Right now some psymtab code checks whether a psymtab's textlow or texthigh fields are valid by comparing against 0. I imagine this is mildly wrong in the current environment, but once psymtabs are relocated dynamically, it will no longer be correct, because it will be much more normal to see a psymtab with a textlow of zero -- this will just mean it appears at the start of the text section. This patch introduces validity bits to handle this situation more nicely, and changes users of the code to follow. gdb/ChangeLog 2018-07-26 Tom Tromey <tromey@redhat.com> * dbxread.c (end_psymtab): Use text_high_valid and text_low_valid. * mdebugread.c (parse_partial_symbols): Use text_low_valid. (psymtab_to_symtab_1): Use text_high_valid and text_low_valid. * psympriv.h (struct partial_symtab) <m_text_low, m_text_high>: Update comment. <text_low_valid, text_high_valid>: New fields. <set_text_low, set_text_high>: Update. * xcoffread.c (scan_xcoff_symtab): Use text_low_valid. |

README
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.
