(pthread_attr_setguardsize): Export. (pthread_attr_setstack): Export. (pthread_attr_setstackaddr): Export. * init.cc (dll_entry): Remove wow64_test_stack_marker. Check for unusual stack address by testing stack addresses from current TEB. Check validity of _my_tls by testing if it's within the stack as given in current TEB. * miscfuncs.cc (struct thread_wrapper_arg): New structure used to push all required information to thread_wrapper function. (thread_wrapper): Wrapper function for actual thread function. If an application stack has been given, change %ebp and %esp so that the thread function runs on that stack. If the thread has been created by CygwinCreateThread, set up the POSIX guard pages if necessary. (CygwinCreateThread): New function. * miscfuncs.h (CygwinCreateThread): Declare. * ntdll.h (struct _TEB): Define all members up to Peb. * posix.sgml (std-susv4): Move pthread_attr_getguardsize, pthread_attr_setguardsize and pthread_attr_setstack here. (std-deprec): Add pthread_attr_setstackaddr. * sysconf.cc (sca): Set _SC_THREAD_ATTR_STACKADDR to _POSIX_THREAD_ATTR_STACKADDR. * thread.cc (pthread::precreate): Copy pthread_attr stackaddr and guardsize members. (pthread::create): Call CygwinCreateThread. (pthread_attr::pthread_attr): Initialize guardsize. (pthread_attr_setstack): New function. (pthread_attr_setstackaddr): New function. (pthread_attr_setguardsize): New function. (pthread_attr_getguardsize): New function. (pthread_getattr_np): Copy attr.guardsize. * thread.h (pthread_attr): Add member guardsize. * include/pthread.h (pthread_attr_getguardsize): Declare. (pthread_attr_setguardsize): Declare. * include/cygwin/version.h: Bump API minor number.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
