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.

2015-02-20sync_file_range: fix standard UCLIBC_SYSCALL_ALIGN_64BIT handlingVineet Gupta
Currently UCLIBC_SYSCALL_ALIGN_64BIT is not explicitly handled. Fix that and make sure the special handling is done for powerpc/xtensa which use UCLIBC_SYSCALL_ALIGN_64BIT but don't use hole punched syscall handler in kernel.

2015-02-20posix_fadvise: handle 2 variants for SYSCALL_ALIGN_64BITVineet Gupta
arm/powerpc/xtensa pass @advice as 2nd arg to syscall (vs. canonical 4th) Current code however does this for UCLIBC_SYSCALL_ALIGN_64BIT which powerpc/xtensa also happen to define. This is not true for ARCv2 ISA and possibly other arch of future with 64-bit even register requirement, which uses the standard syscall handler in kernel. Fix that by providing 2 variants of SYSCALL_ALIGN_64BIT Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Baruch Siach <baruch@tkos.co.il> Cc: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

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.

2014-12-15mkostemp: fix implementationAnthony G. Basile
mkostemp(char *template, int flags) generates a unique temporary filename from a template. The flags parameter accepts three of the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The current implementation of mkostemp(3) does not respect the flags and in fact confuses the flags with the file mode which should always be S_IRUSR | S_IWUSR. This patch corrects this issue.

2014-12-15stdio: Fix printing 0.0Bernhard Reutner-Fischer
We were relying on FE_DIVBYZERO being turned off when printing "%f", +-.0 Avoid the whole issue by looking at the sign-bit (in a rough approximation). Note that we do not handle gracefully: printf ("\n%llf\n", -0.0); printf ("\n%llf\n", 0.0); nor %Lf for both when NOT cast to long double. Avoiding an FPE due to broken numbers like these does not make sense to me. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

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.
