2016-11-27remove UCLIBC_HAS_LFSWaldemar Brodkorb
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

2013-04-07linux: pread/write: fix 64bit handlingMike Frysinger
The syscall on 64bit ports takes 4 args as there is no need to split up the value into two args. Add support for that to the common code. Once we fix that, the mips code can now leverage it for its 64bit and 32bit needs. However, we can't just drop it entirely yet because its n32 ABI needs special handling to treat it like a 64bit port. This does change the existing behavior which treats the n32 like a 32bit port, but we want to do this. In the future, we'll probably have to introduce a define for this as it currently affects x86_64/x32 and mips/n32. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-04-01linux: pread/write: convert to SYSCALL_ALIGN_64BITMike Frysinger
The pread64/write64 syscalls have the 64bit register align issue for all arches. Use this new define so we can merge the powerc/xtensa versions back into the common code. SuperH is funky and also allows us to do this. We should be able to merge the mips version too, but that'll require someone to take a closer look as the current stuff doesn't look quite right.

2012-05-30pread/pwrite: drop fallback funcsMike Frysinger
Linux has provided these functions since the 2.1.x era, so no need to keep these around. We'd rather find out when things are missing (and fix that) than fall back to the unsafe hacks. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-05-30pread/pwrite: handle renamed syscalls in common/ppc/xtensa codeMike Frysinger
Some arches got this fix, but many did not. So copy the ifdef logic to the ones that missed it to fix behavior in linux-2.6+. URL: https://bugs.busybox.net/show_bug.cgi?id=5258 Reported-by: David Laight <david.laight@aculab.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2002-10-31Ok, this commit is _huge_ and its gonna change the world. I'veEric Andersen
been working on a new config system on and off for about 6 months now, but I've never been fully satisfied. Well, I'm finally am happy with the new config system, so here it is. This completely removes the old uClibc configuration system, and replaces it with an entirely new system based on LinuxKernelConf, from http://www.xs4all.nl/~zippel/lc/ As it turns out, Linus has just merged LinuxKernelConf into Linux 2.5.45, so it looks like I made the right choice. I have thus far updated only x86. I'll be updating the other architectures shortly. -Erik
2002-08-09pread and pwrite were broken in several ways:David McCullough
* pwrite was using the write system call. * SYSCALL_INLINE was only defined for pread and reused by pwrite meaning pwrite did a pread :-). * The kernel pread/pwrite interfaces always take a 64bit value. So the libc versions must do the LONG_LONG_PAIR stuff otherwise the pread/pwrite calls will not work. These guys are working now for SH at least (and I can format my DiskOnChip again ;-)
