2016-09-30ubacktrace/uargp: remove unneeded and false linker scriptsWaldemar Brodkorb
2016-09-27bump for releasev1.0.18Waldemar Brodkorb
2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance
2016-08-27remove DOMULTI supportWaldemar Brodkorb
A single test with targeting ARM showed that this feature seems bit rotted. Remove DOMULTI and simplify Makefiles.

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>
2016-06-23ARC: remove deprecated -msoft-float from CFLAGSAlexey Brodkin
"-msoft-float" makes no sense for ARC because there's no such thing as "-mhard-float" on ARC. Instead we use our own "-mfpu=XXX" option when a particular floating-point related HW feature is enabled in the ARC core. We used to live with that phony option for quite some time but with migration to newer GCC following warning now appears: -------------------->8----------------- arc-linux-gcc: warning: ‘-msoft-float’ is deprecated cc1: warning: ‘-msoft-float’ is deprecated [enabled by default] -------------------->8----------------- And that warning gets printed for each invocation of gcc with the option in question, which makes compilation output barely readable. So we disable that phony option for ARC now.

Both $(CC_FLAG_ASNEEDED) and $(CC_FLAG_NO_ASNEEDED) never become "y", must check for non-empty strings. To keep make 3.80 compatibility "$(if" used only. Fixes: 7da4d1e7 "buildsys: do not use $(and)". Signed-off-by: Leonid Lisovskiy <lly.dev@gmail.com>
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

2016-03-31arm: simplify handling of Thumb related optionsThomas Petazzoni
Currently, the Thumb support on ARM has three related Config.in options, which are not trivial for users to understand, and are in fact not needed: - The USE_BX option is not needed: knowing whether BX is available or not is easy. If you have an ARM > v4 or ARMv4T, then BX is available, otherwise it's not. This is the logic used in glibc. - The USE_LDREXSTREX option is not needed: whenever Thumb2 is available, ldrex/strex are available, so we can simply rely on __thumb2__ to determine whether ldrex/strex should be used, without requiring a Config.in option. - Once USE_BX and USE_LDREXSTREX are removed, the only thing left that COMPILE_IN_THUMB does is to set -mthumb. This makes the option unnecessary, as on ARM at least, the user is already supposed to pass -march=<foo> or other compiler options tuning the library for a specific ARM variant. There is no reason to do otherwise for Thumb, which allows to get rid of the COMPILE_IN_THUMB option. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

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.

2016-01-09fix compile with DODEBUG=yWaldemar Brodkorb
Since more projects using two-stage cross-compile process we cannot add libgcc_eh.a unconditionally. We must check if a real file is referenced by the cross-compiler. Toolchains with --disabel-shared build have a single libgcc.a containing all required symbols. Tested with a debug build for x86.
2016-01-02remove deprecated architectures v850/i960Waldemar Brodkorb
Both architectures are more or less deprecated. No Linux upstream support, no gcc support for uClinux.
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.

With older gcc than 4.9.x, this breaks the build. These specific compiler flags belongs better to your favorite build system.
