Performance optimize large bp_location count. * breakpoint.c (ALL_BP_LOCATIONS_SAFE): Remove. (ALL_BP_LOCATIONS): New parameter BP_TMP. Use now bp_location and bp_location_count. (bp_location_chain): Remove variable. (bp_location, bp_location_count) (bp_location_placed_address_before_address_max) (bp_location_shadow_len_after_address_max): New variables. (moribund_locations, update_watchpoint): Update the bp_location variable name. (breakpoint_restore_shadows): Extend the comment. Move the variable b to local blocks. Move the variables bp_addr, bp_size and bptoffset to a local block. New variables bc_l, bc_r and bc. New binary search for the left range boundary. New break on reaching the right range boundary. Move shadow existence conditionals to ... (bp_location_has_shadow): ... a new function. (insert_breakpoint_locations): Replace the temp variable by bp_tmp. Use now ALL_BP_LOCATIONS instead of ALL_BP_LOCATIONS_SAFE. (remove_breakpoints, remove_hw_watchpoints, reattach_breakpoints) (detach_breakpoints): New variable bp_tmp. Update the ALL_BP_LOCATIONS calling convention. (update_breakpoints_after_exec): New variable bplocp_tmp. Update the ALL_BP_LOCATIONS calling convention. (breakpoint_here_p, software_breakpoint_inserted_here_p) (breakpoint_thread_match): New variable bptp_tmp. Drop the const attribute of bpt. Update the ALL_BP_LOCATIONS calling convention. (regular_breakpoint_inserted_here_p): Likewise. Update the bp_location variable name. (mark_breakpoints_out, breakpoint_init_inferior): New variable bptp_tmp. Update the ALL_BP_LOCATIONS calling convention. (bpstat_stop_status): New variables blp_tmp and update_locations. Drop the const attribute of bl. Update the ALL_BP_LOCATIONS calling convention. Protect HIT_COUNT increment by an ENABLE_STATE check. Delay the update_global_location_list call using update_locations. (set_default_breakpoint): Drop the check_duplicates name from comment. (disable_breakpoints_in_shlibs, disable_breakpoints_in_unloaded_shlib): New variable locp_tmp. Update the ALL_BP_LOCATIONS calling convention. (bp_location_compare, bp_location_compare_for_qsort) (bp_location_target_extensions_update): New functions. (check_duplicates, check_duplicates_for): Remove, moving their code ... (update_global_location_list): ... into this existing function. Remove variables next, loc2, old_locations, ret and ix. New variables locp, loc_first, old_location, old_locp and old_location_count. Stop using global_next, create now the array bp_location, sort it by bp_location_compare_for_qsort and call bp_location_target_extensions_update. Change quadratic iteration by loc2 into an in-sync scanning by locp and loc2p. Rename former loc usage as old_loc. (do_vec_free): Remove. (breakpoint_program_space_exit): Update the ALL_BP_LOCATIONS calling convention. (remove_breakpoints_pid): New variable b_tmp. Update the ALL_BP_LOCATIONS calling convention. * breakpoint.h (struct bp_location <global_next>): 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.
