* nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger2009-11-231-0/+2
| | | | | | | | | 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>
* clean up O_CLOEXEC handlingMike Frysinger2009-10-071-2/+0
| | | | | | | Drop the "#ifndef O_CLOEXEC" cruft, enable O_CLOEXEC in most fcntl.h headers, and import __ASSUME_O_CLOEXEC from glibc. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* honour NO_LONG_DOUBLE_MATHBernhard Reutner-Fischer2009-08-302-2/+6
| | | | | | | | This fixes compilation errors on hosts that turn off long double support for C99 like powerpc32. Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

* enable nanosecond stat support for everyoneMike Frysinger2009-07-262-7/+4
| | | | | | | | | | | | | Fill out the stat structure so that the nanosecond resolution support is always available. There is a small code size increase for a few ports (three additional assignments in xstatconv), but otherwise everything should remain the same. While we're here, punt __old_kernel_stat from the few headers that still define it as it is unused in uClibc and causes compile errors after these nanosecond changes.

* syscall: unify part 2: NCS varietyMike Frysinger2009-07-091-4/+4
| | | | | | | Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* syscall: unify common syscall definesMike Frysinger2009-07-081-168/+233
| | | | | | | | | Unify all the common syscall defines in syscalls-common.h and scrub all the duplicated code from relevant ports. This should also make converting existing ports to INLINE_SYSCALL() much easier as they don't have to get lost in all the unrelated noise, as well as creating new ports. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* uClibc_arch_features: sync defines between portsMike Frysinger2009-07-031-0/+9
| | | | | | | Make sure each arch has the same complete list to make comparing between them easier. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* A patch from our Blackfin repository, originally from Jie Zhang. This fixesBernd Schmidt2008-01-171-3/+0
| | | | | | | | | | | | | a problem where the linker was trying to use the wrong symbol name for the init function. Define SYMBOL_PREFIX as _ in Rules.mak for h8300, bfin, i960, microblaze, and v850. Add -D__UCLIBC_UNDERSCORES__ in CFLAGS for targets which define SYMBOL_PREFIX as _. Remove defines and undefs from uClibc_arch_features.h of each target. Add $(SYMBOL_PREFIX) to __uClibc_init when passed by ld option -init.
