Re: [Valgrind-users] valgrind breaks any long double operation on x86-64

Not that they support as full speed hardware operations, AFAIK. SPARC has defined
registers and instructions for 128-bit floating point, but implements them as
sequences of operations on 64-bit floats, so they aren't terribly fast.

IBM System/390 onwards supports 128-bit float in hardware, according to Wikipedia.
