resolve_symbol_value vs. .loc view resolution
In most cases we don't want expression symbols, such as that created for an expression like "symbol + (1f - .)", resolved down to a constant. Instead we'd like to leave the expression as "symbol + constant" once the "1f - ." part has been resolved, and let the backend decide whether "symbol" can be reduced further. However, that doesn't work when trying to resolve .loc view symbols early. We get expression symbols left as an O_symbol expression pointing at an absolute symbol, and marked as sy_flags.sy_resolved. That wouldn't really be a problem, but when one of those expression symbols is used in further .loc view expressions, its value is taken as zero. This patch fixes the symbol value mistake, and stops creation of O_symbol expression symbols pointing to absolute symbols. Either of these fixes would cure the .loc view usage. PR 24444 * symbols.c (resolve_symbol_value): When handling symbols marked as sy_flags.resolved, return correct value for the case of expression symbols left as an O_symbol expression. Merge O_symbol code handling undefined and common symbols with code handling special cases of expression symbols. Use seg_left to test for undefined and common symbols. Don't leave an O_symbol expression when X_add_symbol resolves to the absolute_section. Init final_val later. * testsuite/gas/mmix/basep-7.d: Adjust expected output.

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.
