X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5a0ade8b7098e7d6a63946835b053b4cca92912e;p=binutils-gdb.git * symbols.c (report_op_error): Remove unnecessary forward declaration. Add "op" parameter. Report operator and operand segments in error message, not operand symbols. (resolve_symbol_value): Always set segment for equated symbols, not just when finalizing.
