* sh_nptl: Enable CFI directives for shCarmelo Amoroso2008-09-182-0/+9
| | | | | | | | | Enable CFI directives for sh to add proper CFI information into assembly functions. This provides stack frame information used during stack unwinding as well by debugger for backtracing.

* Fixes posix_fadvise[64] functions to return the Carmelo Amoroso2008-09-185-155/+189
| | | | | | | | | | error number in case of failure instead of -1 and setting errno, according to SuSv3 (IEEE Std 1003.1 2004 edition) specification. Also refactor sysdep.h and syscalls.h moving INTERNAL_SYSCALL macro to the latter (as other archs do in uclibc).

The compiler properly generates the GOT references on its own, negating the entire purpose for the init/fini reference. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

* Fix SH ldso sequence startup.Carmelo Amoroso2008-08-082-4/+20
| | | | | | | | | | | | | | | | | | 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.
