* expr.h (enum block_op_methods): Add BLOCK_OP_TAILCALL.
(clear_storage): Add argument.
* expr.c (emit_block_move_via_libcall, clear_storage_via_libcall):
Add tailcall argument, set CALL_EXPR_TAILCALL of the CALL_EXPR to
tailcall.
(emit_block_move): Handle BLOCK_OP_TAILCALL method.
(clear_storage): Add method argument, handle BLOCK_OP_TAILCALL.
(store_expr, store_constructor): Adjust callers.
* builtins.c (expand_builtin_memcpy): Pass BLOCK_OP_TAILCALL
to emit_block_move if CALL_EXPR_TAILCALL (exp).
(expand_builtin_memmove): Add ORIG_EXP argument, copy
CALL_EXPR_TAILCALL from ORIG_EXP to the new CALL_EXPR.
(expand_builtin_bcopy): Replace ARGLIST and TYPE arguments
with EXP. Pass EXP to expand_builtin_memmove.
(expand_builtin_memset): Add ORIG_EXP argument, pass
BLOCK_OP_TAILCALL to clear_storage if CALL_EXPR_TAILCALL (orig_exp).
(expand_builtin_bzero): Replace ARGLIST argument with EXP.
Pass EXP to expand_builtin_memset.
(expand_builtin_strcmp): Copy CALL_EXPR_TAILCALL from EXP to
the new CALL_EXPR.
(expand_builtin_strncmp): Likewise.
(expand_builtin_printf): Replace ARGLIST argument with EXP.
Copy CALL_EXPR_TAILCALL from EXP to the new CALL_EXPR.
(expand_builtin_fprintf): Likewise.
(expand_builtin): Adjust calls to
expand_builtin_{memmove,bcopy,memset,bzero,{,f}printf}.
* gcc.dg/20050503-1.c: New test.
