arm_builtin_decl (unsigned code, bool initialize_p ATTRIBUTE_UNUSED)
{
unsigned subcode = code >> ARM_BUILTIN_SHIFT;
switch (code & ARM_BUILTIN_CLASS)
{
case ARM_BUILTIN_GENERAL:
return arm_general_builtin_decl (subcode);
case ARM_BUILTIN_MVE:
return error_mark_node;
^^^
I guess that's the problem. MVE builtins are not handled at all?
