--- Comment #16 from sudi at gcc dot gnu.org --- So I think I would go with Jakub's suggestion of defining calls_builtin_setjmp and use that in aarch64_layout_frame for cfun->machine->frame.emit_frame_chain. I am still investigating Wilco's concern over pr60003.c Also I would like to ask if we can pick up the discussions on PR59039 and on the documentation patch. Some definition would be a lot more helpful for someone like me who had no idea about __builtin_setjmp/longjmp to wrap my head around what it actually is. The macro DONT_USE_BUITIN_SETJMP made me very confused for a while until Ramana pointed it out to me that its only used in the context of compiler's exception unwinding machinery and does not apply to a case like this where the user calls the builtin function. With this context in head when I went back and read the document, it made sense. Can we possibly tweak the wording to make it clearer?
