says:
GCC versions 4.0 and higher support 128-bit quad precision
floating point values. The XL compilers now provide the
-qfloat=gcclongdouble option to be compatible with GCC's
representation of 128-bit quad precision floating point
values.
Anyone knows how to enable it?
By default, I just get the double-double representation (yielding
106-bit precision).
