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).

uclibc config option macros (aligning SH to all other archs).
Changes applied as below:
__CONFIG_SH4__ -> __SH4__
__CONFIG_SH2__ -> __sh2__
__CONFIG_SH2A__ -> __SH2A__
Note: pay attention to capital letters

supports this feature. SH4 will use this in some aseembly files
for the NPTL implementation. Add now safely on trunk.

Tested successfully on i386..

(glibc community refused to apply a my patch for this :-) )

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.

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.

- synch F_LINUX_SPECIFIC_BASE related fcntls for all arches
|
|
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
|

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.

applications stop using _syscall#() and use syscall() instead. Cleanup
internal handling of syscall includes to use the correct header file.

* libc/sysdeps/linux/sh/vfork.S: Use __SH_SYSCALL_TRAP_BASE.
Also use __CONFIG_SH2__ rather than __sh2__, for consistency.
* libc/sysdeps/linux/sh/syscall.c: Use __SH_SYSCALL_TRAP_BASE.

* libc/sysdeps/linux/sh/bits/syscalls.h (__SH_SYSCALL_TRAP_BASE):
New.
Use instead of hard-coded trap numbers in the various __NR_<name>
macros.
* libc/sysdeps/linux/sh/clone.S: Use __SH_SYSCALL_TRAP_BASE.
Also use __CONFIG_SH2__ rather than __sh2__, for consistency.

__HAVE_SHARED__ is not set.
* libc/sysdeps/linux/sh/pipe.c (pipe): Use __SH_SYSCALL_TRAP_BASE.

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.
