After the previous commit converted symbol-lookup debug to use the new debug scheme, this commit adds SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT. The previous commit didn't add SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT because symbol-lookup debug is controlled by an 'unsigned int' rather than a 'bool' control variable, we use the numeric value to offer different levels of verbosity for symbol-lookup debug. The *_SCOPED_DEBUG_ENTER_EXIT mechanism currently relies on capturing a reference to the bool control variable, and evaluating the variable both on entry, and at exit, this is done in the scoped_debug_start_end class (see gdbsupport/common-debug.h). This commit templates scoped_debug_start_end so that the class can accept either a 'bool &' or an invokable object, e.g. a lambda function, or a function pointer. The existing scoped_debug_start_end and scoped_debug_enter_exit macros in common-debug.h are updated to support scoped_debug_enter_exit being templated, however, nothing outside of common-debug.h needs to change. I've then added SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT in symtab.h, and added a couple of token uses in symtab.c. I didn't want to add too much in this first commit, this is really about updating common-debug.h to support this new functionality. Within symtab.h I created a couple of global functions that can be used to query the status of the symbol_lookup_debug control variable, these functions are then used within the two existing macros: symbol_lookup_debug_printf symbol_lookup_debug_printf_v and also in the new SYMBOL_LOOKUP_SCOPED_DEBUG_ENTER_EXIT macro. |

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.
