2015-12-17libc/stdio: Rework custom streams interface similar to glibc.Waldemar Brodkorb
Save 20 bytes per FILE structure, avoid indirect call for read/write/seek/close operations for normal streams. Additionally, custom streams has fileno = -2 now, like in glibc. bloat-o-meter report (UCLIBC_HAS_GLIBC_CUSTOM_STREAMS=y): function old new delta fopencookie 69 131 +62 ftello64 233 260 +27 fseeko64 298 319 +21 fclose 423 442 +19 .rodata 16696 16708 +12 fileno_unlocked 53 45 -8 __ns_name_pack 859 851 -8 vswscanf 184 144 -40 vdprintf 231 187 -44 vsscanf 210 151 -59 vswprintf 269 201 -68 vsnprintf 249 181 -68 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 5/7 up/down: 141/-295) Total: -154 bytes Signed-off-by: Leonid Lisovskiy <lly.dev@gmail.com> Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

2015-12-11Revert "fix tst-signal7 failure"Waldemar Brodkorb
This reverts commit ea21c7610aa1131b37a4533cf13dd89f727fb83f. This was accidently pushed, before first coffee. Sorry this is a bad commit.
2015-12-11config: allow config to handle longer path namesMarkus Mayer
The current (arbitrary) limit of 128 characters for path names has proven too short for Android builds, as longer path names are used there. Change conf.c, so it can handle path lengths up to PATH_MAX characters. Signed-off-by: Markus Mayer <mmayer@broadcom.com>

2015-12-09arc: add ulps file for math testsWaldemar Brodkorb
Using non-generic ulps file reduces failure counts for math tests. Generated with nsim emulator running test-{double,idouble,float,ifloat} -u and gen-libm-test.pl on the build host.
2015-12-09do not hardcode path to perlWaldemar Brodkorb
When cross-compiling on other Unix systems like FreeBSD 10.x, perl is not in /usr/bin. Use env to find the perl interpreter and use no fixed path when executing via make.
2015-12-09sh: add back sh2 specific assembly for clone()Waldemar Brodkorb
In gcc 5.x there is a compile failure, for sh2 builds as shad no longer is accepted. Strange that it is working for 4.9.x. Add back old assembly code.

2015-12-09Reduce the initial buffer size for open_memstreamWaldemar Brodkorb
Reduce the initial buffer size for open_memstream (used by vasprintf), as most strings are usually smaller than that. Realloc the buffer after finishing the string to further reduce size. Problem appears in case of UCLIBC_HAS_GLIBC_CUSTOM_STREAMS=y, see http://dev.openwrt.org/ticket/13024 Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Leonid Lisovskiy <lly.dev@gmail.com> Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

2015-12-08sync with glibc, add some missing definesWaldemar Brodkorb
These are already used by some applications, so add it.

2015-12-05good by niosWaldemar Brodkorb
Get rid of NIOS support. We try to support NIOSII.
2015-12-05good by e1Waldemar Brodkorb
It is marked as broken and it seems you can't get any hardware for that anymore.
2015-12-05good bye vaxWaldemar Brodkorb
I mailed with Jan-Benedict Glaw, it seems VAX on Linux is really a lot of work todo and uClibc support didn't work ever.
2015-12-05remove sh64 supportWaldemar Brodkorb
No real hardware available. The project for sh64 with sh5 seems dead since 10 years. Gcc will remove support for it soon.
2015-12-05remove __UCLIBC_ASM_GLOBAL_DIRECTIVE__Waldemar Brodkorb
.globl can be used for every architecture so remove the define. Sync with GNU C library.
2015-12-05remove __UCLIBC_HAVE_ASM_GLOBAL_DOT_NAME__Waldemar Brodkorb
It's even no longer required for non-ported ppc64 architecture. Sync with GNU C library. This simplify the macros in include/libc-symbols.h.
2015-11-30bfin: fix clashing with newer gccWaldemar Brodkorb
See here for a discussion about the problem: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47779 Latest gcc/binutils git can generate a working uClibc-ng toolchain. Binaries tested on Arcturus uCBF54x board via chroot from original firmware.
2015-11-30bfin: use vfork.S againWaldemar Brodkorb
Actually revert 711ad9f92c1cf992c4a3d9f4f709bd692be7789c, as it breaks vfork() on real hardware. So the common implementation no longer works for bfin.

2015-11-23xtensa: remove ldso workaround by real pointer checkWaldemar Brodkorb
An abort() is only generated when gcc does not implement a trap handler for the target architecture. This fixes the abort() generation. Latest gcc git master also contains a trap handler for xtensa. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Walemar Brodkorb <wbx@uclibc-ng.org>
2015-11-23mips: remove ISA choiceWaldemar Brodkorb
We don't add cpu specific CFLAGS to the build, so the ISA config symbols for MIPS are noops. Simple remove them. Reported-By: Bryan Hundven <bryanhundven@gmail.com>

2015-11-13i386: use socketcall even if newer linux exposes direct syscallsWaldemar Brodkorb
The changeset 9dea5dc921b5f4045a18c63eb92e84dc274d17eb in the Linux kernel expose the direct syscalls for sockets. For example udhcpc then will use sendto syscall directly and get an EINVAL error. Disable direct syscalls as it was done for SPARC in the past. Musl and GNU libc are not affected, as they already disable direct socket syscalls on i386.

2015-10-22alpha: add special umount2 handlingWaldemar Brodkorb
Only on Linux alpha __NR_oldumount is defined and a umount not umount2 syscall, but with two parameter is used. Add special handling for it and an alias for umount2() users. There was a discussion about this special handling, but it seems it was never committed upstream: http://marc.info/?l=linux-alpha&m=137455037930738&w=2 Runtime tested with qemu-alpha and a statically linked busybox binary.
