(child_info::rd_proc_pipe): Declare new field. (child_info::wr_proc_pipe): Ditto. (child_info::prefork): Declare new function, derived from previous pinfo version. * dcrt0.cc (child_info_fork::handle_fork): Close previous wr_proc_pipe when appropriate and assign new one from passed-in child_info block. (child_info_spawn::handle_spawn): Assign our wr_proc_pipe handle from passed-in child_info block. * fork.cc (child_info::prefork): Define new function. (frok::child): Clear rd_proc_pipe and wr_proc_pipe so they will not be closed by the child_info destructor. (frok::parent): Use child_info prefork handling, outside of retry loop. Set rd_proc_pipe in child's pinfo after successful CreateProcess. Eliminate postfork call. * globals.cc (my_wr_proc_pipe): Define/declare new variable. * pinfo.cc (pinfo::pending_rd_proc_pipe): Delete. (pinfo::pending_wr_proc_pipe): Ditto. (pinfo::prefork): Ditto. (pinfo::postfork): Ditto. (pinfo::postexec): Ditto. (pinfo::wait): Assume that rd_proc_pipe is set up correctly prior to call. (_pinfo::alert_parent): Replace "wr_proc_pipe" with "my_wr_proc_pipe". * pinfo.h (_pinfo::_wr_proc_pipe): Delete declaration. (_pinfo::set_rd_proc_pipe): Define new function. (pinfo::pending_rd_proc_pipe): Delete declaration. (pinfo::pending_wr_proc_pipe): Ditto. (pinfo::prefork): Ditto. (pinfo::postfork): Ditto. (pinfo::postexec): Ditto. (pinfo::wr_proc_pipe): Ditto. * sigproc.cc (child_info::child_info): Clear rd_proc_pipe and wr_proc_pipe. (child_info::cleanup): Close rd_proc_pipe and wr_proc_pipe if necessary. (child_info_fork::child_info_fork): Set forker_finished to NULL by default. (child_info_spawn::child_info_spawn): Use my_wr_proc_pipe rather than myself->wr_proc_pipe. (child_info::sync): Ditto. (child_info_spawn::cleanup): Call child_info::cleanup. * spawn.cc (child_info_spawn::worker): Remove call to myself.prefork(). Set wr_proc_pipe when execing or set up new rd_proc_pipe/wr_proc_pipe via child_info::prefork when spawning. Remove call to pinfo::postexec. Set rd_proc_pipe in child pinfo when spawning. Use my_wr_proc_pipe rather than myself->wr_proc_pipe. Remove call to postfork.
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.
