--- Comment #2 from Peter Bergner <bergner at gcc dot gnu.org> ---
When we compile using -mlong-double-64 -mabi=ibmlongdouble, we get what I'd
expect:
(gdb) ptree type
<real_type 0x7ffff58415a8 __ieee128 KF
size <integer_cst 0x7ffff5741158 type <integer_type 0x7ffff58400a8
bitsizetype> constant 128>
unit-size <integer_cst 0x7ffff5741170 type <integer_type 0x7ffff5840000
sizetype> constant 16>
align:128 warn_if_not_align:0 symtab:0 alias-set -1 canonical-type
0x7ffff58415a8 precision:128>
