That's right, block_lookup_symbol_primary()'s additional requirement over block_lookup_symbol() is: Function is useful if one iterates all global/static blocks of an objfile. Which is satisfied both in lookup_symbol_in_objfile_symtabs() and in lookup_global_symbol_from_objfile() thanks to their's ALL_OBJFILE_COMPUNITS. In fact after reverting that ba715d7fe49c8a59660fbd571b935b29eb7cfbdb above the lines of code were exactly the same. So instead of accelerating both lookup_symbol_in_objfile_symtabs() and lookup_global_symbol_from_objfile() I just accelerated lookup_symbol_in_objfile_symtabs() and I am proposing to reuse lookup_symbol_in_objfile_symtabs() in lookup_global_symbol_from_objfile() instead. In fact such unification would already save some lines of code even before the checked-in acceleration patch above. gdb/ChangeLog 2014-12-05 Jan Kratochvil <jan.kratochvil@redhat.com> * symtab.c (lookup_symbol_in_objfile_symtabs): New declaration. (lookup_global_symbol_from_objfile): Call it.

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.
