This patch replaces VEC(static_tracepoint_marker_p) with std::vector, and does some c++ification around that. I thought a new overload of hex2str was useful, so I added it as well as corresponding unit tests. I also added an overload of ui_out::field_string that takes an std::string directly. gdb/ChangeLog: * tracepoint.h (struct static_tracepoint_marker): Initialize fields, define default constructor, move constructor and move assignment, disable the rest. <str_id, extra>: Make std::string. (release_static_tracepoint_marker): Remove. (free_current_marker): Remove. * tracepoint.c (free_current_marker): Remove. (parse_static_tracepoint_marker_definition): Adjust to std::string, use new hex2str overload. (release_static_tracepoint_marker): Remove. (print_one_static_tracepoint_marker): Get marker by reference and adjust to std::string. (info_static_tracepoint_markers_command): Adjust to std::vector changes * target.h (static_tracepoint_marker_p): Remove typedef. (DEF_VEC_P(static_tracepoint_marker_p)): Remove. (struct target_ops) <to_static_tracepoint_marker_at>: Return bool. <to_static_tracepoint_markers_by_strid>: Return std::vector. * target-debug.h (target_debug_print_VEC_static_tracepoint_marker_p_p): Remove. (target_debug_print_std_vector_static_tracepoint_marker): New. (target_debug_print_struct_static_tracepoint_marker_p): Rename to... (target_debug_print_static_tracepoint_marker_p): ... this. * target-delegates.c: Re-generate. * breakpoint.h (struct tracepoint) <static_trace_marker_id>: Make std::string. * breakpoint.c (init_breakpoint_sal): Adjust to std::string. (decode_static_tracepoint_spec): Adjust to std::vector. (tracepoint_print_one_detail): Adjust to std::string. (strace_marker_decode_location): Adjust to std::string. (update_static_tracepoint): Adjust to std::string, remove call to release_static_tracepoint_marker. * linux-nat.c (linux_child_static_tracepoint_markers_by_strid): Adjust to std::vector. * remote.c (remote_static_tracepoint_marker_at): Return bool. (remote_static_tracepoint_markers_by_strid): Adjust to std::vector. * common/rsp-low.h (hex2str): New overload with explicit count of bytes. * common/rsp-low.c (hex2str): New overload with explicit count of bytes. * unittests/rsp-low-selftests.c (test_hex2str): New function. (_initialize_rsp_low_selftests): Add test_hex2str test. * unittests/tracepoint-selftests.c (test_parse_static_tracepoint_marker_definition): Adjust to std::string.
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.
