* get_nprocs: Only return explictly set cache values (BZ #16996)Meador Inge2014-06-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of __get_nprocs uses a stactic variable to cache the value of the current number of processors. The caching breaks when 'time (NULL) == 0': $ cat nproc.c #include <stdio.h> #include <time.h> #include <sys/time.h> int main(int argc, char *argv[]) { time_t t; struct timeval tv = {0, 0}; printf("settimeofday({0, 0}, NULL) = %d\n", settimeofday(&tv, NULL)); t = time(NULL); printf("Time: %d, CPUs: %d\n", (unsigned int)t, get_nprocs()); return 0; } $ gcc -O3 nproc.c $ ./a.out settimeofday({0, 0}, NULL) = -1 Time: 1401311578, CPUs: 4 $ sudo ./a.out settimeofday({0, 0}, NULL) = 0 Time: 0, CPUs: 0 The problem is with the condition used to check whether a cached value should be returned or not: static int cached_result; static time_t timestamp; time_t now = time (NULL); time_t prev = timestamp; atomic_read_barrier (); if (now == prev) return cached_result; This patch fixes the problem by ensuring that 'cached_result' has been set at least once before returning it.

* hppa: Remove lowlevellock.c.Bernard Ogden2014-06-091-126/+0
| | | | | | The hppa port has no need of a custom lowlevellock.c, it should use the generic version which is updated and correct. This similarly fixes bug 15119 for hppa.

* aarch64: Consolidate NPTL/non versions of vforkRichard Henderson2014-06-033-44/+74
| | | | | At the same time, incorporate the 0 -> 0x80000000 mapping of the pid expected by raise.c.
* aarch64: Consolidate NPTL/non versions of cloneRichard Henderson2014-06-032-53/+24
| | | | | | At the same time, rely on non-clobbered registers across syscall so that we eliminate the stack frame that we previously ignored in the unwind info.

| | | | | Forgotten in ca3cfa40c16ef34c74951a07a57cfcbcd58898b1 where the error branch was moved from PSEUDO_RET.

* aarch64: Rely on syscalls preserving registersRichard Henderson2014-05-291-24/+12
| | | | | | | | In several cases we've had asm routines rely on syscalls not clobbering call-clobbered registers, and that's now deemed ABI. So take advantage of this in the INLINE_SYSCALL path as well. Shrinks libc.so by about 1k.

* Avoid stat/fstat in statvfs/fstatvfs (BZ #15132)Eric Wong2014-05-295-27/+18
| | | | | Delay the use of stat/fstat until stat data is required. When the kernel returns ST_VALID, stat data is not used by __internal_statvfs.

* arm,aarch64: Remove SINGLE_THREAD_P_PICRichard Henderson2014-05-252-2/+0
| | | | | | | | | | This macro was removed by 2005-11-16 Daniel Jacobowitz <dan@codesourcery.com> but not applied to the (still separate) eabi port so necro'd when the eabi port superceded the old abi. It was thence copied into the new AArch64 port.
* aarch64: Tidy syscall error checkRichard Henderson2014-05-252-10/+13
| | | | | Move the error branch from the PSEUDO_RET macro to the PSEUDO macro. This is in line with other architectures, and will enable further improvments.
