2022-08-05Cygwin: Reorganize cygwin source dirCorinna Vinschen1-56/+0
Create subdirs and move files accordingly: - DevDocs: doc files - fhandler: fhandler sources, split fhandler.cc into base.cc and null.cc - local_includes: local include files - scripts: scripts called during build - sec: security sources Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2022-08-04Cygwin: create sparse errmap arrayCorinna Vinschen1-7/+0
To avoid linear searches for error codes, autogenerate errmap as simple array of errno values indexed by Windows error codes. Restrict to the first 9000 Windows error codes, we don't care for most of them anyway. Define errmap in its own file errmap.h to clean up errno.cc. Change geterrno_from_win_error accordingly. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2022-07-13Add _REENT_ERRNO(ptr)Matt Joyce1-2/+2
Add a _REENT_ERRNO() macro to encapsulate the access to the _errno member of struct reent. This will help to replace the structure member with a thread-local storage object in a follow up patch. Replace uses of __errno_r() with _REENT_ERRNO(). Keep __errno_r() macro for potential users outside of Newlib.
2022-06-06Cygwin: remove most occurrences of __stdcall and __cdeclKen Brown1-1/+1
These have no effect on x86_64. Retain a few occurrences of __cdecl in files imported from other sources. Also retain all occurrences of WINAPI, even though the latter is simply a macro that expands to __stdcall. Most of these occurrences are associated with Windows API functions, and removing them might make the code confusing instead of simpler.
2022-05-29Cygwin: remove regparm.hKen Brown1-6/+5
This file defines the macros __reg1, __reg2, and __reg3, which are defined to be empty on 64-bit Cygwin. Remove all occurrences of these macros.
2018-02-20Cygwin: set/getsockopt: Move implementation into fhandler_socket classCorinna Vinschen1-0/+1
This requires to export find_winsock_errno from net.cc. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2018-02-20Cygwin: clean error mappingCorinna Vinschen1-0/+10
- Move definition of windows to POSIX error mapping struct into cygerrno.h - Move declaration of winsock errno functions to cygerrno.h - Input to error mapping functions is DWORD Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2017-07-19Revert "errno: Stop using _impure_ptr->_errno completely"Corinna Vinschen1-2/+2
This reverts commit 44b1746a41921533d27aca414a9188314cb725b6. Bad idea. _impure_ptr->_errno is used by newlib Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2017-03-10errno: Stop using _impure_ptr->_errno completelyCorinna Vinschen1-2/+2
We use errno AKA _REENT->_errno since the last century and only set _impure_ptr->_errno for backward compat. Stop that. Also, remove the last check for _impure_ptr->_errno in Cygwin code. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2016-06-23Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen1-3/+0
Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
