double-int.h (lshift): New overload without precision and arith argument.
2013-05-03 Richard Biener <rguenther@suse.de> * double-int.h (lshift): New overload without precision and arith argument. (operator *=, operator +=, operator -=): Move ... * double-int.c (operator *=, operator +=, operator -=): ... here and implement more efficiently. (mul_double_with_sign): Remove. (lshift_double): Adjust to take unsinged shift argument, push dispatching code to callers. (mul_double_wide_with_sign): Add early out for callers that are not interested in high parts or overflow. (lshift): New function. (lshift, rshift, alshift, arshift, llshift, lrshift): Add dispatch code here. (lrotate, rrotate): Use logical shifts. * expr.c (get_inner_reference): Use lshift. * fixed-value.c (do_fixed_divide): Likewise. * tree-dfa.c (get_ref_base_and_extent): Likewise. * tree-ssa-alias.c (indirect_ref_may_alias_decl_p): Likewise. (indirect_refs_may_alias_p): Likewise. (stmt_kills_ref_p_1): Likewise. From-SVN: r198576
