--- Comment #3 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Alan Modra <amo...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=1903f1385bff910861942743860d8577423bcb6c commit 1903f1385bff910861942743860d8577423bcb6c Author: Alan Modra <amo...@gmail.com> Date: Wed Apr 24 11:26:51 2019 +0930 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. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
