* libc_arm: avoid multiple version of __aeabi_unwind_cpp_pr dummy codeCarmelo Amoroso2012-01-271-2/+1
| | | | | | | | | Do not pollute libraries with its own implementation of __aeabi_unwind_cpp_pr1 code. Just add it to uclibc_nonshared.a archive and share it. This fixes build issue with static linking of application due to multiple symbol definition in libgcc_eh-a and libpthread.a or librt.a Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

* ARM: remove EABI/OABI selectionYann E. MORIN2011-06-112-4/+9
| | | | | | | | | | | | | | Rely on the compiler to be properly setup for the default ABI. When installing-headers, there are two cases: - NPTL: no issue, a cross-compiler is already expected - LinuxThreads: no issue, EABI/OABI has no impact on installed headers. Signed-off-by: "Yann E.

* ARM: detect BX availibility at build timeYann E. MORIN2011-06-111-1/+8
| | | | | | | | | | | | | | | The "use BX" option is now a suggestion that BX be used if available. Use a macro to detect if BX is available at build time. If so, and the user requested it be used, then use it. Otherwise, error out. Macro courtesy Khem RAJ: http://lists.uclibc.org/pipermail/uclibc/2009-April/042301.html Signed-off-by: "Yann E.

| | | | | | | | | 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/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Most ports have the same exact mman bit defines, so let's unify things like the linux kernel has with the asm-generic efforts.

* 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.

* Fix ARM syscall argument loading.Joseph Myers2009-07-141-14/+21
| | | | | | | | | | | This patch is a uClibc equivalent of <http://sourceware.org/ml/libc-ports/2008-11/msg00006.html>, to compute all syscall arguments on ARM in temporary variables before loading them into register variables. The principle is as for that glibc patch; the problem I actually observed was a GCC internal compiler error building ld.so for Thumb-2. Signed-off-by: Joseph Myers <joseph@codesourcery.com>

* syscall: unify common syscall definesMike Frysinger2009-07-081-71/+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.

* Fix Thumb-2 setjmp.Joseph Myers2009-06-301-1/+1

| | | | | | | | | | | The ARM EABI has a document CLIBABI specifying various __aeabi_* functions and variables to be provided for the use of portable objects that can be linked with different EABI-conforming C libraries. __aeabi_stdin, __aeabi_stdout and __aeabi_stderr were missing in uClibc; this patch (originally from Nathan Froyd and for glibc) adds them.
