builtins.c (expand_builtin_alloca): allocate_dynamic_stack_space returns Pmode pseudo, but we need ptr_mode.
* builtins.c (expand_builtin_alloca): allocate_dynamic_stack_space
returns Pmode pseudo, but we need ptr_mode.
* explow.c (allocate_dynamic_stack_space): Use plus_constant.
Remove bogus conversions; use HOST_WIDE_INT for size.
Don't use TARGET if wrong mode.
