2005-12-22 Jan Beulich <jbeulich@novell.com> * symbols.h (snapshot_symbol): First parameter is now pointer to pointer to symbolS. * symbols.c (snapshot_symbol): Likewise. Store resulting symbol there. Use symbol_equated_p. * expr.c (resolve_expression): Change first argument to snapshot_symbol. Track possibly changed add_symbol consistently across function. Resolve more special cases with known result. Also update final_val when replacing add_symbol. gas/testsuite/ 2005-12-22 Jan Beulich <jbeulich@novell.com> * gas/all/cond.s: Also check .if works on equates to undefined when the expression value can be known without knowing the value of the symbol. * gas/all/cond.l: Adjust. * gas/i386/equ.s: Also check .if works on (equates to) registers when the expression value can be known without knowing the value of the register. * gas/i386/equ.e: Adjust.
