* Cygwin: improve O_TMPFILE handlingCorinna Vinschen2018-02-143-13/+29
| | | | | | | | | | | | | | | | Windows does not remove FILE_ATTRIBUTE_TEMPORARY by itself after a file has been closed. It's just some attribute which can be set or removed at will, despite its purpose. Apparently there are tools out there which use FILE_ATTRIBUTE_TEMPORARY accidentally or wrongly, even Microsoft's own tools are affected. In the end, the filesystem is potentially full of files with this attribute set. Implement O_TMPFILE files with FILE_ATTRIBUTE_TEMPORARY and FILE_ATTRIBUTE_HIDDEN set. This combination is pretty unlikely. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: Fix x86 compiler warningCorinna Vinschen2018-02-071-1/+1
| | | | | | | | | The previous patch introduced a compiler warning on x86. Given time_t is only 4 bytes on x86 we get a long vs. unsigned long comparison in timeval_to_ms. Fix it by careful casting. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: bindresvport: Try hard to find unused portCorinna Vinschen2018-02-052-8/+84
| | | | | | | | | | Workaround the problem that bind doesn't fail with EADDRINUSE if a socket with the same local address is still in TIME_WAIT. Use IP Helper functions to check if such a socket exist and don't even try this port, if so. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Cygwin: bindresvport: check correctness of address familyCorinna Vinschen2018-02-051-1/+10
| | | | | | | | | | | | Assuming the address parameter is non-NULL, the test in cygwin_bindresvport_sa only tests if the address family is supported at all, which is insufficient. Check if the incoming address family matches the socket address family and for being AF_INET in cygwin_bindresvport since the latter doesn't support any other family.

* Disable powf/log2?f/exp2?f optimization for single-precision Arm FPUThomas Preudhomme2018-01-251-1/+3
| | | | | | | | | | | | | | | | New optimized powf, logf, log2f, expf and exp2f yield worse performance on Arm targets with only single precision instructions because the double precision arithmetic is then implemented via softfloat routines. This patch uses the old implementation when double precision instructions are not available on Arm targets. Testing: Built newlib with GCC's rmprofile Arm multilibs and compared before/after -> only the above functions are changed and calls to them (name change from logf to __ieee754_logf and similar). Testing the changed function on a panel of values yields the same result before the original patches to improve them and after this one. Double checking the performance by looping the same panel of values being tested on Arm Cortex-M4 does show the performance regression is fixed.
* Define internal function mythreadname() -- revisedMark Geisert2018-01-245-4/+21
| | | | | | This new function returns the name of the calling thread; works for both cygthreads and pthreads. All calls to cygthread::name(/*void*/) replaced by calls to mythreadname(/*void*/).
