* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-3/+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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch should address all of the review comments. Modifed change log: Newlib: * libc/include/sys/features.h (_POSIX_BARRIERS): Define for Cygwin. * libc/include/sys/types.h (pthread_barrier_t) (pthread_barrierattr_t): Do not define for Cygwin. Cygwin: * common.din (pthread_barrierattr_init) (pthread_barrierattr_setpshared, pthread_barrierattr_getpshared) (pthread_barrierattr_destroy, pthread_barrier_init) (pthread_barrier_destroy, pthread_barrier_wait): Export. * include/cygwin/types.h (pthread_barrierattr_t) (pthread_barrier_t): Declare. * include/pthread.h (PTHREAD_BARRIER_SERIAL_THREAD) (pthread_barrierattr_init, pthread_barrierattr_setpshared) (pthread_barrierattr_getpshared, pthread_barrierattr_destroy) (pthread_barrier_init, pthread_barrier_destroy) (pthread_barrier_wait): Declare. * thread.h (PTHREAD_BARRIER_MAGIC) (PTHREAD_BARRIERATTR_MAGIC): Define.

* Always allocate main thread stack from pthread stack area on x86_64.Corinna Vinschen2015-12-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | * dcrt0.cc: Semi-revert commit 12743c2d5d2721f3a80b4d7671a349be03c1f520. (dll_crt0_0): Drop setting wow64_needs_stack_adjustment on 64 bit. (_dll_crt0): Split out 64 bit code again and always create new main thread stack, unless forked off from the non main thread in the parent. Call create_new_main_thread_stack with parent stack commitsize if started from the parent's main thread. Only call child_info_fork::alloc_stack for the latter case on 64 bit. Slightly rearrange moving rsp and rbp to new stack and document how. Revert 32 bit wow64 handling to its former self. * miscfunc.cc (create_new_main_thread_stack): Take a commitsize parameter and use it if it's not 0. Don't set _main_tls here, it's done in the caller _dll_crt0 anyway. Return stackbase - 16 bytes, rather than stacklimit (which was very wrong anyway). * miscfuncs.h (create_new_main_thread_stack): Accommodate declaration to aforementioned change. * wincap.h (wincaps::has_3264_stack_broken): Remove element. * wincap.cc: Ditto, throughout. * wow64.cc: Semi-revert to pre-12743c2d5d2721f3a80b4d7671a349be03c1f520 but keep architecture-agnostic type changes intact. Fix formatting. * wow64.h: Revert to pre-12743c2d5d2721f3a80b4d7671a349be03c1f520. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
