re PR tree-optimization/46076 (constant propagation and compile-time math no longer happening versus 4.4 and 4.5)
2011-04-12 Richard Guenther <rguenther@suse.de>
PR tree-optimization/46076
* gimple.h (struct gimple_statement_call): Add fntype field.
(gimple_call_fntype): Adjust.
(gimple_call_set_fntype): New function.
* gimple.c (gimple_build_call_1): Set the call function type.
* gimplify.c (gimplify_call_expr): Preserve the function
type the frontend used for the call.
(gimplify_modify_expr): Likewise.
* lto-streamer-in.c (input_gimple_stmt): Input the call stmts
function type.
* lto-streamer-out.c (output_gimple_stmt): Output the call stmts
function type.
* tree-ssa.c (useless_type_conversion_p): Function pointer
conversions are useless.
* gcc.dg/tree-ssa/pr46076.c: Un-XFAIL.
