Binutils with MCST patches
582511be69
This patch applies the same starvation avoidance improvements of the previous patch to the Linux gdbserver side. Without this, the test added by the following commit (gdb.threads/non-stop-fair-events.exp) always fails with time outs. gdb/gdbserver/ 2015-01-09 Pedro Alves <palves@redhat.com> * linux-low.c (step_over_bkpt): Move higher up in the file. (handle_extended_wait): Don't store the stop_pc here. (get_stop_pc): Adjust comments and rename to ... (check_stopped_by_breakpoint): ... this. Record whether the LWP stopped for a software breakpoint or hardware breakpoint. (thread_still_has_status_pending_p): New function. (status_pending_p_callback): Use thread_still_has_status_pending_p. If the event is no longer interesting, resume the LWP. (handle_tracepoints): Add assert. (maybe_move_out_of_jump_pad): Remove cancel_breakpoints call. (wstatus_maybe_breakpoint): New function. (cancel_breakpoint): Delete function. (check_stopped_by_watchpoint): New function, factored out from linux_low_filter_event. (lp_status_maybe_breakpoint): Delete function. (linux_low_filter_event): Remove filter_ptid argument. Leave thread group exits pending here. Store the LWP's stop PC. Always leave events pending. (linux_wait_for_event_filtered): Pull all events out of the kernel, and leave them all pending. (count_events_callback, select_event_lwp_callback): Consider all events. (cancel_breakpoints_callback, linux_cancel_breakpoints): Delete. (select_event_lwp): Only give preference to the stepping LWP in all-stop mode. Adjust comments. (ignore_event): New function. (linux_wait_1): Delete 'retry' label. Use ignore_event. Remove references to cancel_breakpoints. Adjust to renames. Also give equal priority to all LWPs that have had events in non-stop mode. If reporting a software breakpoint event, unadjust the LWP's PC. (linux_wait): If linux_wait_1 returned an ignored event, retry. (stuck_in_jump_pad_callback, move_out_of_jump_pad_callback): Adjust. (linux_resume_one_lwp): Store the LWP's PC. Adjust. (resume_status_pending_p): Use thread_still_has_status_pending_p. (linux_stopped_by_watchpoint): Adjust. (linux_target_ops): Remove reference to linux_cancel_breakpoints. * linux-low.h (enum lwp_stop_reason): New. (struct lwp_info) <stop_pc>: Adjust comment. <stopped_by_watchpoint>: Delete field. <stop_reason>: New field. * linux-x86-low.c (x86_linux_prepare_to_resume): Adjust. * mem-break.c (software_breakpoint_inserted_here) (hardware_breakpoint_inserted_here): New function. * mem-break.h (software_breakpoint_inserted_here) (hardware_breakpoint_inserted_here): Declare. * target.h (struct target_ops) <cancel_breakpoints>: Remove field. (cancel_breakpoints): Delete. * tracepoint.c (clear_installed_tracepoints, stop_tracing) (upload_fast_traceframes): Remove references to cancel_breakpoints. |

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.
