Binutils with MCST patches
2716529498
There's two ways to set breakpoints in GDBServer. - GDBServer setting its own breakpoints, through API set_breakpoint_at. - GDBServer setting breakpoints according to the information in Z packets, through API set_gdb_breakpoint. Before this patch the breakpoint kinds were a concept unique to GDB and Z packets, as GDBServer never had to set different kinds of breakpoint on its own. This patch teaches GDBServer to handle breakpoint kinds for its own breakpoints. It generalizes the breakpoint kind as per Z packets to represent different kinds of breakpoints directly set by GDBServer also. GDBServer now querys breakpoint_kind_from_pc to know what breakpoint kind to set on its own. As the kind is now a differentiating factor equivalent to size for the breakpoint struct and that it's size can be queried using sw_breakpoint_from_kind, the size field has been replaced with the kind field. All references to size are now replaced by kind or a call to bp_size that wraps sw_breakpoing_from_kind and returns the size of the breakpoint in memory. To fetch the software breakpoint data bp_opcode is called and wraps the sw_breakpoint_from_kind call. No regressions on Ubuntu 14.04 on ARMv7 and x86. With gdbserver-{native,extended} / { -marm -mthumb } gdb/gdbserver/ChangeLog: * linux-low.c (initialize_low): Ajdust for breakpoint global variables removal. * mem-break.c : Remove breakpoint_data/breakpoint_len global variables. (struct raw_breakpoint) <size>: Remove. (struct raw_breakpoint) <kind>: Add. (bp_size): New function. (bp_opcode): Likewise. (find_raw_breakpoint_at): Adjust for kind. (insert_memory_breakpoint): Adjust for kind call bp_size,bp_opcode. (remove_memory_breakpoint): Adjust for kind call bp_size. (set_raw_breakpoint_at): Adjust for kind. (set_breakpoint): Likewise. (set_breakpoint_at): Call breakpoint_kind_from_pc. (delete_raw_breakpoint): Adjust for kind. (delete_breakpoint): Likewise. (find_gdb_breakpoint): Likewise. (set_gdb_breakpoint_1): Likewise. (set_gdb_breakpoint): Likewise. (delete_gdb_breakpoint_1): Likewise. (delete_gdb_breakpoint): Likewise. (uninsert_raw_breakpoint): Likewise. (reinsert_raw_breakpoint): Likewise. (set_breakpoint_data): Remove. (validate_inserted_breakpoint): Adjust for kind call bp_size,bp_opcode. (check_mem_read): Adjust for kind call bp_size. (check_mem_write): Adjust for kind call bp_size,bp_opcode. (clone_one_breakpoint): Adjust for kind. * mem-break.h (set_gdb_breakpoint): Likewise. (delete_gdb_breakpoint): Likewise. * server.c (process_serial_event): Likewise. |

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.
