| /* We order the 3 128-bit floating point types so that IFmode (IBM 128-bit |
| floating point) is the 128-bit floating point type with the highest |
| precision (128 bits). This so that machine independent parts of the |
| compiler do not try to widen IFmode to TFmode on ISA 3.0 (power9) that has |
| hardware support for IEEE 128-bit. We set TFmode (long double mode) in |
| between, and KFmode (explicit __float128) below it. |
| |
| We won't encounter conversion from IEEE 128-bit to IBM 128-bit because we |
| don't have insns to support the IBM 128-bit aritmetic operations. */ |
