2017-01-22nds32: add NPTL/TLS, *context function, libm changes and code cleanupVincent Ren-Wei Chen
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) Signed-off-by: Vincent Ren-Wei Chen <vincentc@andestech.com>

2016-12-21remove obstack supportWaldemar Brodkorb
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)
2016-12-20sys/cdefs.h: add definition of __attribute_alloc_size__Thomas Petazzoni
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. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2016-12-20add stub implementation for libintl/gettextWaldemar Brodkorb
These adds the stubs from gettext-tiny 0.0.5 from here: https://github.com/sabotage-linux/gettext-tiny
2016-12-14add libiconv-tiny implementationWaldemar Brodkorb
To use it enable UCLIBC_HAS_LIBICONV, then iconv_open/iconv_close should be available.

2016-12-02remove libintl stub and libintl.h headerWaldemar Brodkorb
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.

2016-11-04nios2: sync support with glibcWaldemar Brodkorb
Only static linking is supported for now. More debugging and analyzing for ld.so, TLS and NPTL is required. But at least you can bootup a static root fileystem in Qemu.

Fixes a compile error for samba 4.5.0. Reported-by: Gustavo Zacarias <gustavo@zacarias.com.ar>
2016-06-30nds32: add support for new architectureWaldemar Brodkorb
Add support for Andes Technology NDS32 architecture. See here http://www.andestech.com/en/index/index.htm for more informaton. Verification of the port from an older uClibc port was done on a sponsored AG101p board. The testsuite only has 5 errors, three are related to an existing bug in dlclose() with LT.old, also happening on cris32 and m68k. Failures to fallocate/posix_fallocate are unresolved. Thanks to Andes Technology sponsoring the hardware and being very helpful while doing the uClibc-ng porting. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>
2016-06-15sysconf: Support _SC_(AV)?PHYS_PAGES.Nicolas Cavallari
Do it by following the trail of the existing commented code, which implemented it by calling get_phys_pages() and get_avphys_pages(). This patch implements these two functions, which are also glibc extensions. Some program/libraries (e.g. libuv) assumes that sysconf(_SC_PHYS_PAGES) works on linux and never check for -1, thus they report an insane amount of memory.

2016-05-18remove linuxthreads.new, rename linuxthreads.oldWaldemar Brodkorb
Linuxthreads.new isn't really useful with the existence of NPTL/TLS for well supported architectures. There is no reason to use LT.new for ARM/MIPS or other architectures supporting NPTL/TLS. It is not available for noMMU architectures like Blackfin or FR-V. To simplify the live of the few uClibc-ng developers, LT.new is removed and LT.old is renamed to LT. LINUXTHREADS_OLD -> UCLIBC_HAS_LINUXTHREADS

2016-03-31bits/byteswap-common.h: import recent headers from glibcAnthony G. Basile
On systems where uClibc doesn't provide an arch specific byteswap.h, we fall back on bits/byteswap-common.h. However, there is a bug in this header in the __bswap_constant_64(x) macro. If, for example, a double is passed, we get 'invalid operands to binary &' in which we mismatch a 'double' and 'long long unsigned int'. The newer glibc headers fix this and so we import them. Also, since the inclusion of byteswap.h is not appropriate for assembly code, we guard a portion of endian.h which uses byteswap.h from inclusion in any assembly. This is needed, for example, for f2fs-tools 1.6.0 on 32-bit big endian PowerPC. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2016-02-24Advertise obstack only when chosenAnton Kolesov
This is similar to this patch for GNU glob: ff6ce3999db93a52d1cd22510f8508b660ddf54e. The problem is that libiberty/obstack.c file checks for _GNU_OBSTACK_INTERFACE_VERSION == _OBSTACK_INTERFACE_VERSION and elides libiberty obstack implementation if there is already a compatible implementation in libc. Therefore define should be set only when obstack is actually selected, otherwise it is not possible to build binutils and gdb with uClibc.

2016-02-19mark a.out support as not availableWaldemar Brodkorb
Some architectures do not provide the Linux header, so packages which include a.out.h might fail. Some discussions seen on the buildroot mailinglist.
2016-02-07frv: resurrect port somehow, totally untestedWaldemar Brodkorb
The FR-V port is really broken, and I have no emulator or hardware for this platform. I tried to get some hardware from RedHat, who made the FR-V port initially. Unfortunately Fujitsi didn't agreed to sent me some of their unused spare hardware lying @RedHat. As I invested some time to get stuff compiled, I decided to add the code and may be anytime later I can gain access to some emulator or hardware. GDB simulator for FR-V doesn't support booting Linux AFAIK.
2016-02-02include/netdb.h: Do not define IDN-related flags.Thomas Claveirole
getaddrinfo() does not implement IDN encoding, and always fail when provided an IDN flag (e.g., AI_IDN) with EAI_BADFLAGS. Some packages (such as the VLC media player) check for AI_IDN before they use it; providing an unimplemented AI_IDN in the libc makes these package fail. As a result they make calls to getaddrinfo() with AI_IDN that always fail while they could have made successful calls without AI_IDN instead. Thus, do not define IDN flags: it is better not to compile rather than to compile a code that always fail. Signed-off-by: Thomas Claveirole <thomas.claveirole@green-communications.fr>
2016-01-31ldso: Use single rtld_flags interpretation through all the callsLeonid Lisovskiy
Implement single rtld_flags interpretation through all the do_dlopen()/_dl_load_shared_library()/_dl_load_elf_shared_library() calls chain. This adds the ability to use the flags, passed to dlopen(), in all underlaying functions and implement rtld_flags inheritance. Saves a few bytes code.

2016-01-01Add argp implementationSalvatore Cro
Argp is an advanced support for parsing unix-style argument vectors. In addition to the common getopt interface, it provides automatic response to `--help' and `--version' options and use of custom parser in conjunction with argp native option parser, among others. Argp support is required by elfutils package and prelink. In uClibc argp functionalities has been moved from C library to libuargp.so Further the libc.so linker script contains an AS_NEEDED entry so that it doesn't need to link libuargp.so explicitely. Disable argp test if feature disabled.
