This allows better interoperability mixing small/medium/large code model code since large code model data can be put into separate large sections. And respect large data threshold under large code model. gcc also does this: https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html. See https://groups.google.com/g/x86-64-abi/c/jnQdJeabxiU.
