This commit includes following features.
1. Support NPTL/TLS
2. Add libm function which is used to handle FP rounding and excpetions
(ex: fclrexcpt,fedisblxcpti,feenablxcpt... )
3. Add *context function for operating user context
(ex: setcontext,getcontext,makecontext... )
4. Change the return flow from signal handler
5. Cleanup of old code
The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1,
which are related to timing accuracy. (math and locale tests are disabled)

A wrong filename was present in Makefile.in leaving libintl.h installed
even if libintl support is disabled leading to wrong configure checks
by other packages.

This removes _DYNAMIC@gotpc from elf_machine_load_address()
This is a seperate commit to callout the fact that old code was actually
broken but was NOT caught since it never gets called (and will never be)
since ld.so only calls it if kernel doesn't pass AT_BASE auxvt, which is
not true for Linux.
if (!auxvt[AT_BASE].a_un.a_val)
auxvt[AT_BASE].a_un.a_val = elf_machine_load_address();
So while the intent was to remove _DYNAMIC@gotpc construct, we need to
come up with something which works.
The build time address computation of .dynamic which works well is:
- "ld %1, [pcl, _DYNAMIC@gotpc] \n"
+ "ld %1, [pcl, _GLOBAL_OFFSET_TABLE_@pcl] \n"
However the runtime address of .dynamic can only be generated with
"add %0, pcl, _DYNAMIC@pcl \n"
which unfortunately is what is currently broken as it is converted to
i_GLOBAL_OFFSET_TABLE_t and thus refers to runtime address of .got and
not .dyanmic
Thus we resort to using an arbit symbol _dl_start at the expense of an
extra GOT entry and a bogus R_ARC_NONE relo in ldso itself which now
needs to be ignored.

This converts elf_machine_dynamic() to not use the _DYNAMIC@xx construct
which was historically converted by assembler into _GLOBAL_OFFSET_TABLE
Now that "hack" is being removed from assembler, we need to make sure
that no code relies on that magic "conversion".

We do not support symbol versioning, so remove these weak aliases.

Follow documented behaviour:

Sync with GNU libc behaviour.

Add the wrappers unconditionally, because kmod package
still uses them.
|
|
|
|
|
|
The syscall wrappers are not required and other C libraries
do not provide them. Busybox modutils.c must be patched so
that syscall() is used for uClibc-ng.

Remove __UCLIBC_HAS_OBSTACK__ as it isn't very uptodate and
maintained part. It shouldn't be required for any software and
mostly shipped with stuff which use it. (f.e. binutils-gdb)
|
|
This option is enabled for a long time and I see no
useful case where we should be incompatible to glibc here.

Commit cee0b058fa0b4501b289a2da365182d60314d746 ("add aligned_alloc
required for latest gcc libstdc++") added the prototype of
aligned_alloc() to <stdlib.h>. This prototype contains
'__attribute_alloc_size__ ((2))', but this is not defined anywhere in
uClibc-ng.
This commit addresses that by adding the relevant definition in
<sys/cdefs.h>, borrowed from glibc.

These adds the stubs from gettext-tiny 0.0.5
from here:
https://github.com/sabotage-linux/gettext-tiny
|

To use it enable UCLIBC_HAS_LIBICONV, then iconv_open/iconv_close
should be available.

uClibc-ng 1.0.20 fixed static linking with "libdl" by adding all libdl functions
into the libc. On xtensa, though, libdl contains an unresolved reference that is
satisfied by the ld.so - which is not a part of the linking in a static case.

Fixes following problem, when trying to compile a simple
C application statically with a FDPIC toolchain (for example
with Blackfin architecture):
lib/libc.a(libdl.os): In function `do_dlclose':
(.text+0x6be): undefined reference to `_dl_free'

As __UCLIBC_HAS_GETTEXT_AWARENESS__ is never defined, this is
mostly dead code. It is planned to integrate libiconv-tiny
and gettext-tiny into uClibc-ng after the next release, so
that more software packages can be used without modification.
Remove any _/_N macro usage.
