2020-02-20newlib/libc/include/devctl.h: Add extern "C" wrapperJoel Sherrill1-0/+8
Adding this was necessary to allow posix_devctl() from C++.

2019-12-13Fix setjmp/longjmp for the moxie port.Anthony Green1-1/+1
These functions needs to save and restore the stack frame, because that's where the return address is stored.

2019-11-04Move timeval macros to <sys/time.h>Sebastian Huber2-32/+31
In FreeBSD, NetBSD, and OpenBSD these macros are defined in <sys/time.h>.
2019-11-04Synchronize <sys/time.h> with FreeBSDSebastian Huber1-0/+27
This change is based on the FreeBSD commit: Author: asomers <asomers@FreeBSD.org> Date: Mon Jul 30 15:46:40 2018 +0000 Make timespecadd(3) and friends public The timespecadd(3) family of macros were imported from NetBSD back in r35029. However, they were initially guarded by #ifdef _KERNEL. In the meantime, we have grown at least 28 syscalls that use timespecs in some way, leading many programs both inside and outside of the base system to redefine those macros. It's better just to make the definitions public. Our kernel currently defines two-argument versions of timespecadd and timespecsub. NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define three-argument versions. Solaris also defines a three-argument version, but only in its kernel. This revision changes our definition to match the common three-argument version. Bump _FreeBSD_version due to the breaking KPI change. Discussed with: cem, jilles, ian, bde Differential Revision: https://reviews.freebsd.org/D14725

2019-10-07Allow verifying _REENT_CHECK macros memory allocationJeff Johnston1-3/+3
- change sys/reent.h to replace _REENT_CHECK_DEBUG with _REENT_CHECK_VERIFY which when set asserts that any memory allocated is non-NULL and calls __assert_func directly - add new --enable-newlib-reent-check-verify configure option - add support for configure.host to specify default for newlib_reent_check_verify - add _REENT_CHECK_VERIFY macro support to acconfig.h and newlib.hin

2019-08-09Add default implementation of fenv.h and all methodsJoel Sherrill2-0/+155
The default implementation of the fenv.h methods return -EOPNOTSUP. Some of these have implementations appropriate for soft-float. The intention of the new fenv.h is that it be portable and that architectures provide their own implementation of sys/fenv.h.

2019-06-27or1k: Avoid write outside setjmp buf & shrink bufMartin Erik Werner1-1/+4
Update the offsets used to save registers into the stejmp jmp_buf structure in order to: * Avoid writing the supervision register outside the buffer and thus clobbering something on the stack. Previously the supervision register was written at offset 124 while the buffer was of length 124. * Shrink the jmp_buf down to the size actually needed, by avoiding holes at the locations of omitted registers.
2019-06-25Support calculation of pointer size for __int20__ type in _intsup.hJozef Lawrynowicz1-0/+4
GCC r272640 modifies the MSP430 target to use "__int20__" for PTRDIFF_TYPE (and therefore INTPTR_TYPE) instead of "__int20". To support the calculation of pointer size in newlib/libc/include/sys/_intsup.h, definitions for __int20__ need to be added.
2019-06-24Cygwin: Implement sched_[gs]etaffinity()Mark Geisert1-0/+23
This patch set implements the Linux syscalls sched_getaffinity, sched_setaffinity, pthread_getaffinity_np, and pthread_setaffinity_np. Linux has a straightforward view of the cpu sets used in affinity masks. They are simply long (1024-bit) bit masks. This code emulates that view while internally dealing with Windows' distribution of available CPUs among processor groups.
2019-06-14Rename <xlocale.h> back to <sys/_locale.h>Corinna Vinschen11-13/+13
libX11 provides <X11/Xlocale.h>. The build of libX11 itself adds include/X11 to the compiler's include path. This results in a name collision with /usr/include/xlocale.h on case-insensitive filesystems. Commit 90e35b1eb3df renamed sys/_locale.h to xlocale.h in March 2017 under the assumption that we should provide the locale_t type in the same file as on Linux, FreeBSD, and Darwin. A few weeks later (June 2017), glibc removed the xlocale.h file in favor of bits/types/locale_t.h, which shouldn't be included directly anyway. For reference and the reasoning, see https://sourceware.org/git/?p=glibc.git;a=commit;h=f0be25b6336d Given the above, revert 90e35b1eb3df4070e68afc5e7060665214d586be and fix additional usage of xlocale.h.

