builtins.c (expand_builtin_setjmp): Only call convert_memory_address if needed.
* builtins.c (expand_builtin_setjmp): Only call convert_memory_address
if needed.
(expand_builtin_longjmp, expand_builtin_alloca): Likewise.
* except.c (expand_builtin_frob_return_addr): Likewise.
(expand_builtin_eh_return): Likewise.
* stmt.c (expand_computed_goto): Likewise.
* explow.c (memory_address): Likewise.
(allocate_dynamic_stack_space): Clean up predicate testing.
(probe_stack_range): Convert SIZE to Pmode.
* calls.c (rtx_for_function_call): Only call convert_memory_address
if needed.
Pass function call operand as ptr_mode, not Pmode.
* expr.c (expand_assignment): Clean up calls to convert_memory
address by only doing so when needed and making offsets Pmode.
(store_constructor, expand_expr, expand_expr_unaligned): Likewise.
* function.c (assign_parms): Ensure address in MEM for RESULT_DECL
is in Pmode, not ptr_mode.
