2006-03-05 Roland McGrath <roland@redhat.com>
* malloc/malloc.c (MALLOC_ALIGNMENT): Set to __alignof__ (long double)
if long double is more aligned than 2 * SIZE_SZ.
(misaligned_chunk): Define.
(public_rEALLOc, _int_free, _int_realloc): Use it.
* malloc/malloc.c (MALLOC_ALIGNMENT): Revert to (2 * SIZE_SZ) value.
The correct value differs only on powerpc32, and for now changing it
there is causing more trouble than it's worth.
* malloc/arena.c: Add compile-time sanity check on padding calculation.
2006-03-05 Jakub Jelinek <jakub@redhat.com>
* malloc/arena.c (heap_info): Adjust the padding size if
MALLOC_ALIGNMENT > 2 * SIZE_SZ.
2006-03-05 Roland McGrath <roland@frob.com>
* sysdeps/posix/sysconf.c (__sysconf): Use #if _POSIX_FOO > 0
rather than #ifdef _POSIX_FOO for options. We should return -1
at runtime for an option defined to 0 at compile time.
* sysdeps/mach/hurd/bits/posix_opt.h: Define many missing options,
many to -1 or 0.
2006-03-05 Roland McGrath <roland@redhat.com>
* sysdeps/unix/sysv/linux/sysconf.c (__sysconf)
[__NR_clock_getres || HP_TIMING_AVAIL]: Handle _SC_CPUTIME,
_SC_THREAD_CPUTIME.
