Thank you for your feedback. `isTypeLegal` has the following description:
`/// Return true if the target has native support for the specified value type.`
I thought that quad-precision would be supported if libcall could be used, even without native support, so I also checked the legalize action. However, `isTypeLegal` returns true even for targets where the legalize action is `LibCall` (aarch64, x86_64), so it might not be necessary. I may be misunderstanding the meaning of "native support."
