This patch reorganizes the code that implements follow-fork and detach-on-fork in preparation for implementation of those features for the extended-remote target. The function linux-nat.c:linux_child_follow_fork contained target-independent code mixed in with target-dependent code. The target-independent pieces need to be accessible for the host-side implementation of follow-fork for extended-remote Linux targets. The changes are fairly mechanical. A new routine, follow_fork_inferior, is implemented in infrun.c, containing those parts of linux_child_follow_fork that manage inferiors and the inferior list. The parts of linux_child_follow_fork that deal with LWPs and target-specifics were left in-place. Although the order of some operations was changed, the resulting functionality was not. Modifications were made to the other native target follow-fork functions, inf_ttrace_follow_fork and inf_ptrace_follow_fork, that should allow them to work with follow_fork_inferior. Some other adjustments were necessary in inf-ttrace.c. The changes to inf-ttrace.c and inf-ptrace.c were not tested. gdb/ChangeLog: * inf-ptrace.c (inf_ptrace_follow_fork): Remove target-independent code so as to work with follow_fork_inferior. * inf-ttrace.c (inf_ttrace_follow_fork): Ditto. (inf_ttrace_create_inferior): Remove reference to inf_ttrace_vfork_ppid. (inf_ttrace_attach): Ditto. (inf_ttrace_detach): Ditto. (inf_ttrace_kill): Use current_inferior instead of inf_ttrace_vfork_ppid. (inf_ttrace_wait): Eliminate use of inf_ttrace_vfork_ppid, report TARGET_WAITKIND_VFORK_DONE event, delete HACK that switched the inferior away from the parent. * infrun.c (follow_fork): Call follow_fork_inferior instead of target_follow_fork. (follow_fork_inferior): New function. (follow_inferior_reset_breakpoints): Make function static. * infrun.h (follow_inferior_reset_breakpoints): Remove declaration. * linux-nat.c (linux_child_follow_fork): Move target-independent code to infrun.c:follow_fork_inferior.
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.
