* [ARM] Make _kill() a noreturn function.Christophe Lyon2018-10-083-9/+14
| | | | | | | | | | | | | | AngelSWI_Reason_ReportException does not return accoring to the ARM documentation, so it is valid to mark _kill() as noreturn. This way, the compiler does not warn about _exit() returning a value despite being noreturn. 2018-10-01 Christophe Lyon <christophe.lyon@linaro.org> * libgloss/arm/_exit.c (_exit): Declare _kill() as noreturn. * libgloss/arm/_exit.c (_kill): Likewise. Remove the return statements. * newlib/libc/sys/arm/syscalls.c (_kill): Likewise..

* Update Arm copyright notices in new math filesWilco Dijkstra2018-09-2826-47/+79
| | | | | | | | While working on the strstr patch I noticed several copyright headers of the new math functions are missing closing quotes after ``AS IS. I've added these. Also update spellings of Arm Ltd in a few places (but still use ARM LTD in upper case portion). Finally add SPDX identifiers to make everything consistent.
* Update Arm entry in COPYING.NEWLIB.Jeff Johnston2018-09-251-2/+2
| | | | | | | - per Wilco Dijkstra's patch - update Arm copyright notice to not exclude AArch64 and the various generic contributions made (like the new math functions). Also update the date and change spelling to Arm Ltd.

* Committed, CRIS port: fix fallout from time_t defaulting to 64 bits, part 2Hans-Peter Nilsson2018-09-131-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | It's been a while... I see the CRIS port broke with the time_t-default-to-64-bit change, observable by a few test-cases in the gcc fortran(!) tests failing, regressing when trying a recent newlib. This is a two-part belt-and-suspenders change: adjust the CRIS port gettimeofday syscall (the only one in newlib/CRIS passing a time_t or struct timeval) to handle a userspace 64-bit time_t and secondly default time_t to 32-bit long anyway. I considered making the local "kernel_timeval" copy in _gettimeofday conditional on (userspace) time_t being 64 bits, but thought it not worth bothering with the few move insns. The effect of a 64-bit time_t is however observable as longer simulation time when running the gcc testsuite and as bigger binaries without any actual upside from the larger time_t size, so I thought better make the default for this port go back to being a "long" again. Tested by running the gcc testsuite over the three combinations of two parts of the patch and observing the expected changes.

* Include sys/syslimits.h in limits.hKeith Packard2018-09-061-0/+1
| | | | | | | | | | This makes sure any system-defined limits are specified before the defaults are checked.

* Improve strstr performance of short needlesWilco Dijkstra2018-09-051-10/+65
| | | | | | | | Improve strstr performance for the common case of short needles. For a single character strchr is best, for 2-4 characters a small loop is fastest. For these the speedup over the Two-Way algorithm is ~10 times on large strings. Newlib builds, the new code passes GLIBC testsuite. OK for commit?

* Avoid ARM SWI Seek when querying file positionAndy Koppe2018-09-031-2/+9
| | | | | | | | | | | | | | | | | | | Issuing an ARM semi-hosting Seek command when just querying file position with SEEK_CUR and offset zero is unnecessary, because unlike the lseek() Unix system call the Seek command does not actually return the file position. For that reason, syscalls.c for ARM keeps track of file position in the 'poslog', so we can just return that. Moreover, since the Seek command only accepts an absolute file position, SEEK_CUR operations are implemented by adding the relative offset to the position in the poslog. If the host implements non-binary files with implicit carriage return characters but doesn't discount those implicit CRs when implementing Seek (by just mapping straight to Windows file operations), this actually ended up wrongly changing file position when using SEEK_CUR with offset zero or functions like ftell() or fgetpos() that are based on that. Also, use off_t rather than int for the poslog.
* Cygwin: console: Print Unicode REPLACEMENT CHARACTER for invalid input charsCorinna Vinschen2018-09-011-4/+3
| | | | | | | | So far we printed a half filled square (0x2592) if the input char is invalid, but using REPLACEMENT CHARACTER (0xfffd) is apparently the way to go. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Cygwin: fix Win32 path ".." backtrackingCorinna Vinschen2018-09-012-5/+29
| | | | | | | | | | | | | Commit 35998fc2fa6cbb7d761f6d88346246bd3627552b fixed the buffer underun in win32 path normalization, but introduced a new bug: A wrong assumption led to the inability to backtrack the path outside of the current working directory in case of relative paths. This patch fixes this problem, together with a minor problem if the CWD is on a network share: The result erroneously started with tripple backslash if the src path starts with a single backslash.

* RTEMS: Add kvaddr_t and ksize_tSebastian Huber2018-08-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | These types were introduced by FreeBSD commit: "Make struct xinpcb and friends word-size independent. Replace size_t members with ksize_t (uint64_t) and pointer members (never used as pointers in userspace, but instead as unique idenitifiers) with kvaddr_t (uint64_t). This makes the structs identical between 32-bit and 64-bit ABIs. On 64-bit bit systems, the ABI is maintained. On 32-bit systems, this is an ABI breaking change. The ABI of most of these structs was previously broken in r315662. This also imposes a small API change on userspace consumers who must handle kernel pointers becoming virtual addresses. PR: 228301 (exp-run by antoine) Reviewed by: jtl, kib, rwatson (various versions) Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D15386" In RTEMS, there is no user/kernel space separation.
