re PR tree-optimization/51877 (XEmacs miscompilation due to tail merging)
PR tree-optimization/51877
* tree-ssa-tail-merge.c (gimple_equal_p): Don't return true whenever
call arguments and fndecls compare equal, instead return false if they
don't. Return true only if lhs1 and lhs2 are either both NULL, or
both SSA_NAMEs that are valueized the same, or they satisfy
operand_equal_p.
* gcc.c-torture/execute/pr51877.c: New test.
