xtensa.c (xtensa_build_va_list): Use lang_hooks.types.make_type instead of make_node; set up __va_list_tag type decl.
* config/xtensa/xtensa.c (xtensa_build_va_list): Use
lang_hooks.types.make_type instead of make_node; set up
__va_list_tag type decl.
(xtensa_builtin_saveregs): Remove broken use of
RTX_UNCHANGING_P and unnecessary use of MEM_IN_STRUCT_P
for saved registers; add varargs alias set.
