This patch converts the function pointers in dwarf_expr_context_funcs into methods on dwarf_expr_context, and then updates the various implementations and callers to follow. NB this patch uses "override" (which caught a couple of renaming bugs during development) -- but this is C++11, so this patch at least has to wait for Pedro's patch that adds the OVERRIDE macro. After this patch it would be possible to do one more, that makes various members of dwarf_expr_context "protected"; but I haven't done this. 2016-10-21 Tom Tromey <tom@tromey.com> * dwarf2loc.c (struct dwarf_expr_context_funcs): Don't declare. (dwarf_expr_read_addr_from_reg, dwarf_expr_get_reg_value) (dwarf_expr_read_mem, dwarf_expr_frame_base): Rename; turn into methods. (get_frame_pc_for_per_cu_dwarf_call): New function. (dwarf_expr_frame_cfa, dwarf_expr_frame_pc) (dwarf_expr_tls_address): Rename; turn into methods. (per_cu_dwarf_call): Remove arguments. Use get_frame_pc_for_per_cu_dwarf_call. (dwarf_evaluate_loc_desc): New class. (dwarf_expr_dwarf_call, dwarf_expr_context) (dwarf_expr_push_dwarf_reg_entry_value) (dwarf_expr_get_addr_index, dwarf_expr_get_obj_addr): Rename; turn into methods. (dwarf_expr_ctx_funcs): Remove. (dwarf2_evaluate_loc_desc_full): Update. (dwarf2_locexpr_baton_eval): Update. (symbol_needs_eval_context): New class. (symbol_needs_read_addr_from_reg, symbol_needs_get_reg_value) (symbol_needs_read_mem, symbol_needs_frame_base) (symbol_needs_frame_cfa, symbol_needs_tls_address) (symbol_needs_dwarf_call, needs_dwarf_reg_entry_value): Rename; turn into methods. (needs_get_addr_index, needs_get_obj_addr): Remove; turn into methods. (symbol_needs_ctx_funcs): Remove. (dwarf2_loc_desc_get_symbol_read_needs): Update. * dwarf2expr.h (struct dwarf_expr_context_funcs): Remove; turn contents into methods. (struct dwarf_expr_context) <baton, funcs>: Remove. <read_addr_from_reg, get_reg_value, read_mem, get_frame_base, get_frame_cfa, get_frame_pc, get_tls_address, dwarf_call, impl_get_base_type, push_dwarf_block_entry_value, get_addr_index, get_object_address>: Declare new methods. (ctx_no_get_frame_base, ctx_no_get_frame_cfa) (ctx_no_get_frame_pc, ctx_no_get_tls_address, ctx_no_dwarf_call) (ctx_no_get_base_type, ctx_no_push_dwarf_reg_entry_value) (ctx_no_get_addr_index): Don't declare. * dwarf2expr.c (get_base_type): Use impl_get_base_type. (execute_stack_op): Update. (ctx_no_get_frame_base, ctx_no_get_frame_cfa) (ctx_no_get_frame_pc, ctx_no_get_tls_address, ctx_no_dwarf_call) (ctx_no_get_base_type, ctx_no_push_dwarf_reg_entry_value) (ctx_no_get_addr_index): Remove; now methods on dwarf_expr_context. * dwarf2-frame.c (read_addr_from_reg): Take a frame_info, not a baton. (class dwarf_expr_executor): New class. (get_reg_value, read_mem): Rename, turn into methods. (execute_stack_op): Use dwarf_expr_executor. |

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.
