2015-03-09remove NAN selection, better do it in your build systemWaldemar Brodkorb
With older gcc than 4.9.x, this breaks the build. These specific compiler flags belongs better to your favorite build system.

2015-02-20Allow use of executable RUNPATH/RPATH when finding libraries.Steve Ellcey
This option will modify ldso so that it will use the executables RUNPATH/RPATH to find to find libraries even though this behavour is not standard. Setting this option causes the uclibc dynamic linker behavour to match the glibc dynamic linker.

2015-02-16ARC: Conditionalise certain relocations as provided by TLS tools onlyVineet Gupta
uClibc mainline supports NPTL which in turns depends on TLS support in the tools (gcc/binutils), which is yet to be merged in dev branches. However there is some non NPTL code in uClibc, added as part of NPTL effort, which relies on certain relocations only provided by NPTL binutils. As a result building the current upstream even for LT.old breaks. So conditionalize that code on tools, bu tin lack of specific versions, we use NPTL enabling as a sign the tools are equipped to handle those relos.

2015-02-12Update MIPS configuration rules.Steve Ellcey
Add a configuration choice for the NaN format on MIPS (either the standard (legacy) format or the newer IEEE 2008 format. Change how CPU_LDFLAGS are set for MIPS. Use the same value as CPU_CFLAGS since CC is used to do linking. This ensures consistency between compiles and links and adds support for N32 ABI to linking.

2014-11-10statfs: fix compile error when UCLIBC_LINUX_SPECIFIC is not setAnthony G. Basile
statfs() is a Linux-specific function. When building without UCLIBC_LINUX_SPECIFIC set, libc_hidden_proto(statfs) in include/sys/statfs.h is unmatched with libc_hidden_def(statfs) in libc/sysdeps/linux/common/statfs.c, leading to a compile error. This patch fixes this, as well as adds statfs() to the list of Linux-specific functions in extra/Configs/Config.in. Signed-off-by: Anthony G. Basile <blueness@gentoo.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2014-10-14reduce the list of supported architecturesWaldemar Brodkorb
As most of these architectures either does not compile or embedded hardware is difficult to get, I disable them for now. I do not remove the existing code and hope to enable many of them in the future, but not for 1.0.
2014-10-10c6x: disable it at the momentWaldemar Brodkorb
There is a NPTL port of uCLibc for c6x, but it doesn't work with uClibc master. May be someone with real hardware could sync it. Unfortunately I got no respone from Aurelien and no response on the mailing list.
2014-09-26libpthread: disable unimplemented configurationsWaldemar Brodkorb
When NPTL is available for an architecture just allow the use of it. If NPTL is not available for an architecture, allow to choose between LT and LT.old. This minimizes misconfiguration of threading library.
2014-09-26enable this symbol by defaultWaldemar Brodkorb
disabling this results in non-working toolchain building, so better do not allow anyone to disable it.

2014-09-09libc: add fallocate() and fallocate64()Anthony G. Basile
We add the Linux-specific function fallocate() which allows the user to directly manipulate allocate space for a file. fallocate() can operate in different modes, but the default mode is equivalent to posix_fallocate() which is specified in POSIX.1. Recent releases of e2fsprogs 1.42.11 and above expect fallocate64() to be available. Signed-off-by: Anthony G.

2013-05-19i386: punt all config options that just control -marchMike Frysinger
You can set these yourself in your CFLAGS, and our list is incomplete and pointless (we agreed some time ago to stop doing this). We keep around CONFIG_[3456]86 because it is used to select between different optimized subdirs of handcoded assembly. Also take this opportunity to up the default to i686. If you're using an older cpu, then you can handle changing this yourself. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2013-03-14Add support for the Meta architectureMarkos Chandras
Meta cores are 32-bit, hardware multithreaded, general purpose, embedded processors which also feature a DSP instruction set, and can be found in many digital radios. They are capable of running different operating systems on different hardware threads, for example a digital radio might run RTOSes for DAB decoding and audio decoding on 3 hardware threads, and run Linux on the 4th hardware thread to manage the user interface, networking etc. HTPs are also capable of running SMP Linux on multiple hardware threads.

2013-03-14libpthread: linuxthreads.old: Allow building for no-legacy-syscalls ABIVineet Gupta
Since NPTL port to an ARCH can be non-trivial, we must allow the legacy pthread lib to be built for the common-generic syscall ABI Note that only linuxthreads.old is allowed, since "newer" linuxthreads relies on sysctl which the ABI no longer provides.
