* */crtn.S: Remove .size directive for _init and _finiBernhard Reutner-Fischer2011-05-101-2/+0
| | | | | | | | | These are split across objects so setting size does not (and never did) work since the expression cannot be computed at assembly time. This avoids errors from recent (> 2.21) gas. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

* nptl: sysdep headers re-factoringCarmelo Amoroso2010-02-091-0/+277
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch will re-factor and simplify sysdep headers handling for nptl branch. The reason is to use some useful macros in asm code (i.e. ENTRY()) that are available only into nptl branch because are defined in sysdep.h header under the nptl folder even if they are not related to NPTL at all (this was likely due to a bad choice done at the early stage of NPTL porting). This is a required steps for integrating into master branch some asm code available in nptl branch for sh4. The main changes are described below: nptl/sysdeps/generic/sysdep.h (moved) ---> libc/sysdeps/linux/common/sysdep.h nptl/sysdeps/arm/sysdep.h (moved) ---> libc/sysdeps/linux/arm/sysdep.h nptl/sysdeps/sh/sysdep.h ---------------------| nptl/sysdeps/unix/sh/sysdep.h ----------------| nptl/sysdeps/unix/sysv/linux/sh/sysdep.h -----| nptl/sysdeps/unix/sysv/linux/sh/sh4/sysdep.h -| |(merged) ---> libc/sysdeps/linux/sh nptl/sysdeps/unix/sysdep.h (deleted) Similarly the mips and arm sysdep.h should be merged and updated as for sh arch.

* 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>

| | | | | | | | | | | | | | | | | | | | 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>

* 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>

* 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.
