Previously, sigfe had a bug that the signal handler destroys fpu state. This is caused by fninit instruction in sigdelayed. With this patch, saving/restoring the FPU/SIMD state is done using fxsave/fxrstor or xsave/xrstor rather than fnstcw/fldcw, stmxcsr/ldmxcsr and push/pop xmm0-xmm15. Since xsave/xrstor is used, not only x87/MMX/SSE states but also AVX/AVX2/AVX-512 states can be maintained unlike before. Addresses: https://cygwin.com/pipermail/cygwin/2024-October/256503.html Fixes: ed89fbc3ff11 ("* gendef (sigdelayed (x86_64)): Save and restore FPU control word.")

What's new:
|
|
-----------
|
|
|
|
- New API call: getlocalename_l.
|
|
|
|
- New API calls: fdclosedir, posix_getdents.
|
|
|
|
- New API call: setproctitle.
|
|
|
|
- New API call: timespec_get.
|
|
|
|
- Add FS_IOC_[GS]ETFLAGS FS_PINNED_FL and FS_UNPINNED_FL flags to handle
|
|
Windows attributes FILE_ATTRIBUTE_PINNED and FILE_ATTRIBUTE_UNPINNED.
|
|
Add matching 'p' and 'u' mode bits in chattr(1) and lsattr(1).
|
|
|
|
|
|
What changed:
|
|
-------------
|
|
|
|
- ps -f now prints the commandline rather than the full path to the
|
|
executable.
|
|
|
|
- Drop support for NT4 and Samba < 3.0.22.
|
|
|
|
- Now that SMBv1 is ultimately deprecated and not installed by default
|
|
on latest Windows versions, use Network Discovery (i. e. WSD, "Web
|
|
Service Discovery") for enumerating network servers in //, just like
|
|
Windows Explorer.
|
|
|
|
- If "server" is given as FQDN, and if "server" is an NFS server,
|
|
ls //server now also enumerates NFS shares. If "server" is given
|
|
as a flat name, only SMB shares are enumerated.
|
|
|
|
- Expose //tsclient (Microsoft Terminal Services) shares as well as
|
|
//wsl$ (Plan 9 Network Provider) shares, i. e., WSL installation
|
|
root dirs.
|
|
|
|
- Redesign pipe handling to minimize toggling blocking mode.
|
|
The query_hdl stuff is no longer needed in new implementation.
|
|
|
|
- Now using AVX/AVX2/AVX-512 instructions in signal handler does not
|
|
break their context.
