale_struct everywhere. xlocale.h: hide __global_locale back under _LIBC, bug 53 is wrong in claiming it should be exported. Also hide under _LIBC: extern __locale_t __curlocale_var; extern __locale_t __curlocale(void); extern __locale_t __curlocale_set(__locale_t newloc); # define __UCLIBC_CURLOCALE # define __XL_NPP(N) # define __LOCALE_PARAM # define __LOCALE_ARG # define __LOCALE_PTR
