* libc_sh: Add a sysdep header for shCarmelo Amoroso2010-02-101-0/+277
| | | | | | | | | | | | A new sysdep header for sh (ported from NPTL branch) to provide some useful macros in asm code: ENTRY: an entry point visible from C PSEUDO: a wrapper for syscall with proper errno checking SYSCALL_ERROR_HANDLER: errno check (suitable for TLS) This will help in NPTL integration.

* sh: Add a prototype for the gcc __set_fpscr internal functionCarmelo Amoroso2009-12-031-1/+3
| | | | | | | | | The sh port uses the gcc __set_fpscr internal function, but neither gcc nor glibc creates a prototype for it. This leads to a bunch of random warnings about implicit decls during the build. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* bits/mmap.h: unify ala linux asm-generic effortsMike Frysinger2009-11-231-103/+0
| | | | | | | | | | Most ports have the same exact mman bit defines, so let's unify things like the linux kernel has with the asm-generic efforts. A few ports are left behind as they are non-trivial to merge -- the arch maintainers can tackle it if they care. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Fix SH bits/kernel_types.h for new kernel headers.Joseph Myers2009-10-141-1/+2
| | | | | | | | Recent SH kernel headers merge 32-bit and 64-bit headers, changing the include guards on asm/posix_types.h in the process; update uClibc code depending on those include guards. Signed-off-by: Joseph Myers <joseph@codesourcery.com>
* 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>

* sh/user.h: clean up conflicts from kernel user.hAndrew Stubbs2009-09-151-0/+11
| | | | | | | | | | | | This patch makes sufficient modifications to the SH sys/user.h to be able to build and run gdbserver with Linux kernel 2.6.30. The problem is that both the kernel and library headers define the same symbols, thus making it impossible in include both headers. The patch undefines the kernel symbols in favour of the library symbols. Signed-off-by: Andrew Stubbs <ams@codesourcery.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* honour NO_LONG_DOUBLE_MATHBernhard Reutner-Fischer2009-08-301-0/+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>
* build: Include Makefile.commonarch from common Makefile.inCarmelo Amoroso2009-07-291-2/+0
| | | | | | | | Avoid including akefile.commonarch in each Makefile.arch. Include it instead from Makefile.in just after the arch specific Makefile.arch Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* enable nanosecond stat support for everyoneMike Frysinger2009-07-261-14/+6
| | | | | | | | | | | | | 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 Frysinger2009-07-091-23/+0
| | | | | | | Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sh: Change __HAVE_SHARED__ to __PIC__Peter Griffin2009-07-093-5/+5
| | | | | | | | 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>
* syscall: unify common syscall definesMike Frysinger2009-07-081-134/+0
| | | | | | | | | 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.

| | | | | | | | | 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).

| | | | | | | | 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