2019-06-07sys/sys: further adoption of SPDX licensing ID tags.pfg1-0/+2
Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.
2019-06-03Fix <sys/_types.h> issues with <stddef.h>Sebastian Huber2-5/+3
A commit from 2016 tried to address this GCC provided <stddef.h> issue #if (defined (__FreeBSD__) && (__FreeBSD__ >= 5)) \ || defined(__DragonFly__) \ || defined(__FreeBSD_kernel__) /* __size_t is a typedef on FreeBSD 5, must not trash it. */ #elif defined (__VMS__) /* __size_t is also a typedef on VMS. */ #else #define __size_t #endif with an include of <stddef.h> before <sys/_types.h> in <sys/types.h>.

2019-06-03Avoid cyclic header dependenciesSebastian Huber2-5/+5
RTEMS uses a considerable part of FreeBSD kernel and user space sources. These sources are compiled with a __FreeBSD__ define. On 2018-06-26 Gerald Pfeifer changed the GCC provided <stddef.h> so that it includes <sys/_types.h> if __FreeBSD__ is defined. The Newlib <sys/_types.h> included <sys/lock.h> which includes <sys/cdefs.h> on RTEMS which includes <stddef.h>. To get rid of this cyclic dependency move the optional _flock_t definition to <sys/reent.h>. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

2019-01-15AMD GCN Port contributed by Andrew Stubbs <ams@codesourcery.com>Jeff Johnston2-0/+8
Add support for the AMD GCN GPU architecture. This is primarily intended for use with OpenMP and OpenACC offloading. It can also be used for stand-alone programs, but this is intended mostly for testing the compiler and is not expected to be useful in general. The GPU architecture is highly parallel, and therefore Newlib must be configured to use dynamic re-entrancy, and thread-safe malloc. The only I/O available is a via a shared-memory interface provided by libgomp and the gcn-run tool included with GCC. At this time this is limited to stdout, argc/argv, and the return code.

2018-12-04Ensure that all values of ns, us and ms workimp1-7/+52
for {n,u,m}stosbt Integer overflows and wrong constants limited the accuracy of these functions and created situatiosn where sbttoXs(Xstosbt(Y)) != Y. This was especailly true in the ns case where we had millions of values that were wrong. Instead, used fixed constants because there's no way to say ceil(X) for integer math. Document what these crazy constants are. Also, use a shift one fewer left to avoid integer overflow causing incorrect results, and adjust the equasion accordingly. Document this. Allow times >= 1s to be well defined for these conversion functions (at least the Xstosbt). There's too many users in the tree that they work for >= 1s. This fixes a failure on boot to program firmware on the mlx4 NIC. There was a msleep(1000) in the code. Prior to my recent rounding changes, msleep(1000) worked, but msleep(1001) did not because the old code rounded to just below 2^64 and the new code rounds to just above it (overflowing, causing the msleep(1000) to really sleep 1ms). A test program to test all cases will be committed shortly. The test exaustively tries every value (thanks to bde for the test).

2018-12-04When converting ns,us,ms to sbt, return the ceil()imp1-3/+7
of the result rather than the floor(). Returning the floor means that sbttoX(Xtosbt(y)) != y for almost all values of y. In practice, this results in a difference of at most 1 in the lsb of the sbintime_t. This difference is meaningless for all current users of these functions, but is important for the newly introduced sysctl conversion routines which implicitly rely on the transformation being idempotent.

2018-12-04Add inline functions to convert between sbintime_tian1-7/+52
and decimal time units. Use them in some existing code that is vulnerable to roundoff errors. The existing constant SBT_1NS is a honeypot, luring unsuspecting folks into writing code such as long_timeout_ns*SBT_1NS to generate the argument for a sleep call. The actual value of 1ns in sbt units is ~4.3, leading to a large roundoff error giving a shorter sleep than expected when multiplying by the trucated value of 4 in SBT_1NS. (The evil honeypot aspect becomes clear after you waste a whole day figuring out why your sleeps return early.)
