>   For S390, type code 'g' is used for 128-bit long double literals

There is also a historical mode of using IEEE-64 as "long double" on s390, where we also used 'e' to mangle it.   However, this hasn't been used anywhere for the last 15 years or so.  It is still supported via -mlong-double-64 in GCC; I see clang also supports this argument, but I'm not actually sure it works on s390 (I've certainly never tested it).
