Remove the to_supports_btrace target method and instead rely on detecting errors when trying to enable recording. This will also provide a suitable error message explaining why recording is not possible. For remote debugging, gdbserver will now always advertise branch tracing related packets. When talking to an older GDB, this will cause GDB to try to enable branch tracing and gdbserver to report a suitable error message every time. An older gdbserver will not advertise branch tracing related packets if the one-time check failed, so a newer GDB with this patch will fail to enable branch tracing at remote_enable_btrace() rather than at btrace_enable(). The error message is the same in both cases so there should be no user-visible change. gdb/ * btrace.c (btrace_enable): Remove target_supports_btrace call. * nat/linux-btrace.c (perf_event_pt_event_type): Move. (kernel_supports_bts, kernel_supports_pt, linux_supports_bts) (linux_supports_pt, linux_supports_btrace): Remove. (linux_enable_bts): Call cpu_supports_bts. * nat/linux-btrace.h (linux_supports_btrace): Remove. * remote.c (remote_supports_btrace): Remove. (init_remote_ops): Remove remote_supports_btrace. * target-delegates.c: Regenerated. * target.c (target_supports_btrace): Remove. * target.h (target_ops) <to_supports_btrace>: Remove (target_supports_btrace): Remove. * x86-linux-nat.c (x86_linux_create_target): Remove linux_supports_btrace. gdbserver/ * linux-low.c (linux_target_ops): Remove linux_supports_btrace. * nto-low.c (nto_target_ops): Remove NULL for supports_btrace. * spu-low.c (spu_target_ops): Likewise. * win32-low.c (win32_target_ops): Likewise. * server.c (supported_btrace_packets): Report packets unconditionally. * target.h (target_ops) <supports_btrace>: Remove. (target_supports_btrace): Remove. |

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.
