This patch fixes a regression introduced by : https://sourceware.org/ml/gdb-patches/2015-10/msg00369.html Tests : gdb.trace/trace-break.exp and gdb.trace/trace-mt.exp would fail on x86 with gdbserver-{native,extended}. Before this patch, the breakpoint kind set by GDB with a Z packet and the one set in the case of a tracepoint would be inconsistent on targets that did not implement breakpoint_kind_from_pc. On x86 for example a breakpoint set by GDB would have a kind of 1 but a breakpoint set by a tracepoint would have a kind of 0. This created a missmatch when trying to insert a tracepoint and a breakpoint at the same location. One of the two breakpoints would be removed with debug message : "Inconsistent breakpoint kind". This patch fixes the issue by changing the default 0 breakpoint kind to be the size of the breakpoint according to sw_breakpoint_from_kind. The default breakpoint kind must be the breakpoint length to keep consistency between breakpoints set via GDB and the ones set internally by GDBServer. No regression on Ubuntu 14.04 x86-64 with gdbserver-{native-extended} gdb/gdbserver/ChangeLog: * linux-low.c (default_breakpoint_kind_from_pc): New function. (linux_breakpoint_kind_from_pc): Use default_breakpoint_kind_from_pc for the default breakpoint kind.
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.
