2009-07-09syscall: unify part 2: NCS varietyMike Frysinger
Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-09sh: Change __HAVE_SHARED__ to __PIC__Peter Griffin
Generate PIC relocations when __PIC__ is defined rather than __HAVE_SHARED__ (like other architectures). Signed-off-by: Peter Griffin <pgriffin@mpc-data.co.uk> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2009-07-08syscall: unify common syscall definesMike Frysinger
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>
2009-07-03uClibc_arch_features: sync defines between portsMike Frysinger
Make sure each arch has the same complete list to make comparing between them easier. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-05-05Add position independent code for crt1.S.Carmelo Amoroso
This will generate a Scrt1.o that is linked to executabled when compiled as PIE code (position independent executable) without requiring relocation in .text section (not allowed on uclibc/sh4).

(glibc community refused to apply a my patch for this :-) )
2008-09-04Kill off the GOT lookup for init/fini in the sh crti.S. This wasPaul Mundt
inversely conditional on __HAVE_SHARED__, which has been broken since the time it was copied in originally. The compiler properly generates the GOT references on its own, negating the entire purpose for the init/fini reference.
2008-08-08Fix SH ldso sequence startup.Carmelo Amoroso
Pass via r4 the rtld finalizer _dl_fini to the user application. This will be the 6^ arg of __uClibc_main and will be registered with 'atexit'. In this way the dynamic linker will be able to call destructors defined within the loaded DSOs.

2008-01-17A patch from our Blackfin repository, originally from Jie Zhang. This fixesBernd Schmidt
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.

Hi All, this patch fixes a mismatch in ucontext struct between uClibc and kernel. In this way a signal handler installed by sigaction can access to the whole machine state correctly. This can be applied both to trunk and nptl branch
2007-04-30Carmelo AMOROSO writes:Mike Frysinger
running LTP test suite on uClibc-nptl for sh4 I found a bug into pread and pwrite functions. When the offset is negative it is not correctly handled due to a missing shift operation, so it is passed to the syscall as the highest unsigned positive value.

Also use __CONFIG_SH2__ rather than __sh2__, for consistency. * libc/sysdeps/linux/sh/crti.S: Disable GOT-related code if __HAVE_SHARED__ is not set. * libc/sysdeps/linux/sh/pipe.c (pipe): Use __SH_SYSCALL_TRAP_BASE.
2006-08-25Bump SHMLBA up to a sensible size for dcache alias avoidance to coincide withPaul Mundt
the kernel's get_unmapped_area() behaviour. Ideally this should be more tightly packed based off of the L1 dcache shape, once we're able to handle it through the auxiliary vector.
